What are the thermoset insulation materials?
Clicks: 【501】 Date: [2017/1/11 20:05:36]

The insulation material can collect excess heat, release it in a timely and stable manner, with small gradient changes, and effectively reduce the amount of loss. Room temperature can reach, and winter insulation can play a balancing role. Today, I will tell you what the thermoset insulation materials are.

From the comparison of heat resistance, in general, thermosetting insulation materials encounter carbonization, non-melting, and no molten drips when exposed to high temperatures or open flames, while thermoplastic insulation materials encounter high temperatures or open flames, foams shrink and melt, and there is melting during combustion Drops are generated.

Although thermosetting and thermoplastic insulation materials have different molding processes, they are both organic insulation materials. Such as: common thermosetting insulation materials are phenolic foam, polyurethane rigid foam, and common thermoplastic insulation materials are polystyrene foam (EPS, XPS).

Among them, phenolic foam is an ideal thermosetting insulation material. The combustion level of phenolic foam is B1-A, and the general polyurethane rigid foam is B2. The flame retardant can reach B1, and the price is expensive. 40kg / The price of m3 phenolic board is only 400 yuan / m3, which is only slightly higher than XPS and EPS. The flame retardancy advantage is very large.
