Moulding Compound (PF) is also commonly known as "Bakelite". It
is favorably used for various used due to the excellent heat resistant
and dimentional stability.
- Engineering Plastic can be categorized
into two kinds of resin: Thermosetting resin and Thermoplastic
resin. Phenolic Moulding Compound is thermosetting resin.
There are two types of phenolic resin
- Novolac and Resol. Where Novolac is two stage compound. And Resol is
one stage compound.
specifications of Phenolic Molding Compound
- Novolac (Two Stage)
The above two stage
process generates three-dimensional reticulated structure and Ammonia
Gas (NH3) after injection or compression process.
- Example of Novolac (two stage) phenolic molding compound are
General Purpose and Heat Resistance grade from Chang
Chun, Taiwan and Sumidurez, Singapore.
- Resol (One Stage)
Resol (one stage)
generate three-dimensional reticulated structure and water vapor (H2O).
As a result, NO ammonia gas is generated.
- Example of Resol (One stage)
phenolic molding compound are Sumikon PM9820 and PM9630 from Sumidurez,
material provided by Dowell Trading Co. Ltd.'s suppliers
are manufactured by two major manufacturers - Chang Chun, Taiwan &
- Because of the excellent heat
resistant and dimentional stability, phenolic moulding compound is
still be one of the most competitive product at all time.
