Main component: Azodicarbonamide
Appearance: light yellow powder
Particle size: 8~10 micron
Usage: PVC, TPR and PS sheet
Product Introduction:
This series of foaming agents is used mailly in extruding foaming of PVC, TPR and PS for making pipes, plates, and section materials, and used in injection molding of them for making toys and other articles.
Characteristics:
Self-formed nuclei.
Stable performance of products.
Controllable foaming
Uniform and fine cells
Application:
This series of foaming agents has a good compatibility with PVC, and TPR, so they can be dispersed evenly in the molten resins during processing to form a system with uniformity phases, which in turn helps to maintain a uniformity performance in the product.
Endotherm-exothem balanced foaming agents will balance the heat generated by AC decomposition to eliminate the problems suchas unstable cellular holes and shrunken holes caused by the lowered temperature of molten resin, so that cellular holes in the product will become equal 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 released 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 the common temperature but should be kept in the shady, cool and dry place and be kept far from hot steam pipeline, fir source and direct sunlight. Never let it contact directly acids and alkalis. Good ventilation conditions should be realized where the foaming agent is treated or mixed. Be careful not to inhale its powder, make frequent skin contact or swallow it.
Each 25kg of this foaming agent is packed in plastic lined bag, carton or fiber drum according to clients' demands.
Each batch of this foaming agent series weighs 3 tons. While using the foaming agent of same batch, only a handful is needed for testing for confirmation, and then the whole batch can be used with certainty.
