  PVC foaming regulator TG-90 is independently developed by our company, it is ultra-high molecular weight polymer with multi-layer structure. It is the polymerization of acrylate monomers by multistage emulsion polymerization and is widely used in PVC extrusion low foaming products. And various technical indicators have reached the level of similar products abroad.

  I. Physical and chemical properties

  The product is white flowing powder, the bulk density of it is 0.40-0.50g/cm3, it is insoluble in water or ethanol, but soluble in chloroform.

  II. Application features

  The addition of foam regulator into the PVC extrusion low foaming products can promote the gelation of PVC and improve the thermal strength and extensibility of the melt and the surface quality of the product. The small bubble hole formed by the foaming agent is stable, and the wall of the bubble wall will not burst and penetrate each other to form a large hole. Thus, the bubble not only owns small density but also has a good strength.

  The product is mainly used for PVC extrusion low foaming plate, pipes, and profiles, and the K-125, K-400, PA-30, P-530, PA-828, 20F and other similar foreign products can be substituted by it. The actual application effects are as follows:

(1) To obtain good surface quality

(2) Strengthen the elasticity of processing

(3) Low density

(4) Improve the processing speed and increase economic benefits
