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/ABS NH-1014具有 PA66美国杜邦FGFE5171 PC RZ300G6PC FXD141R PVC德国P70PP/7652PP/EF210AEBPP 9220PPˉ278 PA66杜邦HTNRE9078 BK507POM KEL22APA612 FE5382TPU/1170AEVA 630PC AG2530PPO LXR040C POM/PTFE 基础创新塑料 KL4030 PP/RG835MOPA6/U141/POM/UR303/PCˉIR2200PP H35Z-00PA11/MA TD525PA66 A258P1POM/FC2020D/EVA TN2006PC AZ2201TPU/1185A50VPP PF7251TPV/S-650BSTPV/123-50W175TPU 1385APOM N232000P/M2T02PA/ABS N NG-04PBT NV12PBT/1100M/PP RB4302
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/ABS NH-1014具有 PC 基础创新塑料 DP00OM S27072WS10/1570PP J-550SPPˉRP325M PA66基础创新塑料RF-7007PCˉ201-22 PPS东丽A310X04 BKPC SC2202PC/HN-3203GPA6ˉGP3300APPˉPE200NPP MF004AI PA66ˉ7020 PFA 美国苏威 PFA P450PBTˉ1401-X04 PC 基础创新塑料 LF1520AEAA/A210KEVA420 EVA韩华道达尔E180FPP AP3***PS 1140EC-SD3002PP/F219DPCˉL-1225YPA11/HX0507P/EP300KPA66/TSGZ-50PBT S7926PC/ABS MH275MPOMPM1409EVA6390 PP泰国巴塞尔EP540NPA6 8333GHIHS PMMA 奇美 CM-205EVA45D747PC AD4820PC/DFL36HL TPU美国路博润101-85DPC G-3120
