Heat resistance index and classification of plastic profile products shared by Customized Plastic Products Supplier.
Plastic profile products and metal, ceramics, glass and other traditional materials, one of the shortcomings of plastic heat resistance is not high, which often limits its use in high temperature occasions. In plastic materials, different kinds of plastics have different heat resistance. Some are very low in heat resistance, others are higher. Heat resistant plastic is generally refers to the thermal deformation temperature in 200℃ above a class of plastic products. The indexes to measure the heat resistance of plastic products are heat deformation temperature, Martin heat resistance temperature and vica softening point, among which the heat deformation temperature is the most commonly used.
The relation of the above three heat resistance indexes of the same kind of plastic profile products is as follows: > heat deformation temperature > Martin heat resistance temperature at the softening point of vica.
Extrusion and Injection Plastic Profiles
According to the heat resistance of plastics, they are divided into the following four categories:
1. Low heat resistant Custom PE Plastic Extrusion Profile thermal deformation temperature is less than 100℃ of a class of resin. Specific varieties: PE, PS, PVC, PET, PBT, ABS and PMMA.
2. Heat resistant plastic thermal deformation temperature in 100 ~ 200℃ between a class of resin. Specific varieties are: PP, PVF, PVDC, PSF, PPO and PC.
3. High heat resistant plastic thermal deformation temperature between 200 ~ 300℃ a class of resin. Specific varieties are: of polyphenylene sulfide (PPS) thermal deformation temperature is 240 ℃, heat distortion temperature of the chlorinated polyether can reach 2 l0 ℃, aromatic sulfone (PAR) of the thermal deformation temperature can reach 280 ℃, thermal deformation temperature can reach 230 ℃, PEEK POB thermal deformation temperature can reach 260 ~ 300 c, thermal deformation temperature of the fusible PI for 270 ~ 280 ℃, amino plastics thermal deformation temperature of 240 ℃, thermal deformation temperature can reach 230 ℃, EP PF thermal deformation temperature is 200 ℃.
4. Ultra-high heat resistant plastic thermal deformation temperature is greater than 300℃ of a class of resin. There are few kinds of them, such as: the Plastic Injection Profiles thermal deformation temperature of polyphenyl ester can reach 310℃, the thermal deformation temperature of polybenzimidazole (PBI) can reach 435℃, and the thermal deformation temperature without melting PI can reach 360℃.
