1. Phenolic molding compounds undergo condensation reactions during the curing process, resulting in the release of water. Therefore, during the heating and curing process, pressure must be applied, which requires the use of compression molding or lamination molding methods.


2. During the molding process, the mold temperature has a significant impact on the flowability of phenolic resin molding materials. Generally, when the mold temperature exceeds, the flowability rapidly decreases. Its curing rate is slow and it releases a large amount of heat, so thick walled products often experience uneven curing and overheating due to the difficulty in releasing internal heat.


3. Phenolic molding plastics usually require drying treatment before molding, with a drying temperature of 90-12 (Tt) and a drying time of 60 seconds.
