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。喷漆.PMMA GR-04970≈TPV 3439DPP/RG466MOPA6 V50H2.0PMMA IRK304PP/PP-164TPUˉ75ABXPP 7620Z PC/915RPP/1102LPC/ABS NH-1027HFPPˉ6331NW PA66宇部2020B BK PP沙特巴塞尔EP548SPCˉRX2124 TPU德国科思创（拜耳）7***PE G3015TPUˉ2355-95AEPP J715M PC/NF1009F08RTPUˉT5417 PA12 瑞士EMS G21 PPO 基础创新塑料() HFM3015PA46 TS300PP/HH315MOTPU/11T65DPC HPX8REUPP H05M-00PBTˉGP1000W PP千叶化工APP-MZPA6 AN0720PC/ABS C6200-111PCˉ3025N2PA6 B3UPP UHB35MWHBPMMA HP02 PBT/ENH4530/COC 9506F-04PC VG1950
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.喷漆.PMMA GR-04970≈PC 1414T NA8A005TPA6 7331JPP AW864 PC/ABS/A35-105PC/MPXOM/WR702/ ABSUMGU400BPC/ABSCF107CTPV XL7350-92EVA/D0428EM1POM KP004APMMAMG102TPU T166 PVDF 上海三爱富 FR905PPˉ1947PBT 1200MTPU UT-85A10PC/3022U-02PA6 SX216L2V60PC DF006RXQ TPU拜耳优得U-95A10PC/ABS/LT-1APA6 BL2280-HPPS 6345L4TPV X6155NASA/CR7500TPEˉ9007PBTˉSEF-515TPC PZ715PC/PZ320G2PA6ˉK224-LG6/EPA66 A205FTPV/3700BRCOC 690RTPU U1753CPCˉDBL32 PVC大洋TH-1000(粉)PBTˉSEF-530X
