PPA manufacturers
PPA(polymer processing agents) are additives used to improve the processing characteristics of the polymer. PPA is used in a wide range of products and industries including but not limited to automotive, appliances, consumer goods, packaging, and medical devices. The main performance characteristics of PPA are：
1. Reduces viscosity and improves flow properties
2. Enhances thermal stability and processing efficiency
3. Increases output and reduces die build-up during extrusion
4. Improves surface quality of molded parts
