Product Introduction

JTR-H is widely used in the foaming of plastics, EVA, PE, PVC and many kinds of rubbers. It is particularly 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 cell size

No formaldehyde                                      Safe and environment-friendly

Application

JTR-H decomposes at around 160°C in EVA/rubber mixture to release useful nitrogen, carbon dioxide and small amount of ammonia. Its decomposing temperature is not high, no activator is needed. It can decompose completely within a short time and no unnecessary color resulting from the residual. A small quantity of zinc oxide, stearates and stearates salt can be added to activate it decompose at a lower temperature.

With mild decomposition, its decomposition process matches the half-time decomposition of bridging agent (DCP), so the foaming speed is same with bridging speed. All these lead to the following results: fine cellular in the final products, time is reduced in foaming and bridging. Excellent in each property of final product, especially the great enhancement on rebound elasticity.

Same with low-temperature foaming agents, JTR-M endows final products with excellent whiteness without adding too much such white paint as titanium dioxide, which avoids affecting other physical performances of the product. JTR-H is free of formaldehyde odor generated by common low-temperature foaming agents.

As an ideal modified AC foaming agent, JTR-H foaming agent integrates the merits of both high- and low-temperature foaming agents together.

Package and Storage

JTR-H has good storage stability under common temperature, but 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 organic acids or inorganic acids.

Each 25kg of this blowing agent is packed in international standard corrugated paper carton or fiber drum with a polythene liner inside.

Each batch of this foaming agent series 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.
