Rubber keypads and silicone rubber keypads, has successfully replaced traditional mechanical switches for decades. Silicone rubber keypads are easily-implemented, cost effective, reliable and most important of all, it can produce excellent tactile responsiveness. Silicone rubber keypads, can perform very well even under extremely high or low temperature. Applications: mobile phones, calculators, hand-held games, PCs, notebook computers, swithches, remote controls, databanks, toy games, micro measurement equipment, typewriters, cordless phones All shapes and colors available for custom designs silicone rubber keypads and rubber keypads.

Common Fillers and Their Effect on PTFE

• Glass : The most common filler, minor effect on electrical properties, increased abrasion on mating metal surfaces.
• Carbon : Low abrasion and wear, good deformation and extrusion resistance.
• Graphite :Non-abrasive, low friction, minor effect on deformation properties.
• MoS2 : Lowers break-in wear and starting friction.
• Bronze : Very high wear resistance and load bearing capability. Poor chemical resistance.
• Stainless Steel : High wear resistance and load bearing capability. Wider chemical resistance than bronze.
• PPS : Low wear and abrasion, excellent deformation and extrusion resistance. Large reduction in tensile and elongation values.
• CaF2 : Hydrofuoric acid service.
• The most common filler, minor effect on electrical properties, increased abrasion on mating metal surfaces.
