NBR/PVC多少钱一公斤？
这个问题一搜，从六块一公斤到三十块一公斤，报价差得比丁腈含量还多。有人说我买的六块的国产通用用得挺好，有人说我买的三十的OMNOVA高端才叫耐油。到底差在哪？
说实话，问NBR/PVC多少钱一公斤的人，大概率还没搞懂NBR/PVC这东西不是一个料——通用级、耐油级、耐寒级、耐磨级、高硬度级，每个分支价格都不一样。你拿通用级的价和耐油级比，那不叫比价，叫被忽悠。
NBR/PVC就是丁腈橡胶/聚氯乙烯合金，结合了NBR的耐油性和PVC的耐候性，常用于密封件、胶辊、电线电缆、汽车密封条、劳保手套。
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。
OMNOVA（美国）
Chemigum P83，33% ACN丁腈粉末，参考价约20-30元/公斤。PVC改性、挤出、压延、胶管、密封条。
Chemigum系列，通用级，参考价约18-28元/公斤。PVC改性、密封件、胶辊。
国产NBR/PVC（纳百川等中企）
6022A，硬度60通用级，参考价约12-20元/公斤。密封件、胶辊、电线电缆。
7022A，硬度70中硬度，参考价约13-22元/公斤。密封件、胶辊、汽车密封条。
8022A，硬度80高硬度，参考价约14-24元/公斤。高硬度密封件、胶辊、结构件。
SC-830E，丁腈粉末PVC改性，参考价约16.73-22.08元/公斤。PVC改性、密封条、胶管。
NV7030h，汽车密封用橡胶合金，参考价约18-19元/公斤。汽车密封条、电缆护套、保护套。
国产NBR/PVC（其他中企）
国产通用级，参考价约6-15元/公斤。性价比高，密封件、胶辊、电线电缆、劳保手套。
国产耐油级，参考价约10-20元/公斤。耐油密封件、胶辊、油管。
一句话总结：国产通用6-15块，国产耐油10-20块，进口通用18-28块，进口耐油20-30块。你要的是啥丁腈含量和硬度，决定了你该在哪一档选。
二、同是NBR/PVC，价差凭什么这么大
NBR/PVC的价格差，主要藏在四个地方。
第一，丁腈含量不同。丁腈含量20%左右便宜，含量50%以上耐油好但贵。丁腈含量越高，耐油性越好，但价格越高。
第二，硬度不同。低硬度（60度）便宜，高硬度（80度）适中，超高硬度（90度以上）贵。硬度决定使用场景。
第三，耐油等级不同。通用级便宜，高耐油级贵。高耐油需要特殊配方，价格更高。
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多。同样是通用级，OMNOVA比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让丁腈含量骗了你
我见过太多采购，比价比到最后选了最便宜的六块的，然后做出来的密封件耐油差、漏油、客户退货，一次损失够买半年的好料。
NBR/PVC采购这行，水比你想的深。三个坑必须绕开：
第一，看硬度和耐油等级不看牌号。同一个牌号不同批次性能可能波动，拿到料先测硬度和耐油等级，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NBR/PVC卖，拿低丁腈含量当高含量卖。要COA、要丁腈含量检测、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6块，做出来密封件次品率5%；B料单价15块，次品率1%。算到每个密封件上，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——比如要耐油又要耐寒、要高硬度又要高弹性、要低成本又要食品级——那不是NBR/PVC的问题，是你需要的不是标准NBR/PVC，是改性NBR/PVC。
这时候可以看看宁波科隆新材目前在做的高性能改性NBR/PVC方案，耐油、耐寒、耐磨、阻燃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NBR/PVC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，NBR/PVC行情一天一个样，丁二烯、丙烯腈、PVC、汇率都在动。
如果你需要OMNOVA、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NBR/PVC这事儿，六块的和三十的，差的不是二十四。
单价是门槛，选对丁腈含量和硬度才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出耐油密封件的方案。把账算到每个密封件上，再加上次品退货损失，你才知道谁真便宜谁真贵。

How much is NBR/PVC per kilogram?
Quotes range from CNY 6/kg to CNY 30/kg. NBR/PVC (nitrile rubber/PVC alloy) is not one material: general, oil-resistant, cold-resistant, wear-resistant and high-hardness grades each carry a different price.
The alloy combines NBR's oil resistance with PVC's weatherability, and is used in seals, rubber rollers, wire and cable, automotive weather strips and work gloves.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
OMNOVA (USA)
Chemigum P83, 33% ACN nitrile powder, approx. CNY 20-30/kg. PVC modification, extrusion, calendering, hoses, weather strips.
Chemigum series, general-purpose, approx. CNY 18-28/kg. PVC modification, seals, rubber rollers.
Domestic NBR/PVC (Nabaichuan and other Chinese producers)
6022A, hardness 60, general-purpose, approx. CNY 12-20/kg. Seals, rubber rollers, wire and cable.
7022A, hardness 70, medium hardness, approx. CNY 13-22/kg. Seals, rubber rollers, automotive weather strips.
8022A, hardness 80, high hardness, approx. CNY 14-24/kg. High-hardness seals, rubber rollers, structural parts.
SC-830E, nitrile powder for PVC modification, approx. CNY 16.73-22.08/kg. PVC modification, weather strips, hoses.
NV7030h, automotive-sealing rubber alloy, approx. CNY 18-19/kg. Automotive weather strips, cable jacketing, protective covers.
Domestic NBR/PVC (other Chinese producers)
General-purpose, approx. CNY 6-15/kg. Cost-effective; seals, rubber rollers, wire and cable, work gloves.
Oil-resistant grade, approx. CNY 10-20/kg. Oil-resistant seals, rubber rollers, oil lines.
In short: domestic general CNY 6-15, domestic oil-resistant CNY 10-20, imported general CNY 18-28, imported oil-resistant CNY 20-30.
2. Why prices differ so much
Four factors: (1) Nitrile content — around 20% is cheap; above 50% gives better oil resistance but costs more. (2) Hardness — low hardness (60) is cheap; high hardness (80) mid-range; ultra-high (90+) expensive; hardness decides the application. (3) Oil-resistance grade — high grades need special formulations. (4) Brand and origin — for the same general grade, OMNOVA costs 30-50% more than domestic, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often gives seals with poor oil resistance and oil leakage, causing returns. Three traps to avoid:
First, test hardness and oil-resistance grade against the COA instead of trusting the grade name. Second, watch for substitution: some traders sell PVC as NBR/PVC or low-nitrile as high-nitrile; demand the COA, a nitrile-content test and original packaging. Third, calculate total cost per seal: A at CNY 6/kg with a 5% defect rate vs. B at CNY 15/kg with 1% — B is cheaper.
4. Standard grades not enough? Consider modified compounds
If you need oil resistance AND cold resistance, high hardness AND high elasticity — you need modified NBR/PVC. Ningbo Kolong New Materials is developing high-performance modified NBR/PVC grades covering oil resistance, cold resistance, wear resistance and flame retardancy. Message us for a modified NBR/PVC quote reference.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order.
5. Same-day quotes via message
NBR/PVC prices change daily — butadiene, acrylonitrile, PVC and exchange rates all move. Message us for same-day quotes; real numbers.
Final words
The gap between CNY 6 and CNY 30 is not CNY 24. Unit price is the threshold; choosing the right nitrile content and hardness is the baseline. You are buying a solution for making oil-resistant seals. Do the math per seal, add rejected-goods loss, and you will know who is truly cheap.
