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 C70AWH喷漆PBTˉ330GWEVA/H900WPCˉ170OM/KL003LH/ PA12 美国EMS D1330A GFPC/ABS/GF20PPO PX2949 PA66基础创新塑料(南沙)RF00AS-BKPBTˉSK612SFPP H3400 GPPS江苏赛宝龙GP525PPE/SE1PP/PM200EVA E182LTPE SE-150AN PA46荷兰D TC155TPU K-590APP 4108PBT/PDR4922EVA VA800PETG GN046PA6ˉKN133G25PA123035JUC FXD923APP F2011TPUˉDP8795A-S04BT 3015-104PPˉ1127NˉPPS A575W20PBT 1100-630SPC/DX89795ASA/S757RTPEE 5556WPBT/PET/8032UXTPU D198K PC 帝人 9920TPE/DGR6370NCTPU 1185AWM
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 C70AWH喷漆PA6 8232GHSEAA/3340PC/ABS 1-1427PC FLLS2CPPPˉT2502EMA比利时杜邦12024PC/D2000ITPVˉ121-58W175PA6ˉPF003UAS/80AS/PP/10642TPU 195ARPMMADRM PPO 旭化成 540ZPA6 1010F5PA66/SX30CWEVA/1181EVA PV1400PP R801PA11/BESNP20NOIRTLPMMA4490 PP惠州南亚3117 ANC1PETG MP002TPU/WY1157PA66ˉA3ZPE/PO5300HPPE-14526-31PP HJ800RPA6 F236-CPCˉ1-937A12/X739A66 AG-30LF15PPS/OCP36A/PC/ABS/BM-1008PBTˉ5010N6-3XPBTˉ300FPPOMSlide2404PA66/S223-HG6
