More Information
Summary:High temperature phenolic resins suited for use for example in an automotive or similar brake or in a clutch, are provided by a blend of the reaction product of a phenolic compound, naphthalenic compound, and formaldehyde with selected prior art resins. The mole ratio range of naphthalenic compound: phenolic compound: formaldehyde is about 1: 0.8-5: 1-10. Friction particles and friction elements can be prepared from said reaction product optionally being blended with said selected prior art resins. An improved method of making friction elements is also provided which uses such binder.
