Application / Models
This foaming agent decomposes at around 150 Celsuis in rubber mixture to release useful nitrogen, carbon dioxide and a small amount of ammonia. The decomposing temperature is not high, no activator is needed to activate its decomposition, and it can decompose completely within a short time without producing unnecessary color resulting from the residual foaming agent. A small quantity of zinc oxide, stearates and stearates salt can be added to activate it decompose at a lower temperature.
The decomposition is mild relatively, 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: fine cellular in the foamed products, the time necessary for foaming and bridging will be reduced, the performance of the foamed product will become excellent, especially that the rebound elasticity will be greatly enhanced.
Same as low-temperature foaming agents, this foaming agent endows products with an adequate whiteness without adding too much titanium dioxide, which avoids affecting other physical performances of the product by adding too much white paint. The foaming agent is free of the odor characteristic of methanal generated by common low-temperature foaming agents.
As an ideal improved AC foaming agent, the medium-temperature foaming agent integrates the merits of both high- and low-temperature ones together.
This blowing agent has good storage stability under 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 with organic acids and inorganic acids.
Each 25kg is packed in international standard corrugated paper carton with a polythene liner inside.
Each batch 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.
Fujian Jinlang Fine Chemical Co., Ltd started in year 2005, which is a Hong Kong funded enterprise. It is mainly dealing in the modified AC blowing agent for EVA shoes/sheet, PVC shoes/sheet, rubber, TPR, PVC synthetic leather, PE continous foaming.
