Main component: Azodicarbonamide Appearance: light yellow powder Usage: EVA,PE,PVC and multiple rubbers, EVA shoe material
Medium-temperature Blowing Agent
Products Introduction:
This series of foaming agents is widely used in the foaming of plastics, such as EVA,PE and PVC and multiple rubbers. It is particularly suitable for the hot-pressing molding of EVA shoe material in large or small molds.
Features:
Foaming at mid-temperature
High whiteness of final products
Stable performance of final products
Uniform and fine cells
No formaldehyde
Safe and environment-friendly
Application specification:
This series of foaming agents decomposes around 160°c in EVA/rubber mixture to release useful nitrogen, carbon dioxide and a small amount of ammonia. The decomposing temperature isn't high, no activator is needed to activate its decomposition. It decomposes completely within a short time without producing the unnecessary color resulting from the residual foaming agent. Or add a small quantity of zinc oxide or stearic acid to activate it decompose at a lower temperature.
The decomposition of this series of foaming agents is mild, and its decomposition process matches the half-time decomposition of bridging agent (DCP), so that the foaming speed will match the bridging speed. All of those lead to the following results: cells in the foamed products will be fine, the time necessary for foaming and bridging will be reduced greatly, each physical properties of products is excellent, especially a great improvement on resilience.
Same with low-temperature foaming agents, this series of foaming agents can endow products with an adequate whiteness without adding too much titanium white or other white paint, which helps to avoid affecting products' other physical performances by adding too much white paint. This series of foaming agents is free of the odor characteristic of formaldehyde generated by common low-temperature foaming agents.
As an ideal modified AC blowing agent, the mid-temperature foaming agent integrates the merits of both high-and low-temperature foaming agents together.

Package and storage:
The mid-temperature foaming agent has excellent stability when stored under the common temperature. It should be stored in a cool and dry place, away from hot steam pipeline, fire source and direct sunlight. Never let it contact directly organic acid and inorganic acid.
Each 25KG of this series of foaming agent is packed in international standard corrugated paper carton or fiber drum with a polythene liner inside.
A batch of this series of foaming agent weighs 3 tons. While using the agent of same batch, only a small quantity is needed to test for confirmation, and then the whole batch can be used with certainty.
