The materials of fiberglass extruded profiles are generally resin and fiberglass fibers, which are of high quality, followed by colorless and transparent materials, with low viscosity and low heat release function. Some characteristics of fiberglass extruded profiles are indispensable.

The produced fiberglass extruded profiles are flat and smooth, with good glossiness, high strength, and certain durability. If inferior resin is used for fiberglass extruded profiles, it will be completely opposite. The inferior resin is turbid, high viscosity, high heat release, high shrinkage, relatively slow curing, and poor compatibility. The produced fiberglass extruded profiles have many pores, are prone to cracking, and have poor strength and resistance.

Next is the comparison of fiberglass extruded profiles. High quality fiberglass extruded profiles have no significant cracks in appearance, fewer pores, bright and pure colors, good transparency, certain durability and strength, good surface smoothness, and long service life; The appearance of defective fiberglass extruded profiles has cracks, more pores, impure color, and insufficient glossiness.
