EEA resin is in 专门改装 high pressure polyethylene (PE) reaction device in free radical polymerization method production. acrylic ester (EA) content increase 时, copolymer will more tough, more soft/flexible, more has elastic property. high acrylic ester content resin property, increase surface absorption ink can force tool has bonding property 质.
EA content increase, copolymer density and soft/flexible increase. EEA poly has good low temperature property can and soft/flexible property, processing in heat stabilized property good, has relatively large filler property, excellent resistant bending cracking and ring force cracking property, tool has relatively large elastic property and other. EEA and has machine oxidation material crosslinked can improve/increase heat resistant property, creep resistance, resistant solvent agent property.
当 acrylic ester (EA) content rise high 时, copolymer upper use temperature degree has decline, transparent degree reduce.
features:
1, EEA copolymer can and has polymer versus solvent, 如:VLDPE, LDPE, LLDPE, HDPE and polypropylene (PP) and other;
2, for force fracture, impact, and bending fatigue has relatively strong/high resistant force;
3, relatively good low temperature property can and more low melting point.
advantages:
1, cost low
2, transparent can color
3, dimensions features
4, high rigidity
application areas:
1, EEA used as easy 弯, resistant 折, elastic property good soft tube/pipe, low temperature degree 密封圈, cable semi property sleeve/set tube/pipe, use bag, outer sleeve/set, packaging film and container and other.
2, EEA can used for high temperature resistance extrusion coating (for 基体材 material adhesion force good) and other plastics low temperature resistant and resistant ring force cracking modifier.
3, EEA can 参入炭黑 made conductive property material.
4, EEA can injection molding automotive 驾驶盘 and its it parts, electrical machine parts, safety device tool, cold shallow 盘, use product, shoe sole and other.
5, EEA can in molding various type and product container.
6, EEA can coating products and lamination products can as various packaging materials, metal coating.
7, EEA can used as electrical insulation material, shrinkage packaging film, shrinkage pipe/tube, composite/compounding film and foam plastics and other.
EEA versus for/regarding EVA, POE, EAA and other various polyolefin resin, in food packaging application comparison more, but also EA content can ultra- FDA 规定 8%.
