ABS/PA多少钱一公斤？选型省钱，丙烯腈丁二烯苯乙烯尼龙合金的价格藏在PA比例里

这个问题一搜，从十八块到四十五块，报价差得比PA比例还多。有人说我买的十八的国产通用用得挺好，有人说我买的四十五的进口高耐热才叫高端。到底差在哪？

说实话，问ABS/PA多少钱一公斤的人，大概率还没搞懂ABS/PA这东西不是一个料——通用级、高耐热级、高抗冲级、低吸湿级、阻燃级、玻纤增强级，每个分支价格都不一样。你拿通用级的价和高耐热比，那不叫比价，叫被忽悠。

先搞懂它是什么料，再谈钱

ABS/PA就是丙烯腈丁二烯苯乙烯/尼龙合金，市面上流通的大多是PA6/ABS合金。它把ABS的易加工、高光泽、低温韧性，和PA的高强度、耐热、耐化学、耐磨揉进一个牌号里，常用于汽车门板拉手盒、时钟罩、出风口、仪表骨架，家电的空调面板、冰箱门板、吸尘器壳体，还有电动工具壳体、园艺工具。

一句话记忆：ABS负责好看好做，PA负责扛造耐热。PA占比越高，越往扛造那一端走，价格也越往上走。你连它是哪一档都分不清，就盯着公斤价问贵不贵，等于连菜的荤素都没看，先问这桌多少钱。

牌号地图：名字里藏着性能密码

价格篇先摆牌号。市面上主流ABS/PA，外企端绕不开大赛璐（Daicel）的Novalloy A系列，国产端有锦湖日丽、金发、普利特等改性大厂，还有大量中小改性厂做的PA6/ABS通用改性料。以下为近期市场参考，牌号物性来自公开物性表，价格为市场大致区间，实时价格以当日询价为准。

进口ABS/PA（外企大厂）

国产ABS/PA（中企大厂及改性厂）

一句话总结：国产通用19-28块，国产高耐热/玻纤增强20-34块，进口通用25-35块，进口高耐热/高抗冲/阻燃30-45块。你要的是哪一档的PA比例和性能，决定了你该在哪一档选。

十八的和四十五的，钱花在了哪里

ABS/PA的出厂价，大头是两袋基料：ABS粒子加PA粒子。尼龙的单价比ABS高，PA比例越高，成本越高，这是第一层。第二层是增强和功能化：加玻纤要配偶联剂和相容剂，做阻燃要加阻燃剂，每一层都是钱。第三层是研发和品控：进口大厂贵，贵在批次稳定性和技术服务，不是贵在塑料本身。

给你一个粗略的价格构成直觉，方便你对着报价单反推水分：

价差藏在四个地方，每一个你都能自己验

第一，PA比例不同。低PA便宜，高PA贵。怎么验？看COA或送检密度——纯ABS密度大约1.04-1.06，PA6大约1.13-1.15，PA混得越多，整包料密度越高。密度一测，比例高低瞒不住。

第二，耐热等级不同。通用级便宜，高耐热级贵。怎么验？别听牌号，直接测热变形温度（HDT），测出来才算数。同一个牌号不同批次都可能波动，更别说销售嘴里的差不多。

第三，增强方式不同。无筋通用便宜，玻纤增强贵，通常比无筋贵20-40%。怎么验？灼烧后看灰分，玻纤含量越高灰分越高，一把酒精喷灯就能看出七八分。

第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但牌号少。同样是高耐热级，进口比国产贵30-50%，贵的是品控和研发。买谁的，看你赌不赌得起批次翻车。

