Polystyrene resins, other raw materials, polymers, catalysts
The main components of XPS insulation board include polystyrene resin, other raw materials and polymers, which are mixed by heat and injected with catalysts, and then extruded and pressed into the final rigid foam board.
Specific material composition
Polystyrene resin: This is the main component of XPS insulation board, which provides basic plastic structure and performance.
Other raw materials: including some additives and reinforcements, which are used to improve the physical and chemical properties of insulation boards.
Polymers: Used to enhance the overall properties and stability of materials.
Catalyst: Acts as a catalyst during the heating process, facilitating the molding and curing of the material.
Production process
The production process of XPS insulation board includes the following steps:
Raw material preparation: Polystyrene resin is mixed with other raw materials.
Heating and mixing: The mixture is heated to the appropriate temperature to allow the raw materials to melt well.
Injection catalyst: Inject catalyst during the heating process to promote the chemical reaction of the material.
Extrusion extrusion molding: The molten material is pressed out by an extruder to form the desired insulation board shape.
Cooling and curing: The formed insulation board is cooled and cured to form the final XPS insulation board.
Performance characteristics:
XPS insulation board has the following performance characteristics:
Extremely low water absorption: Due to its closed-cell honeycomb structure, XPS plates hardly absorb water.
Low thermal conductivity: It has a low thermal conductivity and has a good thermal insulation effect.
High compressive strength: High compressive strength, able to withstand large pressures.
Anti-aging: There is almost no aging decomposition under normal use.
