SMC sheet is an abbreviation for Sheet Molding Compound, which is made of glass fiber reinforced unsaturated polyester resin material. Featuring a three-dimensional mesh structure, multifunctional fillers, and special fiber reinforcement. Has outstanding electrical insulation performance and excellent dielectric resistance; High flame retardancy; Outstanding thermal insulation and protection performance; Outstanding mechanical strength; Strong weather resistance.

The basic types of SMC sheets are:
​
1. SMC-R: It is a random fiber sheet molding compound. The length of glass fiber is generally below 5cm, and its distribution in the resin is random. The number after R indicates the glass fiber content, for example, SMC-R50 indicates a glass fiber content of 50%.

2. SMC-C: It is a continuous glass fiber sheet molding material. What is the enhanced data for guessing; Connect the glass fibers and arrange them in a certain direction. The molding flowability in the direction of the plastic fibers is relatively low, while the mechanical strength is high.

3. SMC-D: is a directional glass fiber sheet molding compound. The reinforcement material in plastic guessing is arranged along discontinuous glass fibers with a length of 10cm or more. Because the fibers are not continuous, the molding flowability along the fiber arrangement direction is improved.