采购这行，水比你想的深

我见过太多采购，比价比到最后选了最便宜的十八的，然后做出来的制品耐热差、强度不够、客户退货，一次损失够买半年的好料。三个坑必须绕开：

第一，看性能不看牌号。拿到料先测热变形温度和缺口冲击，和COA对得上再用。别听销售说差不多，差不多就是差很多。

第二，警惕以次充好。有些贸易商拿ABS当ABS/PA卖，拿低PA当高PA卖。要COA、要PA比例检测、要原厂包装，三证合一才敢用。裸包散料一律按来路不明处理。

第三，别只比单价，算综合成本。A料单价18块，做出来制品次品率5%；B料单价28块，次品率1%。算到每件制品上，B料反而更便宜。单价便宜是假便宜，摊到制品上算得平才是真便宜。

别比单价，算总账

来算一笔实在的账。一件制品用料约0.1公斤，A料国产通用20元/公斤，B料进口高耐热35元/公斤，做同一款件：

光看料损这一项，B料就扳回来了650块，还没算报废件的注塑工时、模具损耗、返工成本和延期交付。账算到全生命周期，你会发现便宜的料往往最贵。这就是为什么我一直说：单价是门槛，性能是底线，把账算到每件制品上，你才知道谁真便宜谁真贵。

原料一涨，报价就跟着心跳

做采购的，行情得看得懂。ABS/PA的报价跟着两类原料走：ABS看苯乙烯、丙烯腈、丁二烯三料，PA看己内酰胺（PA6）或己二酸、己二胺（PA66）。

传导路径不复杂：原油一动，石脑油跟着动，苯乙烯、丙烯腈跟着动，ABS报价就动；己内酰胺供需一紧，PA6就涨，PA/ABS合金跟着涨。所以哪天你看到今日ABS涨了五百、PA6涨了八百，心里就该有数：ABS/PA合金的报价单，也该松动了。原料涨不是厂家黑，是成本真上去了；反过来原料跌的时候报价还死扛的，那才要留个心眼。

需求不会写牌号，选型要对号入座

别让报价单替你做决定，先搞清楚你的制品要什么，再对号入座：

标准料是大锅饭，改性料是定制菜

如果你发现标准牌号怎么选都差点意思——比如要高耐热又要高抗冲、要低吸湿又要高流动、要低成本又要阻燃——那不是ABS/PA的问题，是你需要的不是标准ABS/PA，是改性ABS/PA。

这时候可以看看宁波科隆新材目前在做的高性能改性ABS/PA方案，玻纤增强、阻燃、耐候、导电这些方向都有对应牌号在做。有特殊需求的可以私信要一份改性ABS/PA的报价参考，比自己买基料再加助剂调试，省的不只是钱，还有试错的时间。

说白了，标准料是大锅饭，改性料是定制菜。你的制品要求越高，越需要定制。

常用牌号，私信给你当日报价

上面的价格都是参考价，ABS/PA行情一天一个样，苯乙烯、丙烯腈、丁二烯、己内酰胺、玻纤、阻燃剂、汇率都在动。

如果你需要进口、国产这些品牌的具体牌号当日报价，私信我，发你一份实时价格表。不绕弯子，报实数。

写在最后

买ABS/PA这事儿，十八的和四十五的，差的不是二十七。

单价是门槛，PA比例和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高耐热汽车配件的方案。把账算到每件制品上，再加上次品退货损失，你才知道谁真便宜谁真贵。

这几天后台问得最多的，翻来覆去就三件事：一是拿着ABS通用级的报价来比ABS/PA高耐热，觉得人家卖十八自己卖二十几，是不是被宰了；二是到货不验PA比例，密度一测对不上，才知道被以次充好；三是ABS和ABS/PA分不清，装机跑了几个月才发现耐热和强度都差一口气。踩过坑的都懂——耐热差了制品高温变形，强度不够了装机就裂，比价省下的那点单价，一趟趟返工全填了回去。

说到底，ABS/PA和ABS到底差在哪、PA比例怎么选、具体牌号当日报价是多少，这些事聊起来比报价单上一串数字实在。有需要的，私信聊，不绕弯子，报实数。

A quick search shows quotes ranging from CNY 18 to CNY 45 per kilo — a spread wider than the PA ratio itself. Some buyers say the CNY 18 domestic general-purpose grade works fine; others insist only the CNY 45 imported high-heat grade counts as premium. Where does the difference really lie?

