EP-19

EPVC Processing Additive

EP-19

EP-19 is a functional EPVC paste-grade processing additive widely used in PVC conveyor belts, tablecloths, metal coatings and hoses. It replaces 30%–50% of PVC resin, delivering excellent viscosity reduction, scratch and abrasion resistance, and moderate paste viscosity with high sag resistance.

Product Details

EP-19 is a kind of functional chemical additive widely used in PVC conveyor belts, tablecloths, metal coatings, hoses. It is used in the form of a plastisol: base resin, EP-19, plasticizer, stabilizer and filler are mixed into an EPVC paste and then shaped into plastic products. The final product offers excellent chemical stability, mechanical strength, scratch and abrasion resistance, acid and alkali resistance and easy colorability.


Main Performance

  • 1.Replaces 30% to 50% of PVC resin in PVC product producing.
  • 2.Optimized particle size distribution delivers excellent viscosity reduction, with strictly controlled volatiles ensuring product purity.
  • 3.Improves scratch and wear resistance, acid and alkali resistance of PVC products.
  • 4.Better performance in artificial leather, plastic flooring and conveyor belts, improving mechanical properties.
  • 5.The degree of polymerization is moderate, close to that of P440 resin, giving better flexibility while maintaining scratch and abrasion resistance.
  • 6.The paste has moderate viscosity and excellent sag resistance, meeting demanding mechanical requirements of leather and conveyor belt applications.
  • 7.Passed SGS testing and complies with RoHS and REACH environmental directives.
