High temperature Foaming Agent

Product Introduction

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

Characteristics

Stable   foaming ratio

Large   amount of gas produced

Excellent   dispersibility

Excellent   mechanical performance of products

Application

The decomposing temperature of this high-temperature foaming agents is over 200℃ with gas volume more than 220ml/g (under the standard temperature and pressure[STP]).  Gases produced during the decomposition include mainly 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) to the foaming agent. The common activators include oxides and salts of zinc and barium, stearates and stearate salts.

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

Package and Storage

This foaming agent has excellent stability under the common temperature, but should   be stored in a cool and dry place and away from hot steam pipeline, fire source, and direct sunlight. Never let it directly contact with acids and   alkalis. Good ventilation conditions are recommended where the foaming agent   is treated or mixed. Be careful not to inhale its powder, not to make   frequent skin contact with it and not to swallow it.

Each 25kg is packed in international standard corrugated paper carton or fiber drum, depending on clients’ demand.

Each batch 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.
