Borstar® HE3490-LS

Borstar HE3490-LS is a black, bimodal HDPE PE 100 produced by the advanced Borstar technology. The resin has the excellent performance of well dispersion, outstanding UV resistance, as well as long term stability.


Borstar 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.
