The thermal deformation temperatures of polyphenylene sulfide (PPS), chlorinated polyether, polyarylene sulfone (PAR), PEEK, POB and fusible PI can reach 240℃, 265℃, 438+00℃, 280℃ and 230℃ respectively.

Ultra-high heat-resistant plastic

A resin with a thermal deformation temperature greater than 300℃. There are several kinds. Specifically, the thermal deformation temperature of polyphenyl ester can reach 365,438+00℃, polybenzimidazole (PBI) can reach 435℃, insoluble PI can reach 360℃, polyborodiphenyl siloxane (PBP) can reach 450℃, and LCP can reach 365,438+05.

How to choose high temperature resistant plastics

1, considering heat resistance?

(1) meet the heat resistance. Don't choose too high, it will increase the cost. ?

(2) as far as possible, the use of general plastic for transformation. Heat-resistant plastics are mostly special plastics with high prices? The price of general plastic is relatively low. ?

(3) Use general-purpose plastics with high heat resistance modification as much as possible. Plastics with low heat resistance can be modified by the above modification methods, and the heat resistance modification range of different resin varieties is different. Amorphous plastics can be used as the preferred materials because they have a wide range of heat resistance improvements.
