High Strength Bakelite Moulding Powder High Copper Adhesive For Commutator
Bakelite Moulding Powder with High-copper adhesive for Commutator
Product Description
● Based on phenolic novolak resin,glass fiber and mineral dust filled
● UL94 V-0 Certifed,low water absorption
● designed for high strength and temperature resistance
Bakelite Moulding Powder(PMP) are produced with with heated rollers or extruders.Treatment of a mixture of phenolic novolac resin,hexamethylenetetramine, fillers and additives leads to an intermediate, the actual moulding material. The polycondensation is driven so far that the moulding material in the final molding step can still flow, but so that the final cross-linking occurs very quickly. Especially important processing properties are good flow characteristics and rapid curing.
