PA
Poly Omid – have relatively low specific weight, impact and wear resistance, relatively good electrical insulation and resistance to solvents, oils, greases.
PA - polyamide
Polyamide, commonly known as nylon, is a technology polymer. It has relatively low specific weight, resistance to impact and wear, relatively good electrical insulation and resistance to solvents, oils, greases and self-extinguishing fuels. Unlike Acetal resin, this material is more stable at temperatures up to 140°C. It is used for bearing rings and bushings, where the temperature is constantly high. It is usually filled with glass fibers, but other additives such as carbon, PTFE, molybdenum disulfide can be used to achieve the desired physical and mechanical performance.

data sheet
POLYAMIDE (abbreviated PA) is known by the brand name Nylon. This polymer has very good strength, hardness, and wear resistance. The thermal tolerance of polyamide is between -40 and 100 degrees Celsius.
Polyamides are polymers that contain repeating amide bonds, -CO-NH-. Proteins are examples of naturally occurring polyamides. Nylons are crystalline polymers usually produced by the condensation of diamine and diamine. There are several types of nylon, and each type is often described by a number, such as nylon 66 (PA 66). Numerical suffixes refer to the number of carbon atoms in the amine and acid molecular structures, respectively. The acid group -COOH reacts with the amine group -NH2 to form amide.
