Epoxy vinyl Resin called anti-corrosion industry leader in many other ways also have applications, including automobile manufacturing. According to China Epoxy Resin Industry association experts, Vinyl Ester Resin can make all kinds of vehicle components, such as car tyre has also successfully with high strength and vinyl ester resin suppress, than metal tire weight 40 ~ 50%, from 160 ~ 200 ℃ in electrical equipment can be run continuously for more than 10 years and keep enough mechanical strength and dimensional stability. Epoxy vinyl ester resin has higher elongation have better shear strength, the impact of the higher than ISO polyester and good creep resistance and fatigue resistance, and good molding liquidity in the SMC parts making cars, the obtained compelling applications. Expert says, these components include wheel, seat, heat dissipation frame, gate board, engine valve sleeve, etc.
According to the China epoxy resin industry association experts introduced: sheet metal material on the total cost advantage integration is difficult, but many parts total amount is large, is the second placing signage at the noise, corrosion resistance is low; The appearance of the cast aluminum products quality is better than other non-ferrous metals, but the cost is higher, sound-absorbing, poor corrosion resistance; Thermoplastic composite materials (mainly glass fiber reinforced nylon) of superior machinability, short production cycle, but high temperature aging problems, poor durability, size is not stable and cause poor sealing.
So analysis think SMC and BMC is one of the ideal material for the valve set. Cytec Industries Inc Cyglas 695 BMC engine parts production, is a kind of vinyl ester resin containing 25% glass fiber BMC products, including the molding Cornette 5.7 L car cylinder valve cover, injection moulded a 4.3 L 12 gm truck before timing gear chain cover, injection moulded a 5.7 L 3 gm truck before timing gear chain cover, 2.7 L V6DOHC cylinder valve cover, etc.
Vinyl ester resin BMC cylinder valve cover, working temperature of 138 ~ 149 ℃, the curing speed (45 s curing products 3 mm thick, 1.4 ~ 1.8 kg of the valve cover, 1 min curing), good dimensional stability, good resistance to chemical corrosion. China epoxy resin industry association experts say the future, this kind of material to a wide range of applications in the field of transportation, mainly lies in the spare parts, including wheel, seat, heat dissipation frame, gate board, engine valve sleeve, etc
