Borouge Raw Material
Polyethylene Borstar HE3490-LS
Black High Density Polyethylene for Pressure Pipe
DESCRIPTION
Borstar HE3490-LS is a black, bimodal, high density polyethylene classified as a MRS 10.0 Material (PE 100) produced by the advanced Brostar technology. Well dispersed carbon black gives outstanding UV resistance. Long term stability is ensured by an optimized stabilization system.
APPLICATIONS
Brostar HE3490-LS is recommended for pressure pipe systems in the applications field of drinking water and natural gas, pressure sewerage, relining, sea outfall and industrial. It is especially designed for the production of larger diameter, thick wall pipe, but can be processed for the whole range of diameters. It also shows excellent resistance to rapid crack propagation and slow crack growth.
