Screw Drivers and Plyers Application Data

Benefits

  • Arnitel® TPC allows for reliable solutions due to its retention of flexibility even at temperatures down to -40°C or at elevated temperatures up to 100 ˚C
  • Arnitel® TPC allows for solutions with nice toch & feel characteristics
Virtual Reality Application Data

Details

Different Arnitel grades used in VR headware, combining the excellent skin chemical resistance with comfort, durability and manufacture ability.

Benefits

  • Arnitel® offers high elasticity, low creep and high chemical resistance
  • Arnitel offers excellent bonding to substrates like PC without adhesives
  • Arnitel has no skin sensitivity issues
Spider Couplings Application Data

Details

A spider coupling ensures misalignment in metal shaft connections does not affect the lifetime of the couplers. In essence, the spider coupling dampens the initial hit when the shafts start to rotate.

Benefits

  • Arnitel® offers high load bearing capabilities at high temperature
  • Arnitel ® offers excellent low temperature ductility
  • Arnitel® has good chemical resistance
  • Arnitel® has excellent fatigue properties
Insecticide Bottle Plug Application Data

Details

The plug of the bottle processed from our Arnitel® products give the benefit to be very chemical resistant and to be comfortable.

Benefits

  • Chemical resistance to kerosene
  • Soft material
  • Comfort in PA brush insertion
Support Springs Application Data

Details

Low creep flexing solution for slats and mattresses, creating ultimate sleep comfort by changing durometer per section of your bed.

Benefits

  • Arnitel® has high creep resistance
  • Arnitel® offers a wide range of flexible products, creating the ultimate solution
  • Arnitel® offers easy processing, creating design flexibility
