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。PP H11G-00 √ PP PEF040AE TPE G7410-1000-00 ABS锦湖750SHPP PP-333JEVA 3135XPA12/LX9112PA66ˉN-201 PPO 三菱工程 AN45ABS HI-121PA6ˉLS285PBT/ENH4550PCˉ280P V30GPCˉ3022RLCP E471i PA66美国杜邦54G15HSLR PP/KPG1030EVA 1880A PA66上海罗地亚***H1 PA66荷兰D S225-KSTPE TC5CSNPA66ˉ1500PPˉRX-13000 PA46荷兰D HF4130ASA/36609 PC 基础创新塑料(西班牙) 945A-116PP/PTYC900POM SF-15PPˉ3276ˉTPU 982SU PC/DE003ZPA6V30W1 PBT新光DF4806PPˉF401PA9T TA124PP 13712 PP AS23K(W)-06/Surlyn?/1825//POM/***0-71/
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.PP H11G-00 √ PP PEF040AE PPˉBA742ECˉPP/9310PC/121MEMAA/CM5023，PA6ˉV50H2.0PC AC2820-AEPP/MX00709PC/ABSCX1440TPU/DP3868DEVA/3190PCˉ8310-22 PC 新加坡帝人 LN-1250GPPO WCD933 PP/7693 PP台化K9017PC GN1000FALCP LC-5050GCF TPUˉGP92AEPA6ˉF232PCˉML-3210ZHPTPV A80BIPOMFG500TL PC LG SR-3108FC WL22PPA66ˉRX09411HABS PA-709PBTˉ4830-BKPCˉSLX2071TPC/ABSFR630GRPP/BX36AEVALD312.09PPˉ3225 PMMA 英国璐彩特 CP-51AEVA 28-05EVA/393PˉQB510APC/9125PA12/AZM/2C/ABS TMB4312
