EPVC Processing Additive
EP-17
EP-17 is a functional EPVC paste-grade processing additive widely used in non-foamed and micro-foamed artificial leather and PVC coated tarpaulin. It replaces 30%–50% of PVC resin, improving scratch and abrasion resistance, acid and alkali resistance, and reducing paste viscosity.

Product Details
EP-17 is a kind of functional chemical additive widely used in PVC products such as non-foamed and micro-foamed artificial leather, PVC coated tarpaulin, tarpaulins. It is used in the form of a plastisol: base resin, EP-17, plasticizer, stabilizer and filler are mixed into an EPVC paste and then shaped into plastic products. It offers excellent gloss, mechanical properties, acid and alkali resistance and anti-mold performance.
Main Performance
- 1.Replaces 30% to 50% of EPVC resin in PVC product producing.
- 2.Effective addition of more than 30%, with even higher addition levels achievable according to product requirements.
- 3.Improved scratch and abrasion resistance, acid and alkali resistance of PVC products.
- 4.Optimized particle size distribution delivers better viscosity reduction; better fluidity at the same plasticizer dosage.
- 5.The degree of polymerization is close to that of P440 PVC resin, giving better flexibility of the finished product.
- 6.The paste has moderate viscosity, good flow ability, low viscosity change over time and higher storage stability.
- 7.Passed SGS testing and complies with RoHS and REACH environmental directives.
