Medium Expansion Foam Extinguishing Agent

Medium Expansion Foam Extinguishing Agent

Description:

Medium expansion foam extinguishing agent has larger expansion ability than low expansion foam extinguishing agent. This foam extinguishing agent will produce exquisite medium expansion foam. And its foam quality is higher than high expansion foam extinguishing agent. So it can not only be used as high expansion foam extinguishing agent, but also cover large range of water-insoluble and flammable flowing liquid.

Product Superiority:

1. Easy to flow

2. High heat-resistant ability

3. Stable foam
