ET rods are milky white or pre-yellow highly crystalline polymers with a smooth and shiny surface. Good creep resistance, fatigue resistance, friction resistance and dimensional stability, low wear and high hardness, with the greatest toughness among thermoplastics ; good electrical insulation performance, little affected by temperature, but poor corona resistance.
Non-toxic, weather resistance, good stability against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water soaking, not alkali resistant.
The main characteristics of PET sheet:
High
mechanical strength , rigidity and hardness. Good sliding properties and
wear strength , good electrical
insulation , very good creep resistance, low and stable coefficient of friction Excellent
wear resistance (better than
nylon ), very good
dimensional stability (better than POM), physiologically inert (suitable for food contact).
Weather resistance ,
chemical resistance, good stability, low
water absorption ,
weak acid and
organic solvent resistance, but not hot water immersion resistance, not alkali resistance.
Widely used in textile, paper,
food machinery , transportation, wharf, medical, coal mine, chemical and other industries. Bearings, guide food processing machine heads, pistons, screw rolls and other food fixtures, parts, bearings for precision machines, electrical
insulation materials , etc.
