摘要
Thermosetting plastics material consist of a dry refined phenoloc novalac reinforced by a fibrous polyamide, and having a specific weight of 1.2 - 1.22 g/cm3, a specific resilience of 10 - 120 kg/cm cm2, a Raschig fluidity of 40 - 120 mm, a speed of hardening at 140 - 150 degrees C of 0.5 - 1.5 mn-mm, and a Martens thermal stability of 120 - 130 degrees C. Useful for making weaving shuttles and other articles needing good sound deadening and antifriction properties.
