        1. Zytel®/Minlon® nylon resin

         nylon DuPont company Wallace Hume Carothers于1934-1935发明, 并于1938 year 投入商业化 application.

         advantages: strong/high degree large; resistant impact; resistant scratch; and resistant multiple chemical solvent agent;且 tool lubricated property; melting point high (约215～225℃); molding easy hot understanding ······

         disadvantages: easy water; lightfast property 差;不 resistant acid alkali.

         modified direction: heat stabilized; formed promote; light stabilization; resistant hydrolysis; toughened; flame retardant; increase lubricated property; increase rigid property (glass fiber (GF), material, Kevlar fiber)······

         DuPont as is nylon industry 领头羊, its many product has property can and features, 如:

        GRZ—— tool has rigid property and strong/high degree;

        Minlon®—— rigid property and tough property 完美结 combined, tool has good dimensional stability;

        High Productivity—— can fast speed molding, flow property good;

        Zytel®PA612——突出 dimensional stability and chemical resistance;

        Zytel®ST——卓越 tough property;

        Zytel®HTN—— excellent heat resistant property, water property small;

        ······

        2. Delrin® polyoxymethylene (POM) resin

        Delrin®acetal由 DuPont in 50 year 代末期发明. polyoxymethylene (POM) separation POM copolymer and POM homopolymer types. DuPont polyoxymethylene (POM) is POM homopolymer.

         advantages: 无 must reinforcement, tool has high rigidity; in temperature degree scope/range inner tool has high toughness; use temperature degree scope/range 广; resistant fatigue property can good; resistant creep property good; dimensional stability good, water absorption low; chemical resistance and resistant property good; friction coefficient small; has FDA can; can provide resistant UV and other grade; tool has good color property; low abrasion consumption ······

         disadvantages: most large long use temperature degree <90℃; most large short heat resistant temperature degree <120℃;无 flame retardant rating; resistant hydrolysis property good (hot water);缺口敏感 property 差; can resistant strong/high acid and strong/high alkali.

         modified direction: filling; toughened; wear resistant;······
