The physical properties of the nylon plate is very good, mechanical toughness and strength and metal similar; fatigue properties of nylon and aluminum plate of the same cast. And chemical stability nylon plate: alcohol, weak base, copper, esters, hydrocarbons, grease, etc. have no effect on the nylon plate. The wear resistance of nylon plate: friction coefficient is generally 0.1 to 0.3, is babbitt 1/3, 1/4 Bakelite is a very good self-lubricating material. At the same time, the nylon plate having excellent cold and heat resistance: the resistance to its highest temperature limit 100 ° C, a minimum of -60 ° C, in which case a certain mechanical strength to maintain normal operation. Nylon plate mechanical properties also very good: and has high tensile properties, surface hardness, flexural strength and impact strength and high ductility. Small (mass per unit volume light) nylon board density: its density is between 1.05 to 1.15. Nylon tubing instead of copper can be very intuitive to see the flow of the liquid, it can be bent freely according to user needs. [2
