Arnitel®: New concepts for improved keypad performance and cost Arnitel® noise dampening solutions for quality consumer electronics : Low noise gear trains

• Offers better chemical and abrasion resistance
• Higher tear strength, allows for deeper draw ratios in thermoforming and use of thinner films
• Good scratch resistance
• Adheres well to back injected hard materials

Arnitel® buttons for back injection onto PC/PBT or Arnitel® decorative film.

• Excellent adhesion to PET, PC, PC/PBT or Arnitel decorative films
• Softer button has more user appeal
• Lower molding temperature than e.g. PC or PC/PBT avoids wash-out of printing on decorative foil

• Fatigue resistance over broad temperature range maintains original performance
• Low modulus variation with temperature gives user more consistent feel
• Greater design flexibility for enhanced click-through perception

• Integrating all functions into single button component due to greater design flexibility of Arnitel®
• Use of regrind possible, avoids waste, reduces material costs
