1. Our Production

2. Product Description
Our Grinded Matt Surface SMC Insulation Sheet generally uses glass fibers and advanced polyester resins made with various additives and high temperatures, so the overall product performance is enhanced. The unique properties of this material solve the characteristics of wood, steel, and plastic products that are easy to age, easy to corrode, have poor insulation, and have poor flame retardancy. And our products have excellent arc resistance, and will not be easily tracked. Excellent flame retardancy enables it to work stably in continuously elevated temperature environments and maintain good electrical and mechanical properties. With a matte design, our products have more texture, and after careful grinding, our products will not have any burrs on the surface. Due to various advantages, our Grinded Matt Surface SMC Insulation Sheet is widely used as insulating structural parts in motors and electrical equipment, such as circuit breakers, switch cabinets, transformers, etc. In addition, it also has various uses in the automotive field.
It has a very high precision thickness tolerance,we can control the tolerance at plus-minus 0.1mm to meet our customer's requirments for specific industry.

2. What is a grinded Matt Surface?
A: SMC sheet surface is grinded by a grinder machine to get a more precise thickness,as processed grinded procudure,the surface of the sheet is mat and is not shiny.
3. Why does the sheet surface need to be grinded?
A: Normally the thicker SMC sheet have larger thickness tolearance,if insulation application components that processed by the sheet need a specific thickness,grinded surface process will need.
4. Do you have grinder machine and will provide this production service?
A: Yes.
5. What are the factors affecting the sheet surface?
A:The quality of insulating sheet surface is determined by many aspects, and there are many influencing factors. Therefore, for many businesses, it is not easy to produce high-quality surface sheet for a precise thickness . Therefore, in the process of production, we should pay attention to all aspects of problems. Only by considering all influencing factors, can we produce top products.
