         and metal, 陶瓷, and other 传统材 material versus ratio, plastics disadvantages is heat resistant property high, this 往往限 made its in high temperature combined use.

         in plastics material in, different product types plastics resistant thermal properties different; has heat resistant very low, has relatively high. heat resistant type plastics generally is heat deflection temperature (HDT) in 200℃ above type plastics products.

        衡 amount plastics products resistant thermal properties good bad indicators has heat deflection temperature (HDT), heat resistant temperature degree and soft 化点三 types, its in heat deflection temperature (HDT) most is commonly used.

        同一 types plastics upper types heat resistant property indicators 关系如 lower: soft 化点> heat deflection temperature (HDT) >马丁 heat resistant temperature degree

        按 plastics heat resistant property large small will plastics separation formed lower type:

        ① low heat resistant type plastics heat deflection temperature (HDT) small 于100℃ 一 type resin. specific product types has: PE, PS, PVC, PET, PBT, ABS and PMMA and other.

        ② in heat resistant type plastics heat deflection temperature (HDT) in 100～200℃ between type resin. specific product types has: PP, PVF, PVDC, PSF, PPO and PC and other.

        ③ high heat resistant type plastics heat deflection temperature (HDT) in 200～300℃ between type resin. specific product types has: polyphenylene sulfide (PPS) (PPS) heat deflection temperature (HDT) can 达240℃, chlorine polyether heat deflection temperature (HDT) can 达2l0℃, poly 芳砜(PAR) heat deflection temperature (HDT) can 达280℃, PEEK heat deflection temperature (HDT) can 达230℃, POB heat deflection temperature (HDT) can 达260～300C, can 熔PI heat deflection temperature (HDT) is 270～280℃, plastics heat deflection temperature (HDT) is 240℃, EP heat deflection temperature (HDT) can 达230℃, PF heat deflection temperature (HDT) can 达200℃.

        ④ ultra-high heat resistant type plastics heat deflection temperature (HDT) large 于300℃ 一 type resin. its types type very less, specific has: poly ester heat deflection temperature (HDT) can 达310℃, polybenzimidazole (PBI) (PBI) heat deflection temperature (HDT) can 达435℃, 不熔PI heat deflection temperature (HDT) can 达360℃.

         that most high temperature resistance is types?

         polybenzimidazole (PBI) PBI long as temperature degree can 达310℃, short use temperature degree can 达500℃, polybenzimidazole (PBI) PBI is currently most high temperature resistance plastics 之一, is price is plastics price most high, but also processing has difficult degree. therefore, most high temperature resistance plastics is polybenzimidazole (PBI) PBI.

         its 次, most high temperature resistance plastics is polyimide (PI) PI, long as temperature degree can 达290℃ left right, short can 达480℃, can in -240℃ ring lower as.

         its it high temperature resistance material

         polyamide (PA) amine PAI(also 称TORLON), is types hot solid property plastics, long as temperature degree can 达250℃, low temperature resistance property can 也同样出 color, TORLON meanwhile tool has excellent wear resistance can and impact resistant property can.

         polyether ether ketone PEEK, long as temperature degree can 达160℃, short as temperature degree can 达260℃, reinforcement grade high temperature resistance property can more 佳.

         polyetherimide (PEI) PEI, long as temperature degree can 达170℃, short as temperature degree can 达200℃.

         polyphenylene sulfide (PPS) PPS long as temperature degree can 达220℃, short as temperature degree can 达260℃.

         poly fluorine ethylene PVDF long as temperature degree can 达150℃, short as temperature degree can 达160, meanwhile tool has excellent corrosion resistant property can, and tool has relatively high machine strong/high degree and rigid property.

         PTFE PTFE long as temperature degree can 达260℃, short as temperature degree is 280℃, tool has excellent corrosion resistant property can, 俗称“ plastics 王”. also tool has low friction coefficient.

         polysulfone (PSU) PSU long as temperature degree 150℃, short as temperature degree can 达180℃, polysulfone (PSU) PSU also has very good comprehensive electrical property can. PES property can and PSU similar, as temperature degree more high, long as temperature degree 180℃, short 期220℃.

         nylon 46, long as temperature degree can 达135℃, tool has excellent tough property and good chemical resistance.
