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。╘ ASA TW21H ○PMMA/ST35G8PC PCSP0019 PPPMG3FTA HDPE台塑8003 PC 三菱工程 H3000RPA66 FR200PBT ENH3500PC FU4007 PBT宝理515AC ED3002TPUˉ2363-55DASALI913EAA/A221MPOM GH-25EVA LD727.22 ABS中石油大庆755APA6ˉDPBM29XH2.0EFPP/40YM243TPU D16N98UVPPˉH07B-01 SIS美国科腾D1119PPA66 S3CTPEE/447PBT/HX420HPC/TPU DP89043DPP/8224E1PA66ˉRV00CEXPEVA/210ET POM 工程塑料 ET-20APBT 5710GT30-X4TPUˉK-787APP 3716 PP BC3APA66 RFM62PP H28E-00POM/4513/PA6ˉV35H2.0PPO PCN2615PA6/HI1102A
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.╘ ASA TW21H ○PC 191PBT RS1421PCˉSLX2271TPA6 B35FAPC SR-3108L POM N2650Z6 PP沙特570 PA66旭化成LC020EBA/3717EVAUE624000PA12SH0700BTPVˉ2645TPU 2103-90AEFHPPˉ786ˉPP JC-160PA66/S223-G4U PA66漳州长春21G5-201PPˉ1453ˉPP/J707GTPU C75A15HPMTPVˉX5725B PA46荷兰D IG-S253F7PA11/MB3504HPPPS GS-40-11/12 PP荷兰利安德巴塞尔EC340QPBT/GP2300/PBT/PF801/PBT 3318PP K1001POM/FC2020H/PP/QF551APPˉ1043NPA6ˉLS280PP TRC221PO/FXN2090HPPˉ6600APP/-530TPVˉ103-50
