Process Techniques

Extruding techniques

The recommended setting temperatures for each zone of the extruder are as follows:


The above temperature is reference temperature, due to equipment differences, screw compression ratio difference, customer should choose suitable temperature according to their own equipment condition.


(1) A material must be used up within 24 hours after open the bag.

(2) Catalyst can be use normally after drying if package slight damage. Drying condition:70-75 ℃, 2.5-3hours.

Packing, Storage & Transport

1. Packing: A material: 23.75kgs/bag, B material: 1.25kgs/bag

2. Transport requirement: Keep away from the sunshine, rain and soaking during transport, as well as handle gently during carrying.
