Screw with pin
Average processing temperature as not more than 200 ° C, for extrusion processing , if there is a pin screw that kind of thing , the processing temperature needs to be further reduced ! For the hardness of Shore A60-80 flame retardant grade TPV, recommended injection molding temperatures from 170 ° C upwards beginning tune ; Shore A85-90 flame retardant grade TPV, from 180 ° C begin ! Extrusion processing , oil expeller respectively, from 160 ° C and 170 ° C begins.
Flame Retardant TPV relatively more difficult coloring , usually our only should the white and black two kinds , if you need other colors , you need to customize ! But there is a direct customer's oil refinery , it can speed up the progress of the color , but pay attention to the following questions : a) do not directly use toner , unless the customer's own re- granulation ; b) Optional masterbatch to PE or PP as the base material , and requires very good flowability and lubricity , c) the amount of added masterbatch generally in the 3-5 % .
