Phenolic Resin
Application of Phenolic Resin
1. Phenolic Resin is used as the core adhesive for automotive brake pads and clutch plates. Characteristics: High temperature resistance, stable friction coefficient at temperatures above 300 ℃. Low wear rate and extended brake pad life. The high-speed railway braking system adopts phenolic resin based composite materials to meet the high-speed braking requirements.
2. Phenolic resin is used in electrical wood products, such as electrical switches, sockets, and tableware handles. Characteristics: High insulation and arc resistance. Low cost, suitable for large-scale injection molding.
3. Phenolic resin is used for bonding refractory bricks and ceramic fibers (such as blast furnace lining). Characteristics: Forming a carbonized layer at high temperatures to protect the substrate (with a temperature resistance of up to 1000 ℃).
4. Phenolic resin is used as an anti-corrosion coating for chemical storage tanks and ship walls. Blend with epoxy resin to enhance flexibility and adhesion.
5. Phenolic resin is applied to the insulation layer of copper-clad laminates (CCL) on circuit board substrates, such as FR-2 type substrates. Characteristics: High dielectric strength, arc resistance. The cost is lower than that of epoxy resin substrate (FR-4).
6. Phenolic resin is used for semiconductor packaging and electronic component encapsulation. Characteristics: Resistant to moisture and heat aging, protecting components from environmental corrosion.
7. Phenolic resin is used for building exterior wall fireproof insulation layer and fireproof door core material. When the oxygen index is greater than 35, it will foam and carbonize when exposed to fire, blocking the spread of flames.
8. Phenolic resin is used as a rubber reinforcing agent. Add phenolic resin to tires and conveyor belts to enhance wear resistance and tear resistance. Mechanism: Crosslinking with rubber molecules to form a three-dimensional network structure.
9. Phenolic resin is used for light heat insulation phenolic foam (such as insulation layer of building cold storage). Features: Flame retardant grade B1, low smoke density, superior to polystyrene foam.
10. Phenolic resin is used for bonding plywood, particleboard, and fiberboard. Advantages: Strong water resistance (especially modified phenolic resin), suitable for outdoor furniture. Low formaldehyde emission (E0 environmental standard).
