CPVC多少钱一公斤？
这个问题一搜，从九块五一公斤到三十三块一公斤，报价差得比氯含量还多。有人说我买的九块五的国产J-700粉末用得挺好，有人说我买的三十三的路博润88077才叫高流动。到底差在哪？
说实话，问CPVC多少钱一公斤的人，大概率还没搞懂CPVC这东西不是一个料——树脂粉末、注塑级、挤出级、管材级、高流动级，每个分支价格都不一样。你拿粉末的价和注塑级比，那不叫比价，叫被忽悠。
一、主流牌号报价（外企+中企）
先把市面上走量的牌号和参考价摆出来。以下为近期市场参考价，实时价格以当日询价为准。
路博润（Lubrizol，美国）
TempRite 88077，阻燃耐候高流动耐腐蚀，参考价约27.5-33元/公斤。管道应用、电子电器。
TempRite 88023，抗冲击耐高温，参考价约28元/公斤。通用注塑、管材。
TempRite 88096，耐高温高刚性阻燃耐强腐蚀，参考价约20-21元/公斤。管材专用、工业管道。
积水化学（Sekisui，日本）
积水CPVC注塑级，参考价约25-35元/公斤。高耐热、耐腐蚀，化工管道、电子部件。
国产CPVC（山东高信/新疆天业等中企大厂）
J-700树脂粉末，参考价约9.5-10.5元/公斤。管材级原料，需自行加工。
国产注塑级，参考价约15-25元/公斤。性价比高，通用注塑、管材。
国产挤出级，参考价约12-20元/公斤。板材、管材、型材。
一句话总结：树脂粉末9-11块，挤出级12-20块，注塑级15-28块，高流动/耐腐蚀25-35块。你要的是啥形态和氯含量，决定了你该在哪一档选。
二、同是CPVC，价差凭什么这么大
CPVC的价格差，主要藏在四个地方。
第一，氯含量不同。普通CPVC氯含量63%左右便宜，高氯含量67%以上耐热更好价格贵。氯含量每提升1%，耐热温度升5-8℃。
第二，形态不同。树脂粉末便宜，注塑/挤出颗粒贵。粉末需要自行加工，颗粒可以直接用。
第三，加工性能不同。通用级流动一般价格便宜，高流动级适合薄壁和复杂结构价格贵。高流动CPVC需要特殊配方。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但质量参差。同样是注塑级，路博润比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让氯含量骗了你
我见过太多采购，比价比到最后选了最便宜的九块五的粉末，然后自己加工出来的管材耐热不够、开裂、客户退货，一次损失够买半年的好料。
CPVC采购这行，水比你想的深。三个坑必须绕开：
第一，看维卡软化温度和氯含量不看牌号。同一个牌号不同批次性能可能波动，拿到料先测维卡温度和氯含量，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PVC当CPVC卖，拿低氯当高氯卖。要COA、要氯含量检测、要原厂包装，三证合一才敢用。
第三，别只比单价，算综合成本。A料单价9.5块，自己加工成本加5块，次品率5%；B料单价25块，直接用，次品率1%。算到每件制品上，B料反而更便宜。
四、标准牌号满足不了？看看改性方案
如果你发现标准牌号怎么选都差点意思——比如要阻燃又要高抗冲、要耐热又要高流动、要低成本又要耐腐蚀——那不是CPVC的问题，是你需要的不是标准CPVC，是改性CPVC。
这时候可以看看宁波科隆新材目前在做的高性能改性CPVC方案，抗冲、阻燃、高流动、耐腐蚀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CPVC的报价参考，比自己买粉末再加助剂调试，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。
五、常用牌号，私信给你当日报价
上面的价格都是参考价，CPVC行情一天一个样，氯气、PVC树脂、汇率都在动。
如果你需要路博润、积水化学、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CPVC这事儿，九块五的和三十三的，差的不是二十三点五。
单价是门槛，选对氯含量和形态才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出耐热管材的方案。把账算到每件制品上，再加上加工成本和次品损失，你才知道谁真便宜谁真贵。

How much is CPVC per kilogram? Today's quotes — chlorinated PVC prices follow chlorine content
How much is CPVC per kilogram?
A quick search shows quotes ranging from CNY 9.5/kg to CNY 33/kg — a spread wider than the chlorine content itself. Some buyers say the CNY 9.5 domestic J-700 powder works fine; others insist only the CNY 33 Lubrizol 88077 counts as high flow. Where does the difference really lie?
