| Trademark: | Friend |
Beijing New Friend Insulation Material Co., Ltd. is the leading manufacturer of high performance thermoset composite materials. We work directly with customers to manufacture the highest quality specialty sheet products, pre-pregs, rods and molded shapes, and tubes to meet demanding composite applications for our OEMs and fabricators around the world.
Beijing New Friend Insulation Material Co., Ltd. Offers a variety of paper phenolic sheets. This cost-effective line of products consists of multiple plies of various papers impregnated with phenolic resins and laminated under heat and pressure to produce a thermoset composite. Both papers and resins can be modified to change the finished properties of the final laminate. These products offer thermal, mechanical isolation, and thermal and electrical insulation properties that meet or exceed those of most thermoplastic materials. The properties and cost-effectiveness of these products often make them the insulators of choice in low-voltage, dry-service electrical equipment.
Characteristics of Phenolic Paper Laminated Sheet:
The Phenolic paper laminated sheet is a kind of insulation sheet made from phenolic resin and cellulose paper and has good electrical performance under normal condition. The products can be made into insulating parts of electric machinery and electrical equipment that requires high electrical and mechanical performance. It can be used in transformer oil.
