150 SRBP P1/P3 Paxolin

SRBP P1 Paper (Also known as Paxolin) is a low cost commercial quality paper based laminate and is used for low cost, low voltage installations, jigs and fixtures. It can also be used to machine templates, machine assembly plates, foundry patten plates, drilling jigs and any use that requires a tough, light weight material with reasonable electrical properties.

Thermal Insulation

Thermal Insulation is normally requested for two reasons; firstly when electrical insulation is required to work in high temperature ranges, secondly when there is need to prevent the loss of heat from a system

Electrical Insulation

Electrical insulation is chosen for its ability to resist the flow of electricity, nonconductive, it can be supplied in flexible thin films, thicker flexible laminates or rigid laminates and can be offered to suit various temperature ranges.
