Phenolic Resin
Description
Phenolic resin is a kind of synthetic plastics, colorless or brown transparent solid, is widely used for electrical equipment, also commonly known as bakelite heat-resistant flame resistance water resistance and good insulation, good resistance to acid, alkali resistance is poor, mechanical and electrical performance is good, easy to cut, divided into two categories, thermosetting plastics and thermoplastic synthetic with different components, different function of modified phenolic resin can be obtained, it has characteristics of different, such as alkali resistance wear resistance oil resistance corrosion resistance, etc.
This series is a thermoplastic phenolic resin with yellow or light yellow flakes or rods, characterized in as follows:
1. high intensity, small amount consuming to low the cost
2. Little gas forming, reduce the air hole defect on cast and increase the rate of finished product.
3. Good liquidity, easy coated, full filling without dead angle
4. Low free phenol and low environment pollution, better the working environment.
5. Quick curing, improve the core shooting rate and shorten the working time
Designed for manufacture of brake pads, brake linings and clutch facings in braking system.Narrow particle size distribution,
consistent, high bonding strength.
Instruction:
1. Binder (5-20%) :phenolic resin, rubber
2.Fiber (5-35%): inorganic fiber (glass, ceramic, steel, copper); organic fiber (Kevlar, carbon fiber etc.)
3.Abrasive (0-10%): Aluminum oxide, iron oxide, zirconium oxide.
4.Filler (20-60%): Friction particle, Barite, Calcium carbonate, tire fiber, petroleum coke.
5.Lubricant (0-5%): Graphite, Molybdenum sulfide, antimony sulfide.
