DSM stock large quantities of elastic shockcord in 2mm diameter to 14mm diameter. These cords have either Polyester or Polypropylene braided covers and are available in many different colours. Our purpose built factory in Stourport-on-Severn manufactures many different types of shockcord assemblies including:
Rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called “tapping”. The latex then is refined into rubber that is ready for commercial processing.
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.
