  large separation TPE, TPR is transparent, semi transparent, white, is very easy color, selection combined color powder or masterbatch color. generally lower 以SBC is TPE/TPR in color upper excellent its it type type TPE/TPR材 material. 以SBC is TPE/TPR材 material need relatively a small amount of masterbatch material can to need color 效果, but also good color ratio its it type type TPE/TPR more is pure 净, 鲜艳. attention/notes is masterbatch material viscosity need ratio TPE/TPR viscosity low, is TPE/TPR melt flow index ratio masterbatch material high, this has dispersion, make color distribution more add uniform.

一, styrene type elastomer is material TPE
usually type TPE color property can comparison excellent, is usually this category of TPE本身 color is transparent, semi transparent, 本白, 本身该 type TPE flow property also comparison good. therefore need color masterbatch, color powder can versus decrease/reduce.

1） if is SBS is material TPR, recommendation using/adopting polystyrene (PS) or EVA is color masterbatch;
2） if is SEBS is material relatively high hardness TPE, recommendation using/adopting using/adopting polypropylene (PP) is color masterbatch;
3） if is SEBS is material relatively low hardness TPE, recommendation using/adopting LDPE or EVA is color masterbatch, this can decrease/reduce is PP基 material color masterbatch 引入导致 hardness increase;

二, 以PP/EPDM组 separation thermoplastic property 橡胶TPV
versus for TPE/TPR 说, TPV color micro need ratio its use amount more 一点, and can can less 鲜艳点. usually TPV color saturated and degree more good. if Color Difference very small, recommendation need use aldehyde resin TPV, using/adopting oxidation material TPV, generally recommendation PP, PE, EVA载体 color masterbatch, especially recommendation PP基 material color masterbatch.

三, flame retardant thermoplastic property elastomer
generally separation is has flame retardant, flame retardant, flame retardant in also separation is nitrogen -磷 system flame retardant, metal hydrogen oxidation material flame retardant.

总 说, flame retardant elastomer comparison difficult color, is flame retardant elastomer in has relatively more flame retardant formed 份, color agent dispersion difficult. generally color masterbatch melt need reduce, especially difficult color flame retardant TPE, recommendation color masterbatch 载体直接 using/adopting flame retardant TPE. especially in extrusion 线缆, can can to deep color strip/profile 纹, that is color agent has dispersion 开. therefore flame retardant elastomer 建议不 need using/adopting color powder Color Matching, recommendation 直接定 made need color, or made color masterbatch.

四, 一 常规 need precautions
1） versus for extrusion grade for color requirements more high, generally lower, use color masterbatch or made;
2） need attention/notes color powder and color masterbatch drying 保存, 万一吸潮, need drying rear use;
3） usually TPE/TPR/TPV都不 can use PVC, TPU载体 color masterbatch;
4）当 use in relatively soft TPE/TPR in, need attention/notes color agent 迁移; TPV（PP/EPDM基 material ）则发生迁移 情况 need good more;
5） for/regarding high hardness SEBS基 material TPE, or 者TPV（EPDM/PP）, color powder need tool has high temperature resistance property can, is this 2 series product need relatively high processing temperature degree;
6） need most product environmental protection and related regulations requirements, 避免因 color agent has material or regulations 规定不许 can material 质.
