Phenolic molding compound can be used to make various plastic products. It has a wide range of applications. For example, many plastic parts on automobiles can be produced using phenolic molding compound. It has good insulation and is suitable for automotive use. Let us talk about its physical properties.

Physical properties:

1. Phenolic plastic is a hard and brittle thermosetting plastic, commonly known as bakelite powder, which has high mechanical strength, toughness and wear resistance, stable dimensions, corrosion resistance and good electrical insulation.

2. It has excellent thermal performance. Under the load of 1.86MPA, its thermal deformation temperature is as high as 175℃, and its decomposition temperature is 443℃. Its various strength and performance are less affected by temperature.

Molding performance:

1. As the wall thickness of the product increases, the molding shrinkage rate increases.

2. The hygroscopicity is small, about 0.1-0. 3%, but a small amount of water will cause the decomposition of polyaramid during injection molding, so the material must be dried before molding to make its moisture content less than 0.02%.
