PA6 high thermal stability of long-term supply, can not hang up in the tin soldering 270 degrees; application of folding PA6 in daily necessities in the Asia Pacific International polyamide glass fiber reinforced material has good dimensional stability and low warpage, solderability and paint, easy spraying, ultrasonic welding materials, too good gloss, can be dyed various bright colors, in order to meet the requirements for use in industrial products, enhanced polyamide material should meet the following requirements: 1). The strength and durability, rigidity and heat resistance combined with excellent 2). Optimization design components, coloring excellent surface appearance, perfect, can be applied to the structure forming complex, and help developers to develop new product modeling design 3). Good processability, fluidity and excellent thermal stability of the material processing more relaxed conditions, make note Miniaturization of plastic parts PE disadvantages: (1) resistance to ageing (thermal oxidative aging) is poor - antioxidants and UV absorbers; (2) under the action of force, the thermal deformation temperature is very low. Linear low density polyethylene (LLDPE) The production process of linear low density polyethylene by solution method and gas chromatography, ethylene with alkyl branched olefins, such as 4- (4-methyl-1-pentene) - methyl cyclopentene, cyclohexene, 1-octene copolymer can be obtained as linear low density polyethylene (LLDPE). Can also be characteristic of other monomers LLDPE? Linear low density polyethylene, there are only short chain molecules; mechanical performance between high and low density polyethylene both; melting point than ordinary low density polyethylene high temperature of 15 DEG C; low temperature resistant performance than low density polyethylene; environmental stress cracking resistance ratio the high number of ordinary low density polyethylene ten times. Low density polyethylene (LDPE) Process for the production of low density polyethylene (LDPE), using oxygen?or?peroxide as initiators to polymerize ethylene into low density polyethylene. PP KD-822: it is suitable for small area (9 square centimeters) PP polypropylene adhesive and PP transparent sheet folding box, transparent viscous liquid colloid; up to PP plastic pick break not degumming result but not resistant to 80 degrees above water for 2 G-922: suitable for large-area PP polypropylene adhesive, transparent viscous colloid liquid, need double brush glue, hanging after jointing, water resistance, oil resistance, but not resistant to high temperature above 80 degrees G-1805H 3: suitable for large-area PP polypropylene adhesive colloid, yellow viscous liquid, high bonding strength, water resistance, oil resistance, but not resistant to high temperature above 80 degrees. PPO material properties 1, white particles. Good comprehensive performance, can be used in 120 degrees steam, good electrical insulation, water absorption is small, but there is stress cracking tendency. The modified polyphenylene oxide can eliminate stress cracking. It has outstanding electrical insulation and water resistance, good dimensional stability. The dielectric properties of the first in the plastic, MPPO as modified materials of PPO and HIPS prepared, currently on the market of materials are the materials, with ABS, HDPE, PPS, PA, HIPS, glass fiber and other blended modification.
