BLOWING AGENT ACP/W

Chemical composition: mixture of AC, DPT blowing agents and other additives.

Features: Foaming at low temperature

Stable performance

Final products with good elasticity and whiteness

Specifications:

ITEMS	BLOWING AGENT (ACP/W)
Appearance	Faint yellow powder
Decomposition temperature, oC	132-138
Gas evolving( ml/g(@STP)	135-145
Moisture,%	0.50max
Particle size (microns)	9-14

Uses: It is broadly applied in the foaming of EVA, PE, PVC, synthetic rubber, mixture of PVC and NBR, especially for the hot pressing foaming in large or small mould of EVA MD sole.

Technical guide: ACP/W decomposes at lower temperature so no any other foaming auxiliaries need to be added. Through reducing the activating agent, the product will get a higher elongation rate.
It can provide with good foaming structure and whiter effect in EVA sole without affecting its physical performance.
It is suggested to use at a relatively low mixing temperature and normal sulfuring condition to avoid early decomposition.

Packings:25kg net cartons.
