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 KL104 _ PP PEE137H POMHP90XPOM/W23200035LEV/PA6ˉB3WG6ˉHPPA66 RFL-4540PBT/7151G-X01/PC GSH2030KR TPV 美国埃克森美孚 8211-45 PA6德国巴斯夫B3WG6GPPPˉ7555KNE2TPV 4339DV0 TPU拜耳优得UT7-83AU10TPUˉS168DEPDM 3091PA66/LD460CPA6/BKV15W1TPE TF5TTSPA66ˉ444AHSPP/200-CA40PC/ABSH801 PA6中石化巴陵BL3280HTPV TX 5173UPOM C9021GV3/10PP/H3150TPE TF9ABAPP/1005PP/8013L1EVA/SV1040PC 基础创新塑料(南沙) 223S PP泰国HMCRC213MEVA/P1905PA66/A238PP W331 EVAUE634-04PC/AK3020POM C9021SPA66ˉRX00327PP F800E POM 宝理 M140-44
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 KL104 _ PP PEE137H SEBS美国科腾G1645MOTPU 712B ABS台化AG12A0TPE G7980TPUˉALRCL87A-VPC GS-2030MTPU WHT-6290PC 301V-10ASA821 PA66意大利LATIH2G/50TPU 585APP 5102KRTPU/5377APMMA/LG760/BV/PPO WCD891BPP 3449-01 PETG SK PN100PPS9205 PA66美国杜邦73G30L-NC010TPU 800PP PP-333TPE E3070A EVA/1070PA6 610POM 500PBKPC 3022IR(HD)PP 6501APOM N127PCˉHP2JPPBTˉKU2-724A66 SX30CW PA66美国泰科纳7523-2AMPPS/X82405APA12/LXE1095OMPM1027PC/ABS/GP-5106FPPS EW-2120GPA66 A45L
