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。┯ TPU 3080A?PBT GP2300PMMAGAR PC 出光 RE1900PP RP348NLCPˉA470PMMAFT15NTAPPˉJ226TˉPBT 3720FG-NHPC/ABSNH-1037PC/ABS T-2854 PA11 法国阿科玛 7380 MAC PVC韩华EL-203M TPV 美国埃克森美孚 151-50 TPEELG BT-1028DPC 3413R GYPP B2PCˉ3030A EVA泰国石化SV1055PC/8130-10PC DX02437PA66 C6PA66 C1-N/BKPCˉKO1365PPˉ3045PC/ABS/EMI2581.4CFR TPV 美国埃克森美孚 251-80W232TPU X4985 PA66基础创新塑料AFR200YTPU/DP85786A PP晓星HJ600RAESSK30POMCF802PBTB4440G5PA6/PV00APPˉ1930L-01 PBT三菱工程5501R1 BKPP/PC366-5FEVA/N1006
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.┯ TPU 3080A?PP/HL504FBPBTˉB1505PP/KV409PPA/HA-4400MPPP/HP624J PC 德国科思创（拜耳） 2207 LDPE尤尼卡DNDV0405R LCP宝理S140M BKEVA/PX5125TPVˉ101-60W261PCˉ170C/PZ726TPVˉ24473ASA/37019PP MV00ASU PPˉ4220POMF25-0BT SK605PP BC914TF PA1010/1VX-55H/PC/4704 PPS东丽A900 ABS广州LGHI-130PMMA V920PA6 ST7301ABS AF-303EVA9318PP RG466MOPC/ABS/EMI2580.5PP H5300 电木粉 长春 T399JTPV 121-80W175PC XHT4143TPPˉM1500PC/ETUV510PC 基础创新塑料 HFD4472PMMA/249PA6ˉ6GB15LS
