AC234 Endotherm-exothem Balanced Blowing Agent



Product Introduction


This foaming agent is mainly used in the extruding foaming of PVC, TPR and PS for making pipes, plates, and section materials, and used in the injection molding of them to make toys and other articles.




Self-formed nucleusi

Stable performance of final products

Controllable foaming

Uniform and fine cells




This foaming agent features a good compatibility with PVC and TPR, so they will disperse evenly in the molten resins during processing to form a system with uniform phases, which in turn helps to maintain a uniform performance in the final product.


Endotherm-exothem balanced foaming agents can balance the heat generated by AC decomposition to eliminate such problem as unstable bubble holes and shrunken holes caused by the lower adhesiveness of molten resin, so that bubble holes in the product becomes uniform and dense.


The decomposing temperature of endotherm-exothem balanced foaming agents falls in the range of temperature for PVC processing, no induction term is needed for decomposition, the gas release is even and without eruption, and nuclei will be formed by themselves. These entire characteristics make the foaming process become more controllable, which guarantees the stability of performance of the foamed product with greater thickness and complex shape during the dynamic foaming process.
