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 TT-1065D皮包PBTˉT06202/ATPU 2363-90ATPVˉ251-85W232EVA/KE-10PP 350 PA66美国杜邦70G43LPBTˉRS1409PMMA DRT MATT PPˉ669PP/3862TPE ST70APC DF-1008EMMRTPUˉ58214PP HL001PF LCP 5244LEVA/E***2POM N2320U017UPOE/3139/LCP/E7008/PPE-185G EVA EV303 PP台塑3010PA66 1603-2NF2004TPEE/S3002PPS FZ-2100E1035PA66ˉRFL36SXSPP/HF3308C PP甘肃兰港石化H9018PA122002ES6PP HD822CF PA46荷兰D TW350PBT WF006IPC/ABS HR5007A-NPTPU TI98APTPEE/BT-2140D PA12 瑞士EMS L20LFPBT/1551GN30/POE/DKC745D
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 TT-1065D皮包POE 5371PP H5300PP AR564 PA6/PFP36PC/ABS/MP-5000A PMMA LG H1334PP/49MK40PP 7414 PA66美国杜邦73 NC010PC K2000G2PC/ABS 7210APP H270FTPU 91T85 ABS奇美PA-765 WH ABS天津大沽化工DG-FR11PP/EYC136NPP 2315SD ABS荷兰盛禧奥（斯泰隆）3416SCPA6-50 PBT基础创新塑料EXVX0125PMMACP-80TPV 4180NTPV 8221-70POM C9021GV3-30PA66/A60N01 HDPE泰国PTT化学HD2308JPP/EKC265NG51359PC 4731-8PPS/FZ-6600PA66 LD480PP RA130E-6034PC/ABS/FR3010HF/PP/BC918CFTPU LP9277PC/ABS/HI-1001BTTPVˉ2600BPP/EKG390T POM 旭化成 GN705
