Performance enhancement in natural and mineral filled include:

• Improved mechanical properties • Improved notched Izod and Charpy impact strength • Reduced water absorption

Adhesion as a tie layer in polyethylene based multilayer tank systems Processing Exxelor PE1040 can be added to high density polyethylene, to achieve optimum dispersion with the natural or mineral filler system and result in the best performance. Compounding parameters that lead to optimized performance include extruder type, screw design, barrel temperature, screw speed, throughput, residence time and material sequence. Our experience technical service engineers and chemists are always on hand to help you to achieve the best performance from your processing and compounding operations.
