Braskem PE HC1828

LLDPE

Braskem

HC1828 is a Linear Low Density Polyethylene, 1-hexene copolymer, produced by gas phase process. Developed for cast film extrusion. Films obtained with this product show high load retention, outstanding puncture and tear resistance, excellent optical properties and are recommended for automatic application. It contains antioxidant additive.

Applications:
Stretch films, liners, LLDPE and HDPE blends and packages for general use.

Process:
HC1828 must be processed in cast extruder, adjusted to this polymer. The excellent conditions of processing in accordance with the type of used equipment, but the best results are gotten with 220 to 270°C extrusion temperature.
