Adding foaming regulator to PVC low foaming products can promote the gelation of PVC and increase the thermal strength and elongation of the melt. Improve the surface quality of products; The tiny foams formed by foaming agents are stable and do not break the cell walls and penetrate through each other to form macropores. The resulting foam is not only small in density but also good in strength.

Product introduction

The products are mainly used for wood plastic & foamed material products, such as PVC wood plastic foamed profiles, plates, wood plastic templates, foamed profiles, foamed plates and other hard products.


25kg/ bags.


Stored in a cool and dry warehouse, and avoid rain and damp. Keep away from fire and heat source during storage. Avoid exposure to the sun, and prohibit direct contact with acid and alkali or mixed storage.

Product features
  • It can promote the plasticization of PVC
  • Vulcanization resistance: in the field of PVC door and window profiles, products using composite lead heat stabilizers are easy to pollute with sulfur and tin, resulting in blackening, while calcium zinc stabilizers will not be affected.
  • It can improve the melt strength of PVC foaming materials and prevent the merger of bubbles, so as to obtain uniformly foamed products;
  • It can ensure that the melt has good fluidity to obtain products with good appearance.
