1, different characteristics
PA is also known as polyamide, non-toxic and safe, does not contain bisphenol A, fully transparent, tough, abrasion-resistant, oil-resistant, water-resistant, enzyme-resistant bacteria, PA has a good combination of properties, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and a low coefficient of friction, with a certain degree of flame retardancy.
PPSU chemical name is polyphenylsulfone, the appearance of the color is a light golden yellow, but also has excellent resistance to drugs and acid-base resistance.
2, different temperature resistance
PA material melting point of 220 ℃ or more, can be sterilized below 200 ℃.
PPSU material is resistant to high temperatures up to 180 degrees, can be repeatedly sterilized.
3, the application of different
PA wide range of uses, is a plastic instead of steel, iron, copper and other metals, a good material, is an important engineering plastics; cast nylon widely used instead of mechanical equipment wear parts, instead of copper and alloys for the wear parts of the equipment. Coil tube frame, contactors; in household appliances for microwave oven equipment, hair dryers, dietary tableware, cups, bottles and so on.
