Analysis of common problems of XPS extruded board 1. Why does XPS extruded plastic board not absorb water, has low thermal conductivity and good thermal insulation effect? XPS extruded board is made of polystyrene, various additives and foaming agent in the extruder, mixed, melted, pressurized, kneaded and extruded through the die, the pressure is released, the foaming agent is vaporized to
It has the characteristics of high thermal resistance, low linearity, and low expansion ratio. Its structure has a high closed cell rate, forms a vacuum layer, avoids air flow and heat dissipation, and ensures the durability and stability of its thermal insulation performance. What are the common problems of XPS extruded board on the market? What are the common problems of XPS extruded board on t
1. Overview Extruded polystyrene foam (XPS) is a rigid foam with closed-cell structure made of polystyrene resin or its copolymer as the main component, adding a small amount of additives, and extruding by heating. It has excellent and long-lasting heat insulation function, unique resistance to steam penetration, extremely high compressive strength, easy to process and install, so it has been wide

Solve the common problems in PVC foam sheet extrusion In the extrusion process of PVC foamed sheet, the problems encountered can be basically classified into four categories, one is stability problems; the second is melt strength problems; the third is lubrication problems; the fourth is dispersion problems. These four types of problems, especially the first three types of problems, will restri
Take you to understand the difference between EPS, XPS and EPP At present, the main forming foams on the market mainly include EPS, XPS and EPP, but many people do not understand the difference between them. Today Dongguan Foam Factory takes you to understand the difference between EPS, XPS and EPP: 1. EPS molding foam, also known as polystyrene foam, has the special effects of light weight,
XPS insulation board basic knowledge XPS air-conditioning insulation board is an extruded polystyrene heat insulation board. It is made of polystyrene resin plus other raw materials and polymers. It is mixed by heating and injected with a catalyst at the same time, and then extruded and extruded. The rigid foam plastic board. Its scientific name is extruded polystyrene foam for thermal insulation
