Description

General

Good resistance against chemicals and impact (damage tolerant). Due to fibrilar structure, very different longitudinal and transverse properties. Fibres are linear elastic to failure. Data are for untwisted yarn.
Ultra-high-molecular-weight polyethylene (UHMWPE), high-modulus polyethylene (HMPE), high-performance polyethylene (HPPE)
