Encyclopedia of Science and Technology Co., Ltd. Shenzhen Jin Yang: 15013855069 www.51chinaall.com A-665 of the materials? A-665 is mainly used for particle toughening PA PA special plastic material description: polyamide 6 or nylon 6 (PA6) formula: [- NH- (CH2) 5-CO] n- Properties: translucent or opaque white crystalline polymers Features: thermoplastic, lightweight, good toughness, chemical resistance and durability Burning Identification: blue yellow flame, burning taste of plants Solvent experiments: anti-cyclohexanone and aromatic solvents Density: 1.13g / cm3 Melting point: 215 ℃ thermal decomposition temperature:> 300 ℃ Equilibrium water absorption: 3.5% with good wear resistance, self-lubrication and solvent resistance. Density: (g / cm3) 1.14-1.15 Melting point: 215-225 ℃ Tensile strength:> 60.0Mpa elongation:> 30% Bending strength: 90.0Mpa notched impact strength: (KJ / m2)> PA characteristic of PA and use: Features: excellent wear resistance and self-lubricating, high heat resistance and mechanical strength, excellent low temperature performance, self-extinguishing, oil, chemical resistance, good elasticity, high impact strength, alkali resistance resistance, UV and sunlight purposes: connectors, reel, timer, cover circuit breakers, switches shell seat cooling fans, door handles, fuel tank cover, grille, radiator cover, lamp seat, bicycle transportation box , skates base, textile shuttle, pedal, slip lose PA materials: crystalline thermoplastic plastic, a clear melting point, Nylon6 Tm of 220 ~ 230 ℃, Nylon66 was 260 ~ 270 ℃, Nylon with a water-based and therefore absorption sex, be dried before molding, high temperature drying the nylon grain discoloration PA molding: 1, crystalline materials, high melting point, narrow melting temperature range, poor thermal stability, the material temperature over 300 degrees, the residence time of over 30 minutes decomposition . Easier absorbent, to be dried, the moisture content should not exceed 0.3%. 2, good mobility, easy flash. Self-locking nozzle is appropriate and should be heated. 3, mold shrinkage and shrinkage range, clear direction, prone to shrinkage and deformation. 4, mold temperature by plastic wall thickness in the range of 20 to 90 degrees selection, injection pressure by injection machine type, material temperature, shape and size of plastic parts, die casting system is selected, the molding cycle is selected according to the thickness of plastic parts. Resin viscosity hour, injection, cooling should take a long time, and with white oil as a release agent. 5, in the form and dimensions of the die casting system, increasing the flow channel and gate size can be reduced shrink. Deficiencies of polyamides comprising: dimensional accuracy due to thermal expansion and water absorption actions insufficient, poor acid resistance, hardness and elastic modulus enough. After subsequent improvement, but also one of the more outstanding engineering plastics. PA shortcomings nylon high moisture absorption, dimensional accuracy and physical properties of the long-term affected. Add the amount of A-665 is the number? Addition: plastic materials or regenerated compound added 3% -6% of A-665 particle toughening, significant advantages can be achieved the effect A-665 is? Does not affect the plastic color, will not affect the performance of plastics in other areas. Simple: Just when mixing the toughening join and outlet materials, renewable raw materials and mixing for 5-8 minutes, then mix well after heating roasted material extrusion, injection molding or blow molding. A-667 dosage and usage: 1, the cost is very low: the amount of 3-6%, which was added 20-40 grams 1KG toughening material, very little amount; please use plastic sample with a mixer and stir 5- 8 minutes. 2, are easy to use: just when mixing the toughening join and outlet materials, renewable raw materials and mixing for 5-8 minutes, then mix well after heating roasted material extrusion, injection molding or blow molding. 3, packaging, storage and shelf life: paper bags or cartons, net weight 25 KG / parts, must pay attention to sun, moisture, pollution prevention, the product shelf life of three years. Note: The test plastic particles toughening effect, in the extrusion, injection molding or blow molding after 24 hours, so the effect is more obvious; the same kind of material with a plastic material for comparison, test products as much as possible without using a plane Kong products. Note: If this product accidentally splashed into the eyes, rinse with plenty of water or to a nearby hospital Tel: 400-606-5568 (Toll Free) 0755-28996208 Fax: 0755-28994568 Young S: 15013855069 QQ: 2356172901 Address: Longgang District, Shenzhen, Guangdong Province, Dragon street level five JCC love the industrial zone 16 Alibaba: http: //daquanhuagong.cn.alibaba.com/ official website: www.51chinaall.com/
