Brief introduction of XPS extruded board The main raw material of XPS extruded board is polystyrene resin, with an average molecular weight ranging from 170,000 to 500,000, Mw/Mn ≥ 2.6, and auxiliary materials including additives and foaming agents. Most of the blowing agents used by foreign companies do not contain halogenated carbon, but use hydrocarbon blowing agents with a faster replacement
XPS foam insulation board performance and application analysis 1. Overview Extruded polystyrene foam plastic (XPS) is mainly composed of polystyrene du vinyl resin or its copolymer. Adding a small amount of additives, it has a closed-cell structure made by heating and extruding. Rigid foam. It has excellent and long-lasting heat insulation function, unique resistance to steam penetration, extreme
XPS foam insulation board production process 1. Multi-component mixing system The fully automatic computer controls the ratio of various raw materials, adopts the weightless measurement method, and strictly compiles the mixed raw materials according to the settings, laying the foundation for the production of high-end quality products. The feeding system uses vacuum feeding to ensure the sta
Talk about some unknown advantages of XPS extruded board The full name of extruded board is called extruded polystyrene foam board, also known as XPS board. Polystyrene foam is divided into two types: intumescent EPS and continuous extrusion XPS. Compared with EPS sheet, XPS sheet is the third generation of rigid foam insulation material. It overcomes the complicated production process of E
10 advantages of XPS insulation board 1. Why does XPS extruded board not absorb water, has low thermal conductivity, and good thermal insulation effect?
