Application
|
ACP-W with low decomposing temperature, 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.
Suggest to use ACP-W 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
|
It is odorless and non-toxic, with good storage stability and 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 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 plastic lined bag or carton according to clients’ demand.
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.
