Hot Melt Extrusion
USEON can provide extruder for hot melt extrusion (HME).
Table of Contents
Basic formula
- EVA base: EVA, rosin, wax, stabilizer and additives
- TPU base: TPU (main) + others polymer (ABS/GPPS/EVA) + additives
Application
Hot melt adhesive for car window, shoes, book and others.
Process
There two process according to the viscosity of melting material:
1) If the viscosity of raw material is less than 4000CPS, it is better to use drop form pastillator system. The same system can be use for any additive material with melting temperature less than 100 degrees, such as wax, additives.
Distributor -> Belt Cooling System -> Bucket Elevator -> Packing System
2) If the viscosity of raw material is more than 4000CPS, it is better to use under water pelletizing system.
Loading -> Feeding -> Twin Screw Compounding -> Melt Filter -> Melt Pump -> Under Water Pelletizer -> Dewater -> Classifier -> Convey and Storing
