POM☆原料可在-40℃~100℃温度范围内长期使用。POM☆极易分解,分解温度为280℃,分解时有性和腐蚀性气体发生。故模具钢材宜选用耐腐蚀性的材料制作。力学性能POM☆强度、刚度高,弹性好,减磨耐磨性好。
POM material can be used for a long time in the range of -40 to 100 C. POM is easy to decompose, decomposition temperature is 280 degrees, and there are excitant and corrosive gases in decomposition. Therefore, steel should be made of corrosion-resistant material. The mechanical properties are POM, high strength, high rigidity, good elasticity, good abrasion resistance.PP AH561 、2311SC PC GN-2030R2PA66 408HSPOM/K900/PC G6F23UR TPE美国埃克森美孚8211-55B100EAA/3930TPU 786SPOME3120BMTPE 5030BTPVˉ8201-90 AS(SAN)泰国朗盛C550050POM***0LVPBT/BT-2230-27/TPEE/BT-HB9242DPP KV409PPˉMX01767CˉPP/HP420JAS/XR145TPPS/9105-1PP/HP522HPA66/A402POM PDX-K-05014PBTˉ4612RPC XHT2141 GY8D046ASA S610PP/H1850PP HP527J TPU 150(粉) SURLYN美国杜邦1605EMAA/CM5023,EVA 1350VN5EMA/15024SPP H1315PBT/PET/830FPP/401-CA55PBT 414AS/GP2205PPS R-4
PBT聚对苯二甲酸***酯,又名聚对苯二甲酸四次酯。英文名;Polybutyleneterephthalate。简称PBT PBTP或PTMT,它是对苯甲酸与1,4-***的缩聚物。可由酯交换法或直接脂化法经缩聚而制得,今后的发展趋势为直接酯化法生产。PBT和PET一起被称为热塑性聚酯。
PBT poly (butylene terephthalate), also known as terephthalic acid, four methyl ester. English name; Polybutyleneterephthalate. Referred to as PBT PBTP or PTMT, it is a polycondensation of benzoic acid and 1,4- butanediol. It can be prepared by transesterification or direct esterification by condensation. The development trend in the future is direct esterification. PBT and PET are called thermoplastic polyester together.
