Medium-temperature Blowing Agent
Product Introduction:
This series of foaming agents is widely used in the foaming of plastics, such as EVA, PE, PVC and multiple rubbers. It is particularly suitable to the hot-pressing molding of EVA shoe material in large or small molds.
Characters:
Foaming at mid-temperature
High whiteness of final products
Stable performance of final products
Uniform and fine cells
No methanal
Safe and environment-friendly
Application specification:
This series of foaming agents decompose at around 160°c in EVA/rubber mixture to release useful nitrogen, carbon dioxide and a small amount of ammonia. The decomposing temperature of mid-temperature foaming agent is not high, no activator is needed to activate its decomposition, and it will decompose completely within a short time without producing unnecessary color resulting from the residual foaming agent. A small quantity of zinc oxide or stearic acid will be added to activate it decompose at a lower temperature.
The decomposition of this series of foaming agents is mild relatively, and the process of its decomposition matches the half-time of 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 greatly reduced.
Like low-temperature foaming agents, this series of foaming agents will endow products with an adequate whiteness without adding too much white paint, such as titanium dioxide, which helps to avoid such a consequence of other physical performances of the product affected 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 together.

Package and storage:
The mid-temperature foaming agent has storage stability under common temperature. It should be stored in a cool, dry place away from any sources of heat, spark, open flames, or direct sunlight. Never let it contact directly with acids or alkalis. Good local exhaust ventilation areas in mixing and handling areas is highly recommended. 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.
Each batch of this foaming agent 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.
