Engineering plastics exhibit higher performance than standard materials, making them ideal for tough engineering applications. They have gradually replaced traditional engineering materials such as wood or metal in many applications because, not only do they equal or surpass them in their weight/strength ratio and other properties, but they are also much easier to manufacture, especially in complicated shapes.
Engineering plastics have superior performance in the areas of heat resistance, chemical resistance, impact resistance, fire retardancy and mechanical strength.
Engineering plastics are used in applications including:
Electrical and electronics.
Building and construction.
Consumer goods and appliances.
Industrial applications such as abrasion-resistant and corrosion-resistant liners.
