The advantage of EC Insulators
FRP Pultrusion production proess is a continous production process to produce fiberglass reinforced polymer profiles of any length length and contstant section.Reinforce-ment fibers may be roving,continous mat,woven robing,carbon or others.The fibers are impregnated with polymer matrix (resin,minerals,pigments,additives) and passed through a pre-forming station that produces the stratification necessary to give the profile the desired properties,After the pre-forming step,the resin-impregnated fibers are pulled through a heated die to polymerize the resin.
Advantage of pultrusion profile:
1 Corrosion resistant
2 Light weight and high strength
3 Anti-ageing
4 Easy maintenance
5 Excellent electromagnetism property
6 Excellent insulation property
