Semi-products and parts made of engineering plastics Polyplasty

Combination of materials

Polyoxymethylene  + Polyoxymethylene  (POM+PE)

Polyoxymethylene copolymer with approx. 10% of high-molecular-weight Polyethylene. The PE additive acts as a dry lubricant and provides considerably better properties in dry and emergency running.
 
Its low friction coefficient with steel (0.19) is significantly lower than other thermoplastics (PA6 = 0.30 and PP = 0.40). The Polyethylene additive gives quieter operation and self-lubrication for slip bearings. The minimum water intake (0.14 %) provides dimensional stability. Machine parts have good wear resistance and therefore high durability.  Its composition allows it to be used in the food industry . To distinguish it from classical POM it is dyed pale blue.
 

Use of Polyoxymethylene:

  • bearing housing
  • slip plates
  • dynamically loaded construction components

Polysulfone (PSU) and Polyphenylsulfone (PPSU)

They have great strength, hardness and rigidity over a wide temperature range. Can be used continuously at temperatures up to + 180 °C, excellent thermal stability, distortion temperature under heat and creep resistance. They are resistant to hydrolysis, are sterilizable and resistant to gamma-radiation. Theyallow the passage of X-rays. They are translucent and transparent high-temperature plastics that are easily welded. Their electrical properties make them good insulators..
 

Areas of use:

  • medical technology
  • sealing
  • retaining segment
  • piston valve
