High Temperature Modified Blowing Agent for Rubber/Plastics

Product Introduction

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

Characteristics

Stable foaming ratio

Large gas volume

Excellent dispersibility

Excellent mechanical performance of final products

Application

Its decomposing temperature is over 200°C and the gas volume reaches 220ml/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 can be adjustable within 150-200°C after adding an adequate amount of decomposing activator (foam-promoting agent), common activators including Zinc, Barium oxides and salts of Zinc and Barium, stearic acid and stearates.

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

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 directly contact 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.

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

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