Polyamide PA12 characteristics Typical Applications: water table and other business equipment, cable sets, mechanical cam, sliding mechanism and bearings DVD, CD, MD, VCR, camcorder, digital cameras, printers and video recorders and other silent gear. Injection molding conditions: Drying: humidity must be processed prior to 0.1%. If the material is exposed to the air stored, recommended to be dried in a 85C hot air for 4 to 5 hours. If the material is stored in a sealed container, then after three hours the temperature balance can be used directly. Melting temperature: 240 ~ 300C; for the general characteristics of the material must not exceed 310C, for flame-retardant properties of the material should not exceed 270C. Mold temperature: For unreinforced material is 30 ~ 40C, or for large-area thin-walled member is 80 ~ 90C, for enhanced material is 90 ~ 100C. Increase in temperature will increase the crystallinity of the material. Precisely control the temperature of the mold is very important to PA12. Injection pressure: maximum to 1000bar (recommended for guaranteeing pressure and high melting temperature). Injection speed: high speed (for a glass additive material better). Runners and gates: For non-additive materials, due to the low viscosity material, runner diameter should be about 30mm. Material requirements for enhanced crowd channel diameter of 5 ~ 8mm. Runner should shape all round. Sprue should be as short as possible. You can use various forms of the gate. Large plastic parts do not use the small gate, which is to avoid excessive pressure on the plastic parts or excessive shrinkage. Gate thickness equal to the best and the thickness of plastic parts. If you are using submarine gates, the minimum recommended diameter of 0.8mm. Hot runner mold is very effective, but requires very precise temperature control to prevent leakage or solidification of the material in the nozzle. If you use the hot runner, gate size should be smaller than some cold runner. Chemical and physical properties: PA12 from butadiene linear, semi-crystalline - crystalline thermoplastic material. Its characteristics and PA11 similar, but different crystal structures. PA12 is a good electrical insulator and as polyamides and other moisture will not affect insulation performance. It has good chemical stability, impact resistance machines. PA12 has many improved varieties in the plasticizing features and enhancements regard. PA6 and PA66, and compared these materials have a lower melting point and density, with a very high moisture regain. PA12 of strong oxidizing acids without resistance. PA12 viscosity depends on humidity, temperature and storage time. It's good liquidity. Shrinkage of between 0.5% to 2%, depending on the variety of materials, wall thickness and other process conditions. Polyamide elastomer 12 (nylon 12 elastomer) belonging thermoplastic elastomer (TPE) material. For block polymers, including PA12 segments and polyether segments (polyether block amide). Rich PA12 PA12 products with the main character, and the nature of the elastomer with increasing polyether content becomes more obvious: that is, the polymer becomes more flexible, with higher low-temperature impact strength. Because of its excellent performance in many applications of the polymer are indispensable Note: 25 kg / wrap set, volume discounts, payment and delivery within one day reach the Pearl River Delta, the country around 3-4 days arrival The Company adequate supply, variety and reasonable prices.
