Xiamen LFT-G Polyamide 66 long glass fiber reinforced thermoplastic compounds high strength

What is PA66?

PA66, abbreviation of Polyamide 66, chemical name polyadiptyl adiptyl diamine, commonly known as nylon 66. Is a colorless transparent semi-crystalline thermoplastic polymer, widely used in automobiles, electronic appliances, mechanical instruments, industrial parts and other industries.

What is PA66-LGF?

However, due to the large absorbency of nylon itself, poor acid resistance, low impact strength of dry state and low temperature, and easy deformation after water absorption, the dimensional stability of the product is affected, so that its application range is limited to some extent. In order to improve the above shortcomings, expand its application field, and better meet the requirements of performance, people adopt a variety of methods to modify PA66 plastic, so as to improve the impact property, thermal deformation property, forming processing property and chemical corrosion resistance.

Because the specific strength and Young's modulus of glass fiber (LGF) are 10~20 times larger than that of PA66, the linear expansion coefficient is about 1/20 of that of PA66, the water absorption is close to zero, and it has good heat and chemical resistance, glass fiber filling is the most commonly used enhancement modification method of PA66.

PA66 is the variety with the highest mechanical strength and the most widely used in PA series. Because of its high crystallinity, it has high rigidity and heat resistance.

TDS of Polyamide 66 filling LGF

Translucent or opaque opalescent crystalline polymer with plasticity. It has excellent wear resistance, self lubricity and high mechanical strength.

Application

1. The automobile industry
Because of its excellent heat resistance, chemical resistance, strength and convenient processing, nylon 66 has been widely used in the automobile industry. At present, it can be used in almost all parts of the automobile, such as the engine parts, electrical parts and body parts. The engine part includes the intake system and the fuel system, such as the engine cylinder head cover, throttle, air filter machine housing, vehicle air horn, vehicle air conditioning hose, cooling fan and its housing, water inlet pipe, brake oil tank and cover, and so on. Body parts include: car fender, rear view mirror frame, bumper, dashboard, luggage rack, door handle, wiper bracket, seat belt buckle, interior decoration and so on. Car electric appliances such as electric control doors and Windows, connectors, crisper, cable tie wire.

2. Electronic and Electrical industries
PA66 can produce electronic and electrical insulation parts, precision electronic instrument parts, electrical lighting appliances and electronic and electrical parts, can be used to make rice cookers, electric vacuum cleaners, high-frequency electronic food heaters, etc. PA66 has excellent solder resistance and is widely used in the production of junction boxes, switches and resistors. Flame retardant grade PA66 can be used for color TV wire clip, fixing clip and focusing knob.

3. Machinery transportation and machinery and equipment industry
PA66 can be used for door handles of passenger cars and brake joint discs of freight cars. Other products such as insulation washer, baffle seat, turbine, propeller shaft, screw propeller and sliding bearing on ship can also be made with PA66. High impact resistance nylon 66 can also be made pipe pliers, plastic molds, radio control body, etc. Unreinforced grade nylon 66 is usually used to manufacture nuts, bolts, screws, nozzles, etc. with low creep and no corrosion. Reinforced grade nylon 66 used in the production of chains, conveyor belts, fan blades, impeller and scaffolding fixed foot buckle.

Frequently asked questions

1. How to choose the fiber content of the product? Is the larger product suitable for higher fiber content material?

A. This is not absolute. The content of glass fiber is not more is better. The suitable content is just to meet the requirements of each products.

2. Can products with appearance requirements be made of long-fiber materials?

A. The main feature of LFT-G thermoplastic long glass fiber and long carbon fiber is to show the mechanical properties. If the customer has bright or other requirements for the appearance of the product, it needs to be evaluated in combination with specific products.

3. How to choose the reinforcement method and length of the material when using long fiber reinforced thermoplastic material?

A. The selection of materials depend on the requirements of the products. It is necessary to assess how much the content is enhanced and how much length is more appropriate, which are depending on the performance requirements of the products.
