There are a variety of plates, in the home decoration will be selected according to the needs of the appropriate plate, PP foam plate has its own unique advantages, is a very popular material in building materials, the following to introduce PP foam sheet, together Let's take a look at what a PP foam sheet is and what are the advantages and disadvantages.
Introduction of PP foam sheet
Pp plate is a semi-crystalline material that incorporates random copolymers, glass fibers, metal additives, or thermoplastic rubber, and is also an engineering plastic. It is characterized by low density, chemical resistance, heat resistance, impact resistance, non-toxicity, and tasteless, but its low oxidation resistance, and can not resist aromatic hydrocarbon solvents, chlorinated hydrocarbon solvents, etc. Because of its characteristics, it is widely used in the manufacture of plastic water tanks, acid and alkali-resistant equipment, environmental protection equipment, waste water, and exhaust gas discharge equipment.
PP sheet is a semi-crystalline material that is harder than PE sheet and has a higher melting point. PP sheet has good heat resistance, low temperature impact resistance, corrosion resistance and arc resistance, and ground shrinkage. It is an ideal building board in modern architecture. PP sheet is also one of the most environmentally-friendly engineering plastics. It is non-toxic and tasteless, and it is the right environmental protection.
The advantages of PP foam sheet
1, excellent heat resistance. Foaming PS is usually used at 80°C, foamed PE is only resistant to 70-80°C, and foamed PP is resistant to 120°C. The foamed PP was left at 120°C for 22 hours, and the dimensional shrinkage was less than 2%. Under the same conditions, the foamed PE contracted about 40%. Therefore, foamed PP can be used in applications where the temperature exceeds 100°C.
2, excellent mechanical properties. Take the Ace type PP foamed material of Japan Furukawa Electric as an example, its mechanical properties such as tensile strength and tear strength are in the highest grade of foam; its compressive strength is lower than that of rigid PUR and foamed PS, but softer than The PUR is high, ie it has a moderate compressive strength.
3, significant heat insulation. The foamed PP, like the foamed PE, has a closed cell structure, so its thermal conductivity is not affected by moisture. Due to its lower thermal conductivity than foamed PE and its significant thermal insulation, it can be used as an advanced thermal insulation material.
4, good resilience, and a high impact energy absorption capacity.
5, good stress cracking resistance.
6. Compared with foamed PS, no toxic gas is emitted when burning.
7, can be recycled.
PP foam board use introduction
1. The rigidity of PP is higher than that of PE, and the rigidity of foamed PP is obviously better than that of foamed PE. PP foamed sheet has high temperature resistance, good elasticity, excellent mechanical properties, and has unique advantages in application. There are different uses.
2. PP foam sheet with a density of 0.6g/cm3 has good mechanical properties, and has a very broad future in the automotive interiors. It can be used in automotive interior trim materials, high-end truck interior trim materials, and carpet support materials. Shades, acoustic panels, luggage racks, interior trims, covers, cabinets, etc.
3, the density of 0.45-0.6g/cm3 PP foam sheet has a good bending resilience, not easy to deformation, in the folder area has a broad prospect of use.
4. PP foam sheet with a density of 0.3g/cm3 has good flexibility and resilience, suitable for packaging, spacer board and other fields.
5, PP foam sheet can also be used in the field of decorative materials, processing aluminum plastic composite panels, plastic camping door, wall panels and roof panels, building modules; industrial gaskets, etc.
Summary: The above is the content of PP foam sheet and PP foam sheet that Xiaobian introduced for everyone. I hope we can help you effectively. For more information, please pay attention to this website.
