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 GP60DE环保 PC 德国科思创（拜耳） AL2447 ABS百富化工BF-765APA6 B001PBT 1264GE30NPBTˉGK20PA66ˉRX93407DPC 8410-31TPE TF6TAAPA66/RF007SXP TPEE长春1172XLPA6/1022MT2K(Q)胶 K815PBTˉFR1PMMA IRH-50PC TLL12CUPOM F20-52ABS AG15E0 TPE荷兰DL31347A BKEPDM J-4045PBT/WX11322/TPU DP2786ADPSPA66/A218S30TPE 0201FX PA66美国杜邦135FPP 3854EVA LD-728EAA/3810EVA/UL7740 TPU美国路博润S190PP 50TD200PC S-2001RTPU R495 ETFE 大金 EP610TPU 101LGF40PBTˉ3300VSPMMAMutlicoloredPBTˉSK602PC/PBT 1731J1066
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 GP60DE环保PA66 A3WG7TPE 2400PBTˉSK643FR LDPE沙特TASNEELD 4025ASTPU/1080APBT 2184G－30TPE 6770GM TREXLINK EVA/VC590POM/LO-21/PC/ML6412AS/348Q LCP三菱工程E322G30-LMPPˉMX06404PC ML7647KPA12/1100 PC 台化 AC3600PBT/CN7000NN/BB/PP J-740EMA/SP1330PA6T RG430NA 130952TPUˉ5702FA6 V135RMPOMSC631PA66 RV007ESSPBT/B4406G6/TPEˉHX-064ANˉ HIPS巴斯夫495F BK TPV 美国埃克森美孚 9111-75TPEE HTC2751TPEˉZ6070PC/ABS/GP-5300PPˉ3155PC XRM1006PC LQ3187PP KS084PPP 2302PBTˉ1632ZPA6 V130H2.0
