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。Ψ PA6 PF002 ∏PPS G531F2PA66ˉRV006ESVPA6ˉK230-HXG6PPS FZ1140-B2TPU C85APC LUX9612G AS(SAN)旭化成R27PP 7031E2 PBT荷兰R.E.K20%GF VO BK PA66杜邦FR52G30NH BK337TPV/X-4175N-04LCP/C230GI/PP/SI4351PPOˉV03550PC FL910 TPU美国路博润5714PC/ABS/T-711PA66ˉKN333G33CR PA66瑞士EMS AZ3LCP HM302POM FC-02 K(Q)胶美国雪佛龙菲利普KR-0MMA VRM-40PBTˉSK6RPOM SW-01PA66 RB00A PBT北化院303-G15PA66 70G15TPC/HN-1064IAPA66ˉS223-CPP/XM2U36PBT 3010PC L-1225ZLPC/ABS/T65PG/PP/600GPPˉQF551EˉPP 8700REVA/HS102C
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.Ψ PA6 PF002 ∏EVA3170 PPS美国泰科纳1140L4 SD3002PP 1632-01 PP C370B60PP HH450FBPPˉP9421-67727PA6ˉB3ZG6TPEE 5450TPEEˉ5550(B)ˉPC DF0049EPBT/WX96084PC L-1250ZLCP A115PBT T7331 PBT新光DF4806ABS TR-557TPUˉ1080APOM/801DEL/ HDPE陶氏DGDK-3364PP/7043L1PPS 1135A1 PC/ABS 镇江奇美 PC-550K POE瑞士陶氏PL-1880GPMMA BM-717PC LUX2114PC/HPS2 HDPELGME9180PC/PBT KU2-7940PA66 PA124PBT/5010GPN33/ PPS沙伯基础OC-1004 EMPA6/DPBM65XFM30POM/K300LO/PP/PBJ356MO PP中石油大庆Z30SPC GSH2030FTR PFA 美国杜邦 MP-501TPUˉA95K4640
