lft-g PA66 material reforzado fibra de vidrio larga 30% especificación Poliamida66 plástico modificado

¿Qué es PA66?

PA66, abreviatura de Poliamida 66, nombre químico poliadiptil adiptil diamina, comúnmente conocido como nylon 66. Es un polímero termoplástico semicristalino transparente e incoloro, ampliamente utilizado en automóviles, aparatos electrónicos, instrumentos mecánicos, piezas industriales y otras industrias.

¿Qué es PA66-LGF?

Sin embargo, debido a la gran absorbencia del propio nailon, la escasa resistencia a los ácidos, la baja resistencia al impacto del estado seco y la baja temperatura, y la fácil deformación después de la absorción de agua, la estabilidad dimensional del producto se ve afectada, por lo que su rango de aplicación se limita a algunos medida. Con el fin de mejorar las deficiencias anteriores, ampliar su campo de aplicación y cumplir mejor con los requisitos de rendimiento, las personas adoptan una variedad de métodos para modificar el plástico PA66, a fin de mejorar la propiedad de impacto, la propiedad de deformación térmica, la propiedad de procesamiento de formación y la corrosión química. resistencia.

Debido a que la resistencia específica y el módulo de Young de la fibra de vidrio (LGF) son 10~20 veces mayores que los de PA66, el coeficiente de expansión lineal es aproximadamente 1/20 del PA66, la absorción de agua es cercana a cero y tiene buena resistencia al calor y a los productos químicos, el relleno de fibra de vidrio es el método de modificación de mejora más utilizado de PA66.

PA66 es la variedad de mayor resistencia mecánica y la más utilizada en la serie PA. Debido a su alta cristalinidad, tiene una gran rigidez y resistencia al calor.

Solicitud

1. La industria del automóvil
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.
