Here at Friend Group, we offer two major products, namely insulation laminate materials and composite materials.

Our insulation products are pressed and cured from insulating resins and some reinforcements such as fiber paper, cotton cloth, glass cloth, etc. They are machined to laminated sheets, laminated tubes, laminated bars and other profiles, and are mainly used in all kinds of electrical equipment, motors, HF equipment, aerospace equipment and others for parts insulation and installation purposes. Some laminated materials are also widely applied to the production of electronic devices. For example, they can be used as the fixture on the production line of PCBs of mobile phones, household apparatus and lighting.

Similarly, our composites are manufactured from resins and reinforced materials through hot pressing and curing processes. However, fiber glass mat formed from chopped fiber instead of a whole piece of fiber cloth is used to make the composite materials, ensuring that the materials have better formability and can be molded to various shapes.

FRIEND Group, as a pioneer in providing insulation materials and composite materials, offering products like electrical insulation materials, GPO3 laminate sheet, SMC sheet molding compounds, composite damping material, as well as engineered plastic machined components. The laminate products can be made with materials as cotton fabric reinforced phenolic, paper reinforced phenolic, glass reinforced polyester, glass fiber reinforced epoxy, etc. As one of China Aerospace Business Partners, our insulation and composite materials have been used in China spacecraft like Shenzhou and Chang'e. Choose us as we always focus on product quality.
