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。┇POM M270-35混炼PP/PTRC280XTPEˉ4069 ABSTECHNO400PC 401-18PA6ˉP10002EPA66/U328PPˉEP641P ETFE 大金 EP-506TPV 241-55EVA210A12/EHS HDPE泰国SCG化工H5840BPA66ˉRF00AESTPV/101-87PP 7035E5PC 1837TPU 101LGF40NATPPS/OCL36/PP AY564PBT 3015-104PA/MXD6 1022H GY553 ABS基础创新塑料DL100 BK1743UPPˉPP-180EVA/1124POMFU2015EVA VA910PPˉ1222FTPUˉ5377ATPU X585AEVAUL00328POM HP90XPP/G3U01102297PC 1695PMMAZK40 HDPE中石油吉化HC 7260PBT 5201-X10EV18161TPUˉ65AK-ESD
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.┇POM M270-35混炼 POM 旭化成 LA541TPUˉ2090APPˉP2220GNPA9T GW2458HF-1BKPP 2000E ABS LM100D1-1A5881PC/ABS CX7211 PP晓星J440XPA66 S223-DHPP 1609 PC 帝人 G-3320M BKPBTˉ2100-104B PC 基础创新塑料(南沙) EXL1434T LCP美国泰科纳L130-VF3001 TPEE东丽7277PP/6301ASA/HGMPOM N2200G5ABS Y637K TPU德国科思创（拜耳）365XPC K-30EVA15-2PA66ˉ629PC/DS0036IPBT 4012GPP HP640S PP FTP3130H-01/FTPPA66 2300MRPP 3355OPA11/BESNP40W5TLPBT/VC108 PBT东丽EC24G-30PPS A604-X95EVA 40WPC/ABS220PP 1058X PC HPS1EVA/D3030
