With the diversity of people's aesthetics and the higher and higher aesthetic requirements, automotive interiors, as one of the most intuitive parts of a car, naturally receive great attention from consumers. Automotive interiors not only affect the comfort, operability, and aesthetics of the entire vehicle, but also have an important impact on the energy saving, safety, and environmental protection of the vehicle.
The polyethylene foaming material is a mixture composed of an addition polymerization resin as a basic raw material, a synthetic resin obtained through an addition polymerization reaction as a main component, and different additives are added according to different needs. Polyethylene cross-linked foamed materials can be divided into XPE (chemically cross-linked polyethylene foam) and IXPE (electronic cross-linked polyethylene foam), which play a role in automobile weight reduction, safety, beauty, comfort, energy saving, durability, etc. It plays an important role and mainly has the following unique properties:
① Low density. Can reduce the weight of the car and increase the payload.
② No corrosive effect on components and packaging, which can greatly delay the service life of equipment and products.
③ The surface is crusted, and the closed and independent cell structure has low water absorption, low thermal conductivity, and good heat insulation effect. It is a heat-insulating, sound-proof and moisture-proof business material.
④ Strong flexibility, high elasticity, shock absorption and sound insulation.
⑤ Weather resistance, cold resistance, high temperature resistance, moisture resistance, and tear resistance. Flame retardant foam has high oxygen index and good flame retardant effect.
⑥ The secondary processing performance is very good. The substrate itself can be used to compound sheets of various thicknesses, or it can be compounded with other materials into various composite materials, such as steel plates, aluminum plates and other metal materials; artificial leather, plastic films, aluminum plating. Film, woven fabric, paper and other non-metal materials are compounded into various composite materials.
Energy saving and environmental protection have become the eternal theme of the development of automotive technology. Lightweighting, comfort, energy saving, and the concept of safety and environmental protection have become the development trend of automotive products, which are increasing requirements for the performance of materials. As a highly efficient and environmentally friendly material, polyethylene crosslinked foam has become an indispensable subsidiary leading part in the field of automotive interior decoration.
