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.
