Modified Phenolic Resins for High Performance Friction Applications 2001-01-3127

Phenolic resins have been widely used as binders for Friction Materials. Increased performance requirements have driven the improvement of phenolic resins. Phenolic resins modified with silicone gel, NBR, and aromatic compounds were presented at the 18th ANNUAL BRAKE COLLOQUIUM & EXHIBITION in 2000, their performance levels and capabilities were described.
As market demands increase, enhanced phenolic resins as binders are needed to provide high performance friction products with superior heat resistance and noise properties.
This presentation will review the following resins:
PR-ANP-50LB (a high resistant resin) its heat resistance has been greatly improved compared with the resin presented last year.
PR-54365 (acrylic rubber modified resin) providing excellent flexibility and vibration absorption.
PR-EPN (gas free resin) is able to reduce frequency of gas venting during molding frictions, thus shortening the molding time.
These resins will be presented along with detailed performance data including wear, friction coefficients, Rockwell hardness, flexural modulus, dynamic viscoelasticity and vibration absorption.
