PP-LGF

Glass fiber reinforced PP, usually, the tensile strength of PP material is between 20M~30MPa, bending strength is between 25M~50MPa, bending modulus is between 800M~1500MPa. If PP is to be used in engineering structural parts, it must be reinforced with glass fiber.

Glass fiber reinforced PP, through glass fiber reinforced PP product mechanical properties can be multiplied or even several times the improvement. Specifically, the tensile strength reaches 65MPa~90MPa, the bending strength reaches 70MPa~120MPa, and the bending modulus reaches 3000MPa~4500MPa. Such mechanical strength can be completely comparable with ABS and enhanced ABS products, and it is more heat resistant.

Glass fiber reinforced PP, general ABS and reinforced ABS heat resistance temperature between 80℃~98℃, and glass fiber reinforced PP material heat resistance temperature can reach 135℃~145℃.

PP filling modification, adding a certain amount of inorganic minerals in PP, such as talcum powder, calcium carbonate, titanium dioxide, mica, etc., can improve rigidity, improve heat resistance and luster; Filling carbon fiber, boron fiber, glass fiber can improve the tensile strength; Adding flame retardant can improve flame retardant property. Filling antistatic agent, colorant, dispersant, etc. can improve the antistatic property, colorability and fluidity, etc.; Filling nucleating agent can speed up the crystallization speed, increase the crystallization temperature, form more and smaller spherical crystals, thus improving the transparency and impact strength. Therefore, the filler has a significant effect on improving the performance of plastic products, improving the plastic molding processability and reducing the cost.

Application

As one of the four general plastic materials, PP has excellent comprehensive performance, good chemical stability, better molding performance and relatively low price; But it also has the strength, modulus, hardness is low, low temperature impact resistance strength is poor, forming shrinkage, easy aging and other shortcomings. Therefore, it must be modified so that it can adapt to the demand of the product. The modification of PP material is generally through adding mineral reinforcement toughening, weather resistance modification, glass fiber reinforcement, flame retardant modification and super toughness modification, and each kind of modified PP has a large number of applications in the field of household appliances.

Glass fiber reinforced PP, can be used to make refrigerators, air conditioning refrigeration machines such as axial flow fans and cross flow fans. In addition, it can also be used to manufacture the inner drum of high speed washing machine, wave wheel, belt wheel to adapt to its high requirements on mechanical properties, for the rice cooker base and handle, electronic microwave oven and other places with high requirements on temperature resistance.

Полипропилен, армированный стекловолокном. Обычный полипропилен, армированный коротким стекловолокном, поскольку стекловолокно содержит короткое, легко деформируемое, имеет низкую ударную вязкость, легко деформируется при нагревании, длинное стекловолокно может преодолеть вышеуказанные дефекты короткого стекловолокна, а продукт имеет лучшую поверхность, более высокую температуру, более высокая ударная вязкость, может использоваться в холодильниках и кухонной технике с повышенной термостойкостью.

Полипропилен, армированный стекловолокном, создан на основе исходного чистого полипропилена с добавлением стекловолокна и других добавок, чтобы расширить сферу применения материалов. Вообще говоря, большинство материалов, армированных стекловолокном, используются в конструкционных частях продукта, который является своего рода конструкционным инженерным материалом.
