WB WHITE BLOWING AGENT
Foaming agents WB1 and WB2 are medium-temperature foaming agents, mainly used to replace AC foaming agents in EVA foaming, and the residual formamide in the product is zero. It can impart uniform cells and whiteness to the product. Especially suitable for EVA transparent products .
The raw materials to produce this series of foaming agents are food-grade additives, and the gas is decomposed into CO2 and water at the same time. It has no adverse side effects on the human body and is an environmentally friendly product.
WB1 is used for expansion ratio 1.45
WB2 is used for expansion ratio above 1.7 and needs to be used in combination with OBSH.
