Softening temperature, molding temperature, etc. The thermal-temperature effects of acetate fiber skeleton are as follows: softening temperature is 60~75 degrees, molding temperature is 80 degrees; Not easy to burn. Poor contractibility. This material becomes brittle after repeated heating. The thermal-temperature effect of epoxy lens frame is that the softening temperature is 80 degrees and the molding temperature is 100~ 120 degrees. When cooled sharply, the material technology becomes brittle.
