Phenolic molding plastics are also known as bakelite powder and bakelite powder. They have good electrical insulation properties and high temperature resistance, and are used in the manufacture of electronic appliances, daily industrial products and automotive parts. It is a phenolic plastic mainly made of wood powder as a filler. It is formed (injection molding, pressing, transfer molding) into products. Unlike common thermoplastics, phenolic molding plastics are thermosetting plastics.
Packing: 25kg/bag
Storage method: Store in a ventilated, dry, and cool room where the ambient temperature does not exceed 35 ° C. The storage period is one year. If the storage period exceeds the required performance index, it can continue to be used.
