Soft Touch in Spatulas and Kitchenware Application Data

Details

Arnitel® has low viscosity grades which give excellent flow behavior for 2K-molding .

Benefits

Arnitel® TPC allows for reliable solutions because of its excellent adhesion with PBT in 2K injection molding, its superb scratch resistance (which make kitchen tools look better even after years of intensive usage), its chemical resistance (dish washer proof) and its approvals for direct food contact
Wine Taps Application Data

Details

The Wine Tap is used in bag and boxed wine packaging for distributing wine.

Benefits

  • Arnitel® has FDA approval for high alcohol contents and single use
  • Arnitel® offers good elasticity and low hysteresis, resulting in good spring characteristics
  • Arnitel® has good colorability with a stable white base color
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
DC Cables Application Data

Details

DC Cables are generally used for standard electronics charging systems, like adapters. The latest designs can also be used for USB-C charging, leading to much thinner cables than AC with similar charging and safety characteristics.

Benefits

  • Arnitel® has a proven track record in wire and cable, also in ultra thin cables in all application areas
  • Arnitel® offers a long history in commercial production and use in major electronics OEM
  • Arnitel® solutions are known to most cable extrusion companies
  • Arnitel® is easy to color with consistent haptics
Outdoor Consumer Cables Application Data

Details

Thin low voltage consumer electornics cabling, used in the outdoor environment to accommodate the use of electronics in the field, i.e. camera's, sensors etc.

Benefits

  • Arnitel® Wire & Cable grades exceed the UL758 for signal, AC and DC applications
  • Arnitel® offers most colors possible without strong discoloration in UV
  • Arnitel® has a long track record in outdoor applications
Phone Case Application Data

Details

Product designers and manufacturers increasingly rely on thermoplastic elastomer (TPE) material solutions to produce and deliver highly durable and high-quality soft touch parts. Compared to the thermoplastic polyurethane (TPU) materials traditionally used for soft-touch manufacturing, TPEs offer better resistance to warpage and fatigue, as well as better protection against UV, chemical, and oil exposure.

Benefits

  • Broad tactile properties with superior touch and feel
  • Broadest operating temperature range from -45°C to 150°C
  • High tear and abrasion resistance
  • High fatigue endurance after 255 compression cycles
Grips Application Data

Details

Grips are applicable to consumer appliances such as kitchenware, household utensils, hand tools, game controllers and much more. The material is usually overmolded on PC, PC/ABS or polyester.

Benefits

  • Arnitel® allows for excellent bonding in molding on miscellaneous in thin walls
  • Arnitel® solution is dish washer proof and has good grease resistance
  • Arnitel® solution offers good haptics
Arnitel Spring in Monitor Arm Application Data

Details

Adjustable load bearing for monitor arm

Benefits

  • Elasticity
  • Low creep
  • Adjustable load bearing
