FR-4 epoxy plate processing red fr4 water green fr4 glass fiber plate processing engraving
application characteristics: 1, various forms: a variety of resins, curing agents, modifier systems can almost adapt to a variety of applications on the form of requirements, the range can be very low viscosity to high melting point solids.
2, easy curing: the selection of a variety of different curing agents, epoxy resin system can almost be cured in the temperature range of 0 to 180 degrees C.
3, strong adhesion: the presence of polar hydroxyl and ether bonds inherent in the molecular chain of epoxy resins, making it highly adhesive to various substances
China
. Epoxy resins are lowly constricted when cured, resulting in low internal stress, which also helps to increase the adhesion strength.
4, low shrinkage: Epoxy resin and the curing agent used are reacted by direct addition reaction or open-loop polymerization of epoxy in resin molecules, no water or other volatile by-products released. They show very low shrinkage (less than 2%) during curing compared to unsaturated polyester resins and phenolic resins.
5, aesthetic performance: cured epoxy resin system has excellent regenerological properties.
6, electrode performance: cured epoxy resin system is a high dielectural performance, resistance to surface leakage, resistance to arc of excellent insulation materials.
7, chemical stability: Usually, cured epoxy resin system has excellent alkaline resistance, acid resistance and solvent resistance. Like other properties of cured epoxy systems, chemical stability depends on the resin and curing agent chosen. Proper selection of epoxy resins and curing agents can make it have special chemical stability.
8, dimensional stability: the above-mentioned combination of many properties, so that epoxy resin system has outstanding dimensional stability and durability.
9, mold resistance: cured epoxy resin system resistant to most mold, can be used in harsh tropical conditions.
