Powder coatings
Nowadays, powder coating is mostly understood to be thermoset coating powder, which is applied to surfaces via electrostatic application.

For many centuries, people used natural materials as primary materials. Wood was used for building houses and ships, flax and hemp fibre were processed as ropes and technical textiles such as sails and grain sacks.
By crosslinking the polyethylene (PEX stands for cross-linked PE), a thermoplastic material can be converted into a thermoset material. This can be used at considerably higher operating temperatures, has better mechanical properties, is more stable against organic fluids and often allows thinner wall thicknesses.
For medium-voltage (MV) and high-voltage (HV) cables, the cable insulation is surrounded by a concentric, semiconductive layer on the inside and outside.
Peroxidic cross-linked cable compounds are also referred to as PEX. The process was patented during the 1960s and has been used in the cable industry since then.
The thermoset materials group, also referred to as duromers, is a group of plastics which can no longer be deformed after hardening. They are one of the three groups according to which polymers can be categorised.
Epoxy molding compounds have been known for their good electrical and mechanical properties as well as their excellent chemical and aging resistance for a long time.
