Fiberglass extruded profiles have excellent electrical insulation, no electromagnetic properties, and electric sparks. They can be used in areas with conductive hazards, sensitive to magnetism, as well as flammable and explosive places.

Pultruded profiles are a type of insulation material with a much lower coefficient of thermal expansion than general plastics. Pultruded profiles have excellent mechanical properties at low temperatures and will not melt at high temperatures. However, their strength and modulus will decrease to a certain extent at high temperatures. Generally, the applicable temperature range for extruded profiles is -50 ℃ -100 ℃!
