Phenolic molding plastics are
also known as electric wood powder or adhesive wood powder. It has good
electrical insulation performance and high temperature resistance, and is
used in the manufacturing of electronic appliances, daily industrial
products, and automotive components. It is a phenolic plastic mainly filled
with wood powder, which is molded into products through injection molding,
compression molding, and transfer molding. Unlike common thermoplastic
plastics, phenolic molding plastics are thermosetting plastics.
Packaging: 25kg/bag
Storage method: Store in a
ventilated, dry, and cool indoor environment with an ambient temperature not
exceeding 35 ℃. The storage period is one year. If it exceeds the storage
period and passes the performance index inspection, it can continue to be
used.
