Feature:
1)Low water absorption rate
(2)Hard to be deformed
(3)High mechanical strength,
(4)Good electric performance wether under the moist or dry environment, Flame retardant grade could reach 94-V0,
(5)High temperature resistant,high dielectric performance and mechanical processing perfor
(6) FRP products are with low weight and high strength.
(7)Great decay resistance
FRP product has good decay resistance, it has good ability to resist to air, water and general concentration of acid, alkali, salt, and a variety of solvent oil. So, it also can be used in chemical anticorrosion to replace steel, wood and other mentals.
(8).Good electrical performance
FRP is a good insulation material, it can keeps good dielectric properties under high frequency.
Good microwave permeability, so it is widely used to make radar antenna mask.
(9)good thermal performance
FRP is with low thermal conductivity,in room temperature, it's 1.25~1.67kJ/(m·h·K), is excellent insulation material.
(10)Good plasticity
The material can be made into everything according to consumers' request
