Process Techniques

Extruding techniques

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

Screw Neck Flange Die
160℃-190℃
190℃
190℃
195℃-210℃

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.

Using

(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.
