tough rigid TM flame retardant grade TPV processing precautions
因 is tough rigid TM flame retardant grade TPV in has 约30% flame retardant, therefore its processing process and TPV has different, below/following is need attention/notes several 方面:
1） tough rigid TM flame retardant grade TPV processing front drying
processing front need drying, drying conditions is 100°C/2 small 时, drying is to 位, can products table/sheet and products 截面, if table/sheet coarse and upper gas 孔, 则说明 also need 进一步 drying. 当时没 use flame retardant TPV, need 密封储存, lower use still need drying!
2） tough rigid TM flame retardant grade TPV processing temperature degree
generally processing temperature degree amount need ultra- 200°C, for/regarding extrusion processing, if screw has 销钉之 type 话, processing temperature degree also 需进一步 reduce! for/regarding hardness is 肖A60-80 flame retardant grade TPV, injection molding processing temperature degree from 170°C往 upper 开始调; 肖A85-90 flame retardant grade TPV, from 180°C开始! extrusion processing 话, separation from 160°C and 170°C开始.
3） tough rigid TM flame retardant grade TPV color
versus for flame retardant grade TPV color comparison difficult, usually 我司仅 supply and black 2 types, if need its it color, need made! has 客户自己直接 Color Matching 话, can add fast Color Matching degree, need attention/notes below/following issues: a)不直接 use color powder, remove non 客户自己 heavy new pelletizing; b) selection color masterbatch 以PE or PP is material, and need versus good flow property and lubricated property can, c) color masterbatch add amount generally need in 3-5%.
