WebAbstract The heat resistance of the multiphase friction materials made with straight phenolic resin (ST), boron-phosphorous (B-P)-modified phenolic resin (BP), or polyimide (PI) was investigated using a Krauss-type friction tester. WebNovolac resins are amorphous (not crystalline) thermoplastics. As they are most typically used, they are solid at room temperature and will soften and flow between 150° and 220°F (65°C - 105°C). The number average molecular weight (Mn) of a standard phenol novolac resin is between 250 and 900.
