Heat stable phenolic composition |
摘要 |
A phenolic compound having improved retention of useful properties over long periods of time at elevated temperatures is presented. The novel phenolic compound, preferably a glass reinforced phenol-formaldehyde with mineral fillers has incorporated therein elastomers which primarily undergo crosslinking on oxidative aging, such as butadiene based rubbers, and/or molecular sulfur or sulfur donor components. These additives unexpectedly retard thermal degradation with time of aging and provide exceptionally good retention of weight, molded dimensions and mechanical properties.