Honestly, anyone asking "how much is ABS/PA per kilo" probably has not yet understood that ABS/PA is not a single material — general-purpose, high-heat, high-impact, low-moisture, flame-retardant and glass-fiber-reinforced grades each carry a different price. Comparing a general-purpose quote with a high-heat one is not price comparison; it is how you get fooled.

First understand what the material is, then talk money

ABS/PA is an acrylonitrile-butadiene-styrene/nylon alloy, and most material circulating on the market is PA6/ABS. It blends ABS's ease of processing, high gloss and low-temperature toughness with PA's high strength, heat resistance, chemical resistance and abrasion resistance in one grade. Typical applications include automotive door panels, handle boxes, clock covers, air vents and instrument skeletons; appliance control panels, refrigerator door panels and vacuum cleaner housings; plus power tool housings and garden tools.

One-line memory: ABS makes it look good and process well; PA makes it tough and heat-resistant. The higher the PA share, the more it leans toward "tough" — and the higher the price climbs. If you cannot even tell which tier a material belongs to and just ask whether the per-kilo price is expensive, it is like asking the price of the whole table before checking whether the dishes are meat or vegetables.

Grade map: the name hides the performance code

Let's lay out the grades first. On the import side, Daicel's Novalloy A series dominates the ABS/PA field; on the domestic side there are compounders such as Kumho Sunny, Kingfa and Polyrocks, plus a large number of small and medium compounders making general PA6/ABS blends. Below are recent market references — grade properties come from public datasheets, prices are approximate market ranges, and live prices are subject to same-day inquiry.

Imported ABS/PA (overseas majors)

Domestic ABS/PA (Chinese majors and compounders)

In short: domestic general-purpose CNY 19-28, domestic high-heat/GF-reinforced CNY 20-34, imported general-purpose CNY 25-35, imported high-heat/high-impact/flame-retardant CNY 30-45. The PA ratio and performance tier you need decide where you pick.

Where the money goes between CNY 18 and CNY 45

The ex-works cost of ABS/PA is mostly two base ingredients: ABS pellets plus PA pellets. Nylon costs more per kilo than ABS, so the higher the PA ratio, the higher the cost — that is layer one. Layer two is reinforcement and functionalization: glass fiber needs coupling agents and compatibilizers; flame retardancy needs FR additives; every layer costs money. Layer three is R&D and quality control: imported majors charge more for batch-to-batch stability and technical service, not for the plastic itself.

Here is a rough cost-structure intuition so you can reverse-engineer the water in any quote:

The price gap hides in four places, and you can verify each yourself

First, PA ratio. Low PA is cheap; high PA is expensive. How to verify? Check the COA or send out for density — pure ABS density is about 1.04-1.06, PA6 about 1.13-1.15. The more PA blended in, the higher the density of the whole bag. One density test and the ratio cannot hide.

Second, heat resistance grade. General-purpose is cheap; high-heat is expensive. How to verify? Don't trust the grade name — measure heat deflection temperature (HDT) directly. Only measured numbers count. Even the same grade can fluctuate between batches, let alone a salesperson's "close enough."

Third, reinforcement. Unfilled general-purpose is cheap; glass-fiber reinforced costs more, usually 20-40% above unfilled. How to verify? Burn the material and check ash content — more glass fiber, more ash. An alcohol blowtorch reveals 70-80% of the truth.

Fourth, brand and origin. Imports carry a premium but offer batch stability; domestic grades offer value but fewer options. For the same high-heat grade, imported costs 30-50% more than domestic — you pay for quality control and R&D. Whose to buy depends on whether you can afford a bad batch.