Honestly, anyone asking "how much is CPVC per kilo" probably has not yet understood that CPVC is not a single material — resin powder, injection grade, extrusion grade, pipe grade and high-flow grade each carry a different price. Comparing a powder quote with an injection grade is not price comparison; it is how you get fooled.
1. Mainstream grade quotes (imported + domestic)
Here are the high-volume grades and reference prices on the market. Figures below are recent market references; live prices are subject to same-day inquiry.
Lubrizol (USA)
TempRite 88077, flame-retardant, weather-resistant, high-flow, corrosion-resistant, approx. CNY 27.5-33/kg. Pipe applications, electronics.
TempRite 88023, impact-resistant, high-temperature resistant, approx. CNY 28/kg. General injection molding, pipe.
TempRite 88096, high-temperature, high-rigidity, flame-retardant, strong corrosion-resistant, approx. CNY 20-21/kg. Pipe dedicated, industrial pipe.
Sekisui Chemical (Japan)
Sekisui CPVC injection grade, approx. CNY 25-35/kg. High heat and corrosion resistance; chemical piping, electronic components.
Domestic CPVC (Shandong Gaoxin, Xinjiang Tianye and other Chinese majors)
J-700 resin powder, approx. CNY 9.5-10.5/kg. Pipe-grade feedstock; requires in-house processing.
Domestic injection grade, approx. CNY 15-25/kg. Cost-effective; general injection molding, pipe.
Domestic extrusion grade, approx. CNY 12-20/kg. Sheet, pipe, profiles.
In short: resin powder CNY 9-11, extrusion grade CNY 12-20, injection grade CNY 15-28, high-flow/corrosion-resistant CNY 25-35. The form and chlorine content you need decide which tier you belong in.
2. Why do CPVC prices differ so much
The CPVC price gap mainly hides in four factors.
First, chlorine content. Ordinary CPVC with about 63% chlorine is cheap; high-chlorine grades above 67% offer better heat resistance and cost more. Every 1% increase in chlorine raises the heat resistance by 5-8°C.
Second, form. Resin powder is cheap; injection/extrusion pellets cost more. Powder requires in-house processing; pellets are ready to use.
Third, processability. General grades with average flow are cheap; high-flow grades suit thin-wall and complex structures and cost more. High-flow CPVC needs special formulations.
Fourth, brand and origin. Imports carry a premium but offer batch stability; domestic grades offer value but uneven quality. For the same injection grade, Lubrizol costs 30-50% more than domestic — you pay for quality control and R&D.
3. Procurement pitfalls: don't let the chlorine content fool you
I have seen too many buyers end up choosing the cheapest CNY 9.5 powder after endless price comparison, only to have in-house processed pipe fail on heat resistance and crack, trigger customer returns — one loss enough to buy half a year of good material.
Procurement of CPVC is deeper water than you think. Three traps must be avoided:
First, test Vicat softening temperature and chlorine content instead of trusting the grade name. Performance of the same grade can fluctuate between batches. Test against the COA before use. Don't listen to salespeople saying "close enough" — close enough is far apart.
Second, watch out for substitution fraud. Some traders sell PVC as CPVC, or low-chlorine as high-chlorine. Demand the COA, a chlorine-content test and original packaging. Only accept material with all three.
Third, don't compare unit price alone — calculate total cost. Material A at CNY 9.5/kg costs another CNY 5/kg to process in-house and yields a 5% defect rate; material B at CNY 25/kg is ready to use and yields 1%. Per finished part, B is actually cheaper.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — you need flame retardancy AND high impact, heat resistance AND high flow, or low cost AND corrosion resistance — the problem is not CPVC itself; you don't need standard CPVC, you need modified CPVC.
Ningbo Kolong New Materials is developing high-performance modified CPVC solutions, with grades covering impact resistance, flame retardancy, high flow and corrosion resistance. For special needs, message us for a modified CPVC quote reference — it saves not only money but also trial-and-error time compared with buying powder 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.
5. Popular grades — same-day quotes via message
All prices above are references. CPVC prices change daily — chlorine, PVC resin and exchange rates all move.
If you need same-day quotes for specific grades from Lubrizol, Sekisui or domestic producers, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
For CPVC, the difference between CNY 9.5 and CNY 33 is not CNY 23.5.
Unit price is the threshold; choosing the right chlorine content and form is 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 pipe. Do the math per finished part, add in processing cost and the loss from rejects, and you will know who is truly cheap and who is truly expensive.
