Top quality Odorless Medium temperature Foaming Agent (JL A)

Product Introduction

This foaming agent is widely used in the foaming of such plastics as EVA,  PE, PVC and many kinds of rubbers. It is particular suitable to the hot-pressing molding of EVA shoe   material in large or small molds.

Characteristics

Foaming at medium temperature

High Whiteness of final products

Stable foaming ratio

Uniform and fine   cellular

No methanal or ammoniac odour

Safe and environment-friendly

Application

This foaming agent decomposes at around 150℃ 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.