Procurement is deeper water than you think

I have seen too many buyers end up choosing the cheapest CNY 18 material after endless price comparison, only to have parts fail on heat resistance and strength, trigger customer returns — one loss enough to buy half a year of good material. Three traps must be avoided:

First, test performance, not grade names. Measure HDT and notched impact against the COA before use. Don't listen to "close enough" — close enough is far apart.

Second, watch out for substitution fraud. Some traders sell ABS as ABS/PA, or low-PA as high-PA. Demand the COA, a PA-ratio test and original packaging. Only accept material with all three. Bare bulk bags should be treated as unknown origin.

Third, don't compare unit price alone — calculate total cost. Material A at CNY 18/kg yields a 5% defect rate; material B at CNY 28/kg yields 1%. Per finished part, B is actually cheaper. A cheap unit price is fake cheap; a price that balances out per finished part is real cheap.

Don't compare unit price — calculate the total account

Let's do a real calculation. A part uses about 0.1 kg of material. Material A is domestic general-purpose at CNY 20/kg; material B is imported high-heat at CNY 35/kg, making the same part:

On material loss alone, B already wins back CNY 650 — before counting injection molding hours, mold wear, rework and late-delivery penalties for scrapped parts. Count the full life cycle and you find the cheap material is usually the most expensive. That is why I always say: unit price is the threshold, performance is the baseline. Do the math per finished part and you will know who is truly cheap and who is truly expensive.

When feedstock prices move, quotes follow the heartbeat

If you buy materials, you need to read the market. ABS/PA quotes follow two feedstock chains: ABS tracks styrene, acrylonitrile and butadiene; PA tracks caprolactam (PA6) or adipic acid and hexamethylenediamine (PA66).

The transmission path is not complicated: crude moves, naphtha follows, styrene and acrylonitrile follow, and ABS quotes move; when caprolactam supply tightens, PA6 rises and PA/ABS alloys follow. So the day you see ABS up CNY 500 and PA6 up CNY 800, you should already know: the ABS/PA alloy quote is about to loosen up too. A feedstock rise is not the supplier being greedy — cost really went up. And when feedstock falls while quotes hold firm, that is when you should be suspicious.

Demand never writes a grade name — match selection to application

Don't let the quote sheet decide for you. First figure out what your part needs, then match:

Standard grades are a big pot of rice; modified compounds are cooked to order

If standard grades always fall short — you need high heat AND high impact, low moisture AND high flow, or low cost AND flame retardancy — the problem is not ABS/PA itself; you don't need standard ABS/PA, you need modified ABS/PA.

Ningbo Kolong New Materials is developing high-performance modified ABS/PA solutions, with grades covering glass-fiber reinforcement, flame retardancy, weather resistance and conductivity. For special needs, message us for a modified ABS/PA quote reference — it saves not only money but also trial-and-error time compared with buying base resin and tuning additives yourself.

In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order. The higher your requirements, the more you need customization.

Final words

Buying ABS/PA — the difference between CNY 18 and CNY 45 is not CNY 27.

Unit price is the threshold; PA ratio and performance are the baseline. Don't let the quote sheet fool you — you are not buying one kilogram of plastic, you are buying a solution for making heat-resistant automotive parts. Do the math per finished part, add in the loss from rejected goods, and you will know who is truly cheap and who is truly expensive.

The most frequent questions in our inbox boil down to three things: buyers comparing a general-purpose ABS quote with a high-heat ABS/PA quote and suspecting they are being overcharged; receiving material without verifying the PA ratio and finding the density does not match; and confusing ABS with ABS/PA, only discovering months into production that heat resistance and strength fall short. Those who have been burned understand — poor heat resistance means parts deform under high temperature, insufficient strength means cracks on assembly, and every bit of unit price saved gets swallowed by round after round of rework.

At the end of the day, what really separates ABS/PA from ABS, how to choose the PA ratio, and what same-day quotes for specific grades look like — these are more practical than a string of numbers on a quote sheet. If you need them, message us. No beating around the bush — real numbers.
