Endotherm-exothem Balanced Blowing Agent

Chemical AC Blowing Agent For PVC Foam Board

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

Characteristics:

Self-formed nuclei

Stable performance of final products

Controllable foaming

Uniform and fine cells

Application:

This series of foaming agents features a good compatibility with PVC and TPR, so they may be dispersed evenly in the molten resins during processing to form a system with uniform phases ,which helps to maintain a uniform performance in the product.

Endotherm-exothem balanced foaming agents may balance the heat generated by AC decomposition to eliminate problems such  as unstable cell holes and shrunken holes caused by lower temperature of molten resin ,so that cell holes in the product may become 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 may be formed by themselves. All these characteristics make the foaming process become more controllable, which guarantees the stability of performance of the foamed product of greater thickness and complex shape during the dynamic foaming process.

Package and storage:

This series of foaming agents is free of odor and toxicity. It allows easy storage and transportation and it is self-extinguishment. It won't decompose under common temperature but should be stored in a shady, cool and dry place away from any sources of heat, spark, open flames, or direct sunlight. Never let it contact direct acids or alkalis. Good local exhaust ventilation in mixing and handling areas is highly recommended. Be careful not to inhale its powder, make frequent skin contact or swallow it.

Each 25kg of this foaming agent is packed in an international standard corrugated paper carton or fiber drum with a polythene liner inside. Each batch of this foaming agent weighs 3 tons.

While using the foaming agent of the same batch, only a small quantity is needed to test for confirmation, and then the whole batch can be used with certainty.
