Methods To Improve The Wear Resistance Of Nylon Plastics

Nylon, also known as polyamide (PA), is a polymer obtained by polycondensation of diamines and dibasic acids, or a lactam polymer obtained by direct polymerization of amino acids. Nylon plastics themselves have excellent wear resistance, strength, toughness, and tensile strength, and can withstand long-term friction without being easily damaged. However, in order to further improve its wear resistance, the following methods can be adopted:

Adding wear-resistant additives
PTFE: PTFE has the lowest friction coefficient among all wear-resistant additives. During the friction process, the PTFE molecules worn out will form a lubricating film on the surface of the parts, which has good lubricity and wear resistance. In high-load applications, PTFE is the best wear-resistant additive.

Molybdenum disulfide (Moly): It is a wear-resistant additive for nylon plastics. It can increase the crystallinity of nylon and make the nylon material produce a harder and more wear-resistant surface. At the same time, molybdenum disulfide has a high affinity for metals and can fill the pores on the metal surface, making the metal surface smoother. It is suitable for applications where nylon and metal rub against each other.

Graphite: Graphite molecules slide easily on very small friction forces. Its wear-resistant properties are particularly important in water environments. It can be used as a wear-resistant additive for many applications placed in water, such as water pump housings, impellers and seals.

PTFE micropowder has an extremely low friction coefficient, which means that during the friction process, PTFE molecules can form a lubricating film on the friction interface. This film can effectively reduce friction resistance and wear rate, thereby improving the wear resistance of nylon. This self-lubricating property makes PTFE micropowder an ideal choice for improving the wear resistance of nylon.
