Common Engineering Plastic Material Characteristics
||Applications / Products
||Soft, transparent, non-toxic; low-pressure polyethylene is rigid, wear-resistant, corrosion-resistant, and has good cushion insulating properties.
||High pressure polyethylene:
film, hoses, plastic bottles.
Low-pressure polyethylene: chemical equipment, pipelines, gears and bearings with low load capacity, etc.
||Strength, hardness and elasticity are higher than polyethylene, small woodiness, good heat resistance, excellent pad insulation performance and corrosion resistance.
Poor toughness, not wear-resistant, easy aging.
|Flanges, gears, fungus fan impellers, painted public pipes, containers, medical equipment, etc.
|PVC polyvinyl chloride
||High strength and corrosion resistance. Its body length is high, the product is soft, and the electrical insulation is good.
||Conveyor pipes, centrifugal pumps, ventilators, cable cladding, insulation layers, oil seals.
||High strength, impact toughness, good wear resistance and heat resistance.
High chemical stability and insulating properties.
Good machinability, poor high/low temperature resistance. Flammable and opaque.
|Gears, bearings, dashboard shells, pipes, cabin trim, window frames, sound insulation panels. Aviation and automobile parts.
PA-6 / PA-66
||Excellent mechanical properties, high tensile strength, good toughness, and resistance to repeated impact and vibration. Good abrasion resistance, low friction coefficient, good self-lubrication.
PA-6 has good mechanical strength, electrical properties, impact resistance, abrasion resistance, good toughness, and can absorb noise and vibration.
PA-66 is harder than PA-6 and is suitable for medium size gears.
|Textiles, machine/motorcycle parts, electrical parts, medium-sized gears.
|MC Nylon Steel
||High torsion resistance, wear resistance, and lubricity. Stronger toughness and rigidity.
||Silent gears, guide rails, guide plates, and wear plate parts.
|PEEK Polyether Ether Ketone
||Heat resistance: PEEK is a high-temperature thermoplastic resin, melting point 334 ℃, the long-term use of 250 ℃.
Short-term operating temperature of 300 ℃.
Flexibility: Tops the list of high temperature resistant resins. Flame retardant: UL94V-0 grade self-ignition, low smoke emission.
Chemical resistance: only soluble in concentrated sulfuric acid.
Processability: Good flowability, easy for 2 times processing.
