Product Introduction

This foaming agent is produced after   ultra-fining treatment and surface denaturing. It is used widely in the   foaming of plastics for EVA,    PE, PVC and many kinds of   rubber, and it is suitable to hot-pressing foaming in large or small mold and   secondary foaming of PE.

Characteristics

Stable foaming ratio

Large gas volume

Excellent dispersibility

Excellent mechanical performance of final   products

Application

Its decomposing temperature is high and the   gas volume reaches 210ml/g (under standard temperature and pressure, called   STP). Decomposition gases mainly including N₂ and CO₂  accompanied with a small amount of CO and NH₃.

The decomposing temperature is adjustable  within 150-200℃ after adding an adequate amount of decomposing   activator (foam-promoting agent), common activators including Zinc, Barium   oxides and salts of Zinc and Barium, stearates and stearate salts.

This foaming agent is characterized by  uniform granular size, stable foaming performance and excellent   dispersibility, which makes it especially suitable for products making under   different technological conditions.

Package and Storage

1. 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.

2. Each 25kg of this foaming agent is packed  in corrugated paper carton with a polythene liner inside. A slight sticky to  the hands in using is the property of AC series of foaming agent, not caused  by dampness and won’t affect its quality.

3. Each batch of this foaming agent series  weighs 3 Tons. While using the foaming agent of same batch, only a small  quantity is needed to test for confirmation and then the whole batch can be  used with certainty.
