AC Low Temperature Chemical Blowing Agent (ACP-W)

Product Introduction

ACP-W foaming agent is widely used in the foaming of EVA, PE,PVC,natural rubber, synthetic rubbers, PVC+NBR blending and other materials. It is particularly suitable to the hot-pressing molding of EVA MD in large and small molds.

Characteristics

Foaming at low temperature                   High whiteness of final products

Stable foaming ratio                                Excellent elasticity of final products

Application

The decomposing temperature of ACP-W is low, so no activator is needed to activate its decomposition. Lessen the using of foaming activator will not only reduce the cost, but avoid mottles produced. It is best fit for the production of pure white products. It could also save a large number of pigments while using in the colored products, and make the product brighter and more vivid.

The product will have fine bubble structure from using this foaming agent. The outstanding feature is that this foaming agent could produce whiter high quality EVA shoes material without affecting other physical performance of products.

It is suggested that this foaming agent should be used in lower mixed temperature and general sulfuration condition to avoid the uneven cellular, coarse cellular or other problems because of premature foamed.

In most cases, foaming activator is active oxidant, which will affects the excellent elasticity of polymer chains for EVA and other material. This series foaming agent is favor for the tensile and tearing strength of products, especially benefits to the elongation of products.

Package and Storage

Low-temperature foaming agent is odorless and non-toxic, with good storage stability. It won't decompose 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 acids or alkalis. Good local exhaust ventilation areas 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 low-temperature foaming agent is packed in an 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.
