LDPE

Description

General

Good resistance against high temperatures and high impact. Market price regranulate 0.34 - 0.50 EURO/kg. LDPE is not or difficult to bond with an adhesive. Bonding is only possible with cyano-acrylaat after the application of a primer. With cyano-acrylaat it is not possible to bond with glass, stone and concrete.
