Introduction
For the five largest engineering plastics in the largest yield, the largest variety, the most versatile varieties. Nylon in the main varieties are nylon 6 and nylon 66, the absolute dominant position, nylon 6 is polycaprolactam, and nylon 66 is polyhexamethylene adipate Nylon 6 , nylon 9, nylon 9, nylon 13, nylon 6, nylon 6, nylon 6, nylon 6, nylon 6, nylon 6, nylon 6, nylon 6, Nylon 9T and special nylon MXD6 (barrier resin), nylon modified varieties such as nylon, single-cast nylon (MC nylon), reactive injection molding (RIM) nylon, aromatic nylon, transparent nylon, high Anti-tough nylon, nylon, nylon, nylon and other polymer blends and alloys, to meet the different special requirements, widely used as metal, wood and other traditional materials substitutes.
Modified nylon is a kind of engineering plastics , is based on nylon raw materials as the base material to change its physical properties and the formation of granular products.The output of such products is based on the needs of some manufacturers and the need for modified production of.
Modified nylon generally includes:
characteristic
1. Thermal properties: glass transition temperature (T g) and melting point (T m); high heat distortion temperature (HDT); long-term use of high temperature (UL- 746B); use temperature range; small thermal expansion coefficient.
2. Mechanical properties: high strength, high mechanical modulus, low latency, strong wear resistance and fatigue resistance.
3. Other: chemical resistance, electrical resistance, flame resistance, weather resistance, good dimensional stability.
The output of these products is based on the needs of some manufacturers and the need for modified production, modified nylon generally include: enhanced nylon, toughened nylon, wear-resistant nylon, halogen-free flame retardant nylon, conductive nylon, flame retardant nylon and many more.
Modified nylon has a lot of features, therefore, in the automotive, electrical equipment, mechanical structure :, transport equipment, textiles, paper machinery and other aspects of widely used.
classification
Modified nylon is divided into: 1, enhanced nylon 2, flame retardant nylon 3, transparent nylon 4, wear nylon 5, toughened nylon

Car: cooling fan, door handle, fuel tank cover, intake grille, water tank cover, lampholders
Industrial parts: chair seat, bicycle box, skate base, textile shuttle, pedal, pulley
Process conditions
Drying: If the material is sealed before processing, then it is not necessary to dry. However, if the storage container is opened, it is recommended to dry in hot air at 85 ° C. If the humidity is greater than 0.2%, it is necessary to carry out 105 ℃, 12 Hour of vacuum drying.
Melting temperature: 260 to 290 C. The glass additive product is 275 to 280 C. The melting temperature should be avoided above 300 C. Mold temperature: 80 ° C recommended. Mold temperature will affect the crystallinity, and crystallinity will affect the product's physical For thin-walled plastic parts, if the temperature of the mold below 40 ° C is used, the crystallinity of the part will change with time. In order to maintain the geometrical stability of the plastic parts, annealing is required. 750 ~ 1250bar, depending on material and product design Injection speed: high speed (slightly lower for reinforced material). Flow and gate: Due to the short settling time of PA66, the location of the gate is very important. The diameter should not be less than 0.5t (where t is the thickness of the plastic part.) If the hot runner is used, the gate size should be smaller than using a conventional flow path because the hot runner can help prevent premature solidification of the material. The minimum diameter of the mouth should be 0.75mm. Typical Use PA66 is more widely used in the automotive industry, instrument housings and other products that require impact and high strength requirements. Transparent or opaque milky white crystalline polymer with Plastic. Density 1.15g / cm3. Melting point 252 ℃. Brittle temperature -30 ℃. Thermal decomposition temperature is greater than 350 ℃. Continuous heat 80-120 ℃, balanced water absorption of 2.5%. Acid, alkali, most Inorganic salt aqueous solution, haloalkane, hydrocarbon, ester, ketone and the like.
