Large Gas Volume EVA Sheet Blowing Agent

Product Introduction

The high-temperature 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

The decomposing temperature for high-temperature foaming agents is over 200°C, the gas volume reaches 220ml/g (under the 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 adjusted 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, 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

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 and dry place, away 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 an international standard corrugated paper carton or fiber drum 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.

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.
