PA nylon / nylon specific viscosity tester

PA nylon / nylon specific viscosity tester
PA6 nylon (Nylon), Chinese name polyamide, English name Polyamide (referred to as PA), is the total molecular chain containing repeated amide groups - [NHCO] - thermoplastic resin collectively.

Nylon has better ageing resistance and mechanical damping capacity, good sliding properties, excellent abrasion resistance, good machining performance, precision for effective control, creeping phenomenon, good wear resistance, good dimensional stability.
Gear and parts for corrosion protection equipment. Wear resistant parts, transmission structural parts, household electrical appliance parts, automobile manufacturing parts, screw rods, machinery parts, chemical machinery parts, chemical equipment, etc..

Nylon 6 (white) has good elasticity, high impact strength and high water absorption. The material has the best comprehensive properties, including mechanical strength, stiffness and toughness, mechanical shock absorption and wear resistance. These characteristics, coupled with good electrical insulation and chemical resistance, make nylon 6 a versatile material for the manufacture of mechanical, structural, and maintainable components.

Nylon 66 (cream) performance is better than that of nylon 6, high strength, good wear resistance, compared with nylon 6, nylon 66 mechanical strength, rigidity, heat resistance and wear resistance, better anti creep properties, but the decrease of impact strength and mechanical damping performance, very suitable for automatic lathe machining.

Nylon 610 is similar to nylon 66 but has little water absorption and low stiffness.

Nylon 1010 translucent, water absorption is small, cold resistance is better.

Viscosity is an important performance index of nylon chips, using Ubbelohde viscometer measurement of viscosity of nylon with high precision, convenient operation.
