Improved White Powder PVC Environmental Blowing Agent

Product Introduction

This foaming agent is mainly used in the foaming extrusion and injection technology of PVC, TPR, PP and PS for profile materials, plates and sheets to make all kinds of low-foam plastic products, such as shutters and photo frames etc.

Characteristics

No scale formed on the screw                             Controllable foaming

Excellent whiteness of final products                   Uniform cells

Smooth surface of final products

Application

This foaming agent is solid and easily flowing white powder. The residue left after its decomposition is pure white and won’t affect the color of final products.

It possesses a good compatibility with PVC, TPR and PS, which will be dispersed evenly in the above molten resins to form a uniform system in processing. Meanwhile, this foaming agent contains cellular regulator to make cellular in the foamed products become fine and even, and this will maintain uniform performance in all parts of the product.

This foaming agent is made of food grade adjutant, its decomposition gases are N2 and CO2 that would not corrode equipments and won’t do any harm to the human body. It is an environment-friendly product.

This foaming agent is an endothermic foaming agent, without induction term and the decomposition is completed stepwise. No eruptive decomposition will happen, so cellular in the molt resin will grow evenly and steadily in the processing, won't break or overflow over the product surface to affect the product quality. All these endow final product with excellent traits on uniform cells and smooth surface.

Package and Storage

This foaming agent is odorless and non-toxic, with good storage stability and has self-extinguishment. It won't decompose under common temperature but should be stored in a cool, dry place away from any sources of heat, spark, open flames, or direct sunlight. Never let it contact directly with 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.
