Special EVA Injection Processing Blowing Agent

Product Introduction

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

Characteristics

Suitable to injection technology

Rapid and complete decomposition

Rapid bridging setting

High whiteness of final products

Smooth surface of final products

Stable foaming ratio

Fine cell structure

Application

For applying this series of foaming agents in EVA/rubber mixture, a small quantity of zinc oxide, stearic acid and stearate will be added to make it decomposes around 160°C.

This foaming agent decomposes completely within a short time and endows the finished products with excellent performance such as hardness, density, whiteness, tensile strength and tearing strength. It’s particularly benefits the extensibility, whiteness and better cell structure of final products.

The physical performance of this foaming agent matches the foaming injection technology. It also has excellent technological performance and dispersibility that promote flowing and bridging of resins. The foaming agent will avoid the possible premature decomposition caused by high shearing during mixing and prilling, but also decomposes rapidly and completely in the mould to guarantee final product with smooth surface and fine cell structure, without yellow color left by AC decomposition while maintaining other excellent performance.

Package and Storage

Under common temperature, this foaming agent has excellent storage stability. 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 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 barrel with a polythene liner inside.

Each batch of this agent weighs 3 Tons. While use the same batch, only a small quantity is needed to test for confirmation and then the whole batch can be used with certainty.
