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。易水解PBT.A3131∞PP T710-25PBT/420SE0PA6 1500SAPA66 S223-D LCP宝理S135 BK010PPP K4835POM/S9364WS10/1570/PC K-50UVRPOM CF10PA6ˉPTF2BXXX PA6美国霍尼韦尔H35ZI PC 广州LG GP2100EVA1811PPO GX1210 TPU美国路博润S-398AS C552485PA/MXD6 1022HPBTˉX7095EVA/40WPOM PC 699PP CP53-30 PA66美国杜邦FR52G30NH NCEVA/D2044PBT 5010R5 LDPE中石化茂名828APC E2001RTPEˉ2103-90AEN PA6T 三井化学 EL630NEVA PA-561PP/BF335SA POM 美国杜邦 2 PC/ABS 台化 AC3250TPUˉ58863TPV/3939D-01TPE ST70APP F2011PCˉPC2200PA66ˉ70G35HSL
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.易水解PBT.A3131∞ PBT三菱工程5010LPP 9574E6PC/ETUV120PA66/A3WBK00464PC 5410G2-ENC2PP 6231POMSH510PA6ˉBGZ-30/2PP/M2R0C EXL1414 NA8A005TPA66ˉ66GF30GIDPA66/RF208PP/AZ564GPA/MXD6 1022H(2)PA66 PA325G6PA66ˉFE270088EVA/N1017EPDM 4021PPˉ7622MZˉABS PA-797 PMMA/0F032 PP新加坡聚烯烃FL7632PC/ABS/EF-1031POM/300ATB/TPEˉG7431-1001-00PA6/K224-TG9PPS/AR04PP/BE170MOPMMA GRANITE PC/ABS/TN-7000FPC/AL2647 PP福聚673P/HP401H POM 可隆 GF705PPˉMR30MC2 PA46荷兰D KS200PP K7726HPP/HE-362
