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 secondary foaming of PE.

Characteristics

Stable foaming ratio                        Large gas volume

Excellent dispersibility

Excellent mechanical performance of products

Application

Its decomposing temperature is over 200℃ and the gas volume reaches 220ml/g (under the standard temperature and pressure, called STP). Decomposition gases mainly including N₂ and CO_2, accompanied with a small amount of CO and NH₃.

The decomposing temperature can be 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, stearic acid and stearates.

This foaming agent is characterized by uniform granular size, stable foaming performance and excellent dispersibility, which makes it especially suitable for products make 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 kept in the cool and dry place and far from hot steam pipeline, fire source and direct sunlight. Never let it contact directly with acids and alkalis. It is suggested that good ventilation conditions should be realized where the foaming agent is treated and 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’ demand. 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.
