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。POMmaterialcanbeusedforalongtimeintherangeof-40to100C.POMiseasytodecompose,decompositiontemperatureis280degrees,andthereareexcitantandcorrosivegasesindecomposition.Therefore,steelshouldbemadeofcorrosion-resistantmaterial.ThemechanicalpropertiesarePOM,highstrength,highrigidity,goodelasticity,goodabrasionresistance.╮PA6F130-C2→POM德国巴斯夫W2320-00A6ˉK224-G4UTPU/2355-95AEPC/ABSGN-5001TFPA66A3WG8EVA2106EPDMSKS537-2PPM800ETPU美国泰科纳CF40-01NAPPˉMFX-1008HSPP/FRF3014/PCHP1HFPP7533TPECA3-7001PA66A3W2G6PP/MC004PC/RZ300G2PMMAVSPOM基础创新塑料KL-4030PP840NPFA美国杜邦TE9724PC/ABSGN5008LFPPˉ350LLG-202PA66AKV30GHRDUS023TPUA85P4380EVA/1641PPˉHK060AEBORFLOWPPˉ70BSPC乐天化学PC-1070PBTˉGP-5000PA6ˉC536XTLDPE卡塔尔石化FD0270PP/R12232PA66/A2LG6301PPB-M30-VTPUˉC95A10PC德国科思创（拜耳）2458PA66ˉSF6-02PBT聚对苯二甲酸***酯，又名聚对苯二甲酸四次酯。英文名；Polybutyleneterephthalate。简称PBTPBTP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。PBTpoly(butyleneterephthalate),alsoknownasterephthalicacid,fourmethylester.Englishname;Polybutyleneterephthalate.ReferredtoasPBTPBTPorPTMT,itisapolycondensationofbenzoicacidand1,4-butanediol.Itcanbepreparedbytransesterificationordirectesterificationbycondensation.Thedevelopmenttrendinthefutureisdirectesterification.PBTandPETarecalledthermoplasticpolyestertogether.╮PA6F130-C2→PA66美国杜邦450PA6BT40ZEVA/1834PPˉSJ-170TˉPPMX00619TPUDP9873DUPOMFG500MPPCˉFS2000PP/K4535PCˉDE0049PTPV3140NPOMTX-31(1.39)PCEGN2020KRPBT德国巴斯夫B4300K4PA66A3ZG7HPPBT/7195W/PPOPCN2910PP1828PA12/1111PBTˉPF391G6PP/BMU130PTFEL-5(粉)PP/W331/AS/80AS/ASAEXGY0070PA6PB340S4PBTS4090G4PPE/SA120FINPMMA560FPBT4815UHMWPEXM220PA11/BESNOP10TLPPˉPJ3040PC/ABS工程塑料EF-1000ABS美国英力士H702PPT30SPBTCE15315TPEN95555正常水草覆盖率一般为池塘水面的1/3左右。水草过密，可每隔10～15米用刀割一条宽3～5米通道，水草头保持在水面以下，割掉（防止高温水草的腐烂）。以确保有足够的受光面。7～8月，水草腐烂后应及时补充水草，以龙虾生长和蜕壳的需要。)
