what is TPEE

TPEE  separation in hard is polyester, soft is Tg  value low polyether or polyester, is more 嵌 段 copolymer.

    TPEE 依 separation 子构造之 different can separation is:

    1)  polyester, polyether type: hard is 芳香系 crystallization property polyester, soft 质段则 is polyether

    2)  polyester, polyester type: hard is 芳香系 crystallization property polyester, soft 质段则 is aliphatic polyester

    3)  liquid type  TPEE: hard is rigid liquid separation 子, soft is aliphatic polyester.  

     above types TPEE  in, most commonly used demand amount most more is polyester, polyether type  TPEE, hard 质段以 PBT  is table/sheet, butanediol and acid ester formed formed, soft polyether 则以 PTMG is table/sheet. 因 PBT  tool heat resistant type, crystallization speed degree large, 而 PTMG 则 tool low 玻璃移点 Tg, types  TPEE  molding property excellent, has balanced material property and high heat resistant property.

    as is hot can elastomer, TPEE   can its machine can scope/range is high hardness scope/range. in low hard   degree scope/range, long small （3  below/following ）, hard 质段会 solvent understanding in soft in in in 间层,   therefore micro versus separation 離不完 full, 也就无 method tool full elastomer machine can, 故TPEE 之 low hardness made   product easy obtain.

 TPEE chemical structure:

    TPEE  in property can and processing process upper has below/following main features:

     advantages:

    heat resistant property most high, resistant heavy large, elastic property high

    反复疲勞 features excellent property strong/high tough

    low temperature property relatively  TPU  more 佳

    oil resistant / resistant product / chemical resistant solvent agent property 佳

     disadvantages:

    easy obtain low hardness manufacturing

    processing conditions relatively narrow, must relatively precision processing machine

    price 昂贵

Hytrel.TEEE命名规则

Hytrel. high property can and general purpose grade full 部以四位数命名原则命名, 典 type general purpose grade is in front add G . front 两 数字代 table/sheet Shore D hardness. 第三 数字代 table/sheet versus for degree in same hardness and and other grade inner. 例如, if comparison G5544, 5526, and 5556, hardness full is 55D . 而G5544 is general purpose grade 别. in 5526 and 5556 between , 5526 has more low melt or more high flow property. 第四 数字 table/sheet stability property type type : 0-5 变 color and 6-9 不变 color.

专业 and other grade , 当 add front 缀HTR, according to 连续数字 system 命名. 否则, 遵循 upper 述命名原则.

¡Hytrel.. 3078.- most soft grade 别
¡. HTR6108 has most low property
¡. 5555HS 添 add hot agent combined used for high temperature ring 境
¡. HTR8068 is has Hytrel. grade in 唯一 UL V-0 and other grade   .

blow molding grade full is black 命名也 according to 连续数字 system.

DYM and other grade is full 部染黑 , and 数字代码代 table/sheet polymer flexural modulus according to ISO178 standards in room temperature , MPa lower 测. 因而DYM100BK ratio DYM350BK more tool has tough property.
