Silicone Rubber Benefits: Silicone rubber is an excellent choice for device operation controls. It possesses the following characteristics: Excellent resistance to both heat and low temperature (-55 to 250 ) Minimum noise generation due to soft and elastic contact structure Minimum abrasion and high resistance to SO2 and oxidation even in heavy humidity Design both tactile and linear feedback Translucent materials available Cost-effective Multi-color designs easily accommodated Water and contamination resistant Main Technique Parameters: Tensile Strength (kg/cm ) 70 Tear Strength (kg/cm) >12 Insulations Resistance 100Mohm at250V DC Contact Resistance 200ohm at 12V DC What kind of rubber keypads LUPHI can do? Different hardness rubber keypads With different shapes carbon printing Color keys rubber keypads Laser etched rubber keypads With soft epoxy on the key surface keypads Second molded keypads With light through pipes keypads Rubber seals P+R (plastic caps plus the rubber keypads) & liquid silicone injection If you want to know more about our silicone rubber keypads services, please feel free to contact us.
