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。强度PBT.3015▃PP/AZ864PA66 A 218 V30PC EXL1132PC/3500G30PA6 LS405PPS A504X95PC G-3420HTPEE EM630TPVˉ9101-65PCˉ221PC 3025NBPC 241R-111POM/PTFE KL-4540-NAT PMMA 南通三菱丽阳 VRM-40PCˉ175DPP/L12Z-01PA6 6MVHIK189A6/73M40 EVA韩华153Pˉ4020POMS9243XAP2LS HDPE中石油吉化JH***455FPPSG531FCˉ301V-6PBTˉ417PA6V30GH2.0TPE Z1050PMMAZK-M/ZK-5PP RP342N TPU WHT-1570ICPOM HS15PP/BX38APC 7103-15PP TKG-300N PA66/CM1014-V0 PVDF 吴羽 1300LCP/6330/ PP美国英力士H03G-01
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.强度PBT.3015▃PPˉH1510EVA920PC ID4-4ABS U400BPP 7633-A66/409AHS PC 德国科思创（拜耳） 1800PBT VAC3001PA66ˉRCL34PA6ˉPV007SV_YWPP/NXO21001PP GF50-10 PA66/RA341M16PC SF800ZMAS148 PA12 德国赢创德固赛 TX7389 AES 锦湖 HW610HTPC 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-X4
