Evolution Sheet has a braided HT Polyester cover and lightweight braided multi-filament Polypropylene core. This construction gives added abrasion resistance and is still very flexible, lightweight and strong
Elongation is based on figures taken from tests across the diameter range, to produce an average figure.
Polyester has a specific gravity of 1.38 which means it will not float. Polyester has no strength loss when wet, it is flexible and has good abrasion resistance. Polyester fibres also have good resistance to chemicals and have a melting point of 295°C.
Polypropylene (PP), also known as Polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene has a melting point of 160 °C and the fibre floats. Various forms of Polypropylene yarns are used to produce ropes such as Split film, Yarn construction, multifilament, and monofilament each type produces a rope with different properties and uses.
