High heat-resistant powder resol resin, an insulating material that enhances the safety of electrical products.
Case studies of powder resol for electrical insulation materials: It is heat and chemical resistant, and once cured, it does not deform, making it suitable for precision insulation boards and molded products.
Powdered resol resin (pure resol) is a powdered form of resol-type phenolic resin with an extremely low amount of monomers. It not only suppresses odor generation but also complies with regulations (not classified as a toxic substance under the Poisonous and Deleterious Substances Control Law). We offer a range of grades that provide various benefits, such as improved workability and mixability, tailored to specific applications and requirements. This time, we would like to introduce a case study utilizing powdered resol resin as an electrical insulation material. [Case Study] Target: Insulation boards, precision molded parts Role: A raw material mixed with fillers to form non-conductive (insulating) parts Reason: It possesses heat resistance after curing, mechanical strength, and excellent electrical insulation performance Effect: Extends the lifespan of parts, prevents short circuit accidents, and provides high dimensional stability *For more details, please download the PDF or contact us.
