Product Details
EP-20 is a kind of functional chemical additive widely used in PVC industries such as foamed layers for resilient flooring, foamed leather, anti-slip mats, foamed floor mats, yoga mats, and foamed wallpaper. It is used in the form of a plastisol with excellent foaming properties, high-speed coating capability, acid and alkali resistance and anti-mold performance.
Main Performance
- 1.Replaces 30% to 50% of PVC resin in PVC product producing.
- 2.Effectively lowers the paste viscosity of the base resin; best effect at 30% addition, with 30%–50% addition possible according to product requirements.
- 3.High thermal stability and higher thermal decomposition temperature, resisting degradation caused by high temperature during processing.
- 4.With a degree of polymerization close to that of P450 resin, the product has good flow ability and meets the strict requirements for foaming and appearance.
- 5.Moderate paste viscosity and excellent foaming properties, suitable for products requiring complex foam structures.
- 6.Passed SGS testing and complies with RoHS and REACH environmental directives.
