The shrinkage of PA66 is between 1%~2%, and the addition of glass fiber can reduce the shrinkage to 0.2%~1%. The shrinkage rate is different from that in the vertical direction of the flow direction. PA66 is resistant to many solvents, but is less resistant to acids and other chlorinated agents.

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。PC GLX143、【PC GLX143】PP/TE5208PC 141RTPUˉ2103-84AENPP 3491 PA6 CM1007PA66ˉRW008XXZPA66/A3EG7FC ABS基础创新塑料MC8800 BK1005PPS/1140A1PA66ˉHK4920 PA6T 三井化学 C3000EVA 1628 PVC韩华CP-450EVA MV02528EH2TPVˉA35BUPA66ˉAKV15PBT KL1-7835PA12 TR55LXPPˉ1600DTPE VTV5LVNTPEˉ1040DN|8901PBT 553 PC/ABS 德国科思创（拜耳） FR3021 PBT南亚1410G6 GBK2EVA UE634-04 PBT北化院551-GT30SPC 4501-112PPˉ6262POM/TF301/PPˉBA66KPTFE 7A XEVA14-15POM/LKEL22A/PPˉHP400LPP S700PP G3220A PC 嘉兴帝人 G-3430HPOM FW-720F
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.
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.PC GLX143、【PC GLX143】PPˉHG313MOPBT/364PA6ˉS218V35TPU D40-70/3Pˉ48M10POM HC750PA6 BG-30S PVC钟渊PSL-31TPV/8211-45PC/ABS S3500PC ML-3110ZHP PBT宝理711SA BKPBTˉ3300LM PVC天津大沽化工P450 PETG SK JN120PP J226E EVA/3135XAPCˉ124C EXL1414TPC/ABS GP5006BPCˉ302-06TPU/C78A PC 三菱工程 SD101G10TPUˉ54620TPU/52P/TB71STPU UB410BPA66 RFB66PP M1500PP/PPH343T4POM K100HSLOPOM FU2015PA12L2140LCPˉT130TPE TC3CHTEVA LV266PPˉHJ060UBPP/HF400
