brief introduction of dupont pa66: nylon, polyamide in chinese, polyamide in english, is a general name of thermoplastic resin containing repeated amide group-[ nhco ] in the main chain of molecule. the nomenclature depends on the number of carbon atoms in the monomer. it was invented by dupont chemist wallace carothers and his scientific research. the product application * * , almost covering every field, is five major engineering plastics widely used varieties. pa66(polyamide 66 or nylon 66) , compared to pa6, pa66 is used in the automotive industry, instrument cases and other products re impact resistance and high strength re process conditions drying treatment: if the material is sealed before processing, then there is no need to dry. however, if the storage container is opened, it is recommended that it be dried in hot air at 85 ° c. if the humidity is greater than 0.2% , 105 ° c, 12 hours of vacuum drying is re melting temperature: 260 ~ 290 °c. the product of glass additive is 275 ~ 280 ° c. the melting temperature should not be higher than 300 °c. die temperature: recommended 80 °c. mold temperature will affect the degree of crystallinity, and the degree of crystallinity will affect the physical characteristics of the product. for thin-walled plastic parts, the crystallinity of the part will change over time if a mold temperature below 40 ° c is used, and annealing is required to maintain the geometric stability of the part. applications * * * used in machinery, instrumentation, automotive parts, electrical and electronic, railway, home appliances, communications, textile machinery, sports and leisure products, fuel pipes, tanks and some precision engineering products. electrical and electronic e: connectors, spools, timers, cover breakers, switch housings motor vehicles: cooling fans, door handles, fuel tank covers, intake grilles, water tank covers, lampholders industrial parts: seats, bicycle frames, roller skate bases, textile shuttles, pedals, slide transport classification * * * pa, conductive pa, adding fiber fireproof pa, fireproof pa, anti-ultraviolet weather resistant pa, high temperature extrusion grade pa..
