PP多少钱一公斤?价格差三倍,差的不是十八块
PP多少钱一公斤?
这个问题一搜,从七块钱一公斤到二十五块一公斤,报价差得比熔指还离谱。有人说我买的八块的泰国石化1100NK用得挺好,有人说我买的二十块的北欧化工BEC50T30才叫真PP。到底差在哪?
说实话,问PP多少钱一公斤的人,大概率还没搞懂PP这东西不是一个料,是一个家族——均聚、共聚、无规共聚、高结晶、高流动、高抗冲,每个分支价格都不一样。你拿通用级的价和高刚性比,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,心里有个数。以下为近期市场参考价,实时价格以当日询价为准。
埃克森美孚(ExxonMobil)
7032E3,共聚高抗冲,注塑级,参考价约9-10元/公斤。电池盒、汽机车配件常用,抗冲不错,价格亲民。
7033E3,共聚高抗冲,参考价约8-10元/公斤。和7032E3是兄弟,熔指略有差异,看你工艺选。
北欧化工/博禄(Borealis/Borouge)
BEC50T30,超高分子量高刚度,参考价约12-15元/公斤。做高刚性制品的首选,贵有贵的道理。
4821,高流动高韧性透明级,参考价约13-16元/公斤。透明容器、食品包装用,透明度和韧性平衡得好。
巴塞尔/大林BASELL(LyondellBasell)
HP640R,均聚高流动高刚性,参考价约10-11元/公斤。家用器皿、食品容器、隔板,性价比之选。
6329,共聚级,参考价约8-9元/公斤。通用注塑,走量大,价格稳。
中石化(中企大厂)
K8003,共聚高抗冲,参考价约9-10元/公斤。中石化广州产,国产主力牌号,质量稳定,价格比外企同级别略低。
T30S,均聚拉丝级,参考价约7-8元/公斤。编织袋、拉丝用,最基础的PP,价格也是最低的一档。
HT9025NX,高结晶均聚,参考价约8-9元/公斤。中石化茂名产,薄壁制品、快餐盒常用。
一句话总结:通用拉丝级7-9块,普通注塑级9-12块,高刚性/高透明/特殊级12-25块。你要的是啥性能,决定了你该在哪一档选。
二、同是PP,价差凭什么这么大
PP的价格差,主要藏在四个地方。
第一,分子结构不同。均聚PP便宜,共聚PP贵,无规共聚更贵。均聚刚性好但脆,共聚抗冲好但刚性略降,无规共聚透明度高。结构不一样,性能和价格自然不一样。
第二,熔指和流动性。高熔指(高流动)适合薄壁注塑,加工效率高,价格也贵;低熔指适合挤出、吹塑,价格相对低。
第三,添加剂和改性。抗静电、阻燃、增韧、玻纤增强——这些都要加钱。你买的不是纯PP,是加了料的PP方案。
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。同样是共聚高抗冲,北欧化工比中石化贵30%,贵的是品控和研发,不是智商税。
三、采购避坑:别让牌号骗了你
我见过太多采购,比价比到最后选了最便宜的七块的,然后做出来的制品脆、易裂、客户退货,一次损失够买半年的好料。
PP采购这行,水比你想的深。三个坑必须绕开:
第一,看熔指不看牌号。同一个牌号不同批次熔指可能波动,拿到料先测熔指,和COA(质检报告)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。有些贸易商拿均聚当共聚卖,拿普通级当食品级卖。要COA、要物性报告、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8块,做出来次品率5%;B料单价10块,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——比如要阻燃又要抗冲、要增强又要高流动、要抗静电又要食品级——那不是PP的问题,是你需要的不是标准PP,是改性PP。
这时候可以看看宁波科隆新材目前在做的高性能改性PP方案,玻纤增强、阻燃、增韧、抗静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PP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。
五、常用牌号,私信给你当日报价
上面的价格都是参考价,塑料行情一天一个样,期货、原油、汇率都在动。
如果你需要埃克森美孚、北欧化工、巴塞尔、中石化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PP这事儿,七块的和二十五的,差的不是十八。
单价是门槛,选对牌号才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料,是一公斤能做出合格制品的方案。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。

How much is PP per kilogram?
PP is not one material: high-flow, high impact, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
ExxonMobil
7032E3, injection, approx. CNY 9-10/kg.
7033E3, approx. CNY 8-10/kg.
PP
BEC50T30, approx. CNY 12-15/kg.
4821, high-flow high toughness transparent grades, approx. CNY 13-16/kg. transparent containers.
PP
HP640R, approx. CNY 10-11/kg. food containers.
6329, approx. CNY 8-9/kg. general injection.
Sinopec
K8003, approx. CNY 9-10/kg.
T30S, approx. CNY 7-8/kg. woven bags.
HT9025NX, approx. CNY 8-9/kg. thin-wall parts.
2. Why prices differ so much
Four factors drive the price gap: composition or performance level, grade tier, application and brand/origin. Premium performance, special applications and imported brands all cost more; imports trade a premium for batch stability, while domestic grades offer better value.
3. Procurement pitfalls
The cheapest material often fails on performance and triggers customer returns. Three traps to avoid:
First, test key properties against the COA instead of trusting the grade name — performance of the same grade can fluctuate between batches. Second, watch out for substitution fraud: some traders pass off cheaper or recycled material as the real thing; demand the COA, a test report and original packaging before use. Third, don't compare unit price alone — calculate total cost per finished part, including rejected-goods loss; a higher-priced grade with a 1% defect rate is often cheaper than a low-priced one with 5% rejects.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — for example you need flame retardancy AND high transparency, reinforcement AND chemical resistance, or low cost AND food grade — you don't need standard PP, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PP solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PP quote reference — it saves not only money but also trial-and-error time.
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; PP prices change daily as feedstocks and exchange rates move. If you need same-day quotes for specific grades, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
Unit price is the threshold; choosing the right grade and performance is the baseline. Do the math per finished part, add rejected-goods loss, and you will know who is truly cheap and who is truly expensive.
