Powdered resol resin (pure resol) possesses characteristics such as heat resistance, wear resistance, and dimensional stability!
Powdered resol resin (pure resol) is a powdered form of resol-type phenolic resin with an extremely low amount of monomers. In addition to suppressing odor generation, it offers various benefits such as compliance with regulations (not classified as a toxic substance), improved workability and mixability, and is available in different grades according to applications and requirements. This time, we will introduce a case where powdered resol resin was utilized in automotive brake pads (friction materials). 【Case Study】 Target: Brake pads (friction materials) Role: Used as a binder for brake pads Reason: Exhibits stable friction characteristics even at high temperatures; resistant to seizing and wear Effect: Stabilization of braking performance, reduction of noise, extension of pad lifespan *For more details, please download the PDF or contact us.
