Main component: Azodicarbonamide
Appearance: light yellow powder
Type: high temperature
Usage: EVA, PE, and PVC and rubbers
AC High-Temperature 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 such plastics as EVA,PE and PVC and many kinds of rubber, and 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 specification:
The decomposing temperature for high-temperature foaming agents is over 200°C, the gas volume no less than 220ml/g (under the standard temperature and pressure, called STP). Decomposition gases mainly including N2 and CO2 accompanies with a small amount of CO and NH3.
The decomposing temperature is adjustable within 150-200°C after adding an adequate amount of decomposing activator ( foaming promotor), common activators including Zinc, Barium oxides and salts of Zinc and Barium, stearates and stearate salts.
This series of foaming agents is characterized by uniform granular size, stable foaming performance and excellent dispersibility, which makes it especially suitable for products making under different technological conditions.

This series of 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 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 plastic lined bag, carton or barrel according to clients' demand. 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 handful is needed to test for confirmation and then the whole batch can be used with certainty.
