Introduction

PA66 for the five major 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 poly Diamine, nylon 66 , nylon 6 , nylon 9 , nylon 9 , nylon 13 , nylon 6 , nylon 6 , nylon 6 , , Nylon 9T and special nylon MXD6 (barrier resin), nylon modified varieties such as enhanced nylon, single-cast nylon ( MC nylon), reactive injection molding (RIM) nylon, aromatic nylon, transparent nylon, High impact (super tough) nylon, electroplated nylon, conductive nylon, flame retardant 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:

Reinforced nylon, toughened nylon, wear-resistant nylon, halogen-free flame retardant nylon, conductive nylon, flame retardant nylon and so on.

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

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, the instrument shell and other products that require impact and high strength requirements. Transparent or opaque milky white crystalline polymer, Has a plasticity . 15g / cm3 . Melting point 252 ℃ . Brittle temperature -30 ℃ . Thermal decomposition temperature is greater than 350 ℃ . Continuous heat 80-120 ℃, balance water absorption 2 . 5% . Can acid, alkali, most inorganic salts of water, halogenated alkanes, hydrocarbons, esters, ketones and other corrosion .

PA6 automotive applications and requirements

Automotive applications

PA6 has a wide range of applications in automobiles. The automotive is an important and fast growing market for plastics. PA6 has a good overall performance, low density, easy molding, freedom of design, insulation, and a significant advantage in mold and assembly costs .PA6 not only high tensile strength, excellent impact performance and high heat distortion temperature, heat resistance, low coefficient of friction, wear resistance, self-lubricating, oil resistance, excellent chemical resistance, and especially suitable for filling with glass or other materials Enhance the performance of the material and grade to meet the final parts and customer needs.At present PA6 a wide range of automotive products, such as radiator box, front grille, heater box, radiator blades, steering column cover, tail lamp cover, adsorption tank Air conditioning, air intake, air intake, air conditioning, air conditioning, air conditioning, air conditioning, air conditioning, air conditioning, air conditioning, Pump impeller, bearings, bushings, seat, door handle, wheel cover, etc., in short, involving the car engine parts, electrical components, body parts and airbags and other parts. Under the hood under the largest amount of spare parts, which is due to the miniaturization of the car, lightweight development, the engine room volume reduction, the temperature increases, requiring lower parts under the hood more high temperature, and PA6 through modification, can fully meet the above requirements. Industrial analysts believe that PA6 components not only play a protective role, but also aesthetically pleasing.

In order to meet the requirements of the use of the peripheral components of the engine, polyamide materials should have the following advantages: In order to meet the requirements of the use of the peripheral components of the engine, the polyamide material should have the following advantages:
1). Excellent strength and toughness to meet the mechanical properties of structural parts;
2). Excellent heat resistance, can be used at temperatures up to 130 ℃;
3). Long-term fatigue resistance, good performance after heat aging;
4). Excellent dimensional stability, with anti-warping effect;
5). The surface effect is good, no floating fiber;
