I have an argument on another forum. I need Engineers...
- Bakelaque is a rigid laminate or tube made from phenolic resin on a substrate cotton fabric, paper or glass.
- Bakelite is made from phenolic resin and wood flour.
- Novotext is cotton fibre-reinforced phenolic, using randomly oriented fibres.
- Paxoiln and Richlite are made from phenolic resin and paper.
- Tufnol is made from phenolic resin and woven cotton or linen fabric.
Phenolic is a paper and resign compound pressed in to the desired shape and heated, Plastic is a pure chemical mixture.
A phenolic must have paper in it?
no to all of the above. in organic chemistry, phenols - sometimes called phenolics - are simply a chemical compound containing a benzene ring and a hydroxyl group.Or is a phenolic considired the alloy of plastics?
Plastic= a phenolic?It depends. They make a plastic that is free of BPA(bisphenol acitate)
A study was done on some plastic product a while back and allot of the plastic used was showing traces of BPA in it when heated in the microwave. I used to make BPA and our unit was a 100 % phenol unit. We made it from a liquid form phenol/BPA into a solid.
the person who wrote that probably knows their bearings and retainers, but they don't know their chemistry. that's all. i think he just misused the word "phenolic." no biggie.Heres the post I was responded to. I called BS.
Those are the bearings you really want to use. The plastic retainers are far superior to the riveted or bent tab metal type.They wear better, have less corrosion issues, less drag and can take higher speeds. They are steadily replacing the phenolic cage type that were the king of high speed bearings.
