Application of PVC processing auxiliaries

- Jun 26, 2017 -

PVC belongs to a brittle polymer material, which restricts the application and further development of PVC. Therefore, the modification of PVC to obtain high-strength, high toughness of PVC composite material is of great significance, PVC toughening is now mostly mixed with ductile materials, the main way: CPE, MBS, ACR, SRC and other elastomer materials.

Because CPE molecules containing double bonds, has good weather resistance, low cost, excellent performance, wide application range, therefore, from the middle of 50s industrial production has got much attention in many countries, the United States, Japan, Germany and other countries to achieve high-volume, multi performance and multi variety production, since CPE is still in developed countries one of the main varieties of application of impact modifier.
