Product Introduction

Being an improved AC product, this foaming agent is developedbased on the high-temperature foaming agents, especially for theinjection technology of EVA. It is best fit for the injectionfoaming technology of EVA MD and EVA slippers.

Characteristics

Suitable to injection technology

Rapid and completedecomposition          

Rapid bridging setting

High whiteness ofproducts                 Smooth surface of final products       Stablefoaming ratio                          Fine bubble structure

Application

For applying this foaming agent in EVA/rubber mixture, a smallquantity of zinc oxide, stearic acid and stearate will be added tomake it decompose around 160???.

This foaming agent decomposes completely within a short time andendows the finished products with excellent performance such ashardness, density, whiteness, tensile strength and tearingstrength. It’s particularly benefits the extensibility, whitenessand better bubble structure of products.

The physical performance of this foaming agent matches thefoaming injection technology. It also has excellent technologicalperformance and dispersibility that promote flowing and bridging ofresins. The foaming agent will avoid the possible prematuredecomposition caused by high shearing during mixing and prilling,but also decomposes rapidly and completely in the mould toguarantee the product with smooth surface and fine bubblestructure, without yellow color left by AC decomposition whilemaintaining other excellent performance.

Package and Storage

Under common temperature, this foaming agent has excellentstorage stability. It should be stored in a cool and dry place andfar from hot steam pipeline, fire source and direct sunlight. Neverlet it contact directly with acids and alkalis. It is suggestedthat good ventilation conditions should be realized where thefoaming agent is treated and mixed. Be careful not to inhale itspowder, make frequent skin contact or swallow it.

Each 25kg of this foaming agent is packed in plastic-lined bag,carton or fiber drum according to clients’ demand.

Each batch of this agent weighs 3 Tons. While using the samebatch, only a handful is needed to test for confirmation and thenthe whole batch can be used with certainty.
