Phenolic Moulding Compound with Glass fiber filled in High performance for Grinding Wheels
Product description
Phenolic moulding compound(PMC) 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.
Used under the upper temperature limit of 250℃ and the upper voltage limit of 220V
Suitable for handles and knob of electric oven and top grade pan, coil holders
☆ Improved Impact Strength
☆ Rapid Curing
☆ Excellent Heat Resistance
