Thermoplastic Polyurethane (TPU) Keypad

Thermoplastic Polyurethane Keypad

This keypad has the soft feel of TPU (Thermoplastic Polyurethane). This TPU film is formed using a co-molding process with silicone rubber. It is similar to IMD (In Mold Decorating) but has a softer feel than is available with PET films generally used in IMD keypads. TPU film cannot be formed with deep draws like PET films used in IMD keypads. Thus they are ideal for thin keypads used in small hand held devices. The TPU material has superior abrasion resistance and is resistant to chemicals and UV lighting.

Keypads are constantly in contact with fingers, which can transmit dust and other contaminants, and that also means the keypad is constantly coming into contact with the oil from those fingers. If the product comes into contact with the face, there are oils that are transmitted to the keypad there as well. Thanks to excellent the chemical resistant qualities of TPU, these oils will not adversely affect the keypads. The keys can last longer and resist premature aging, corrosion, and the constant wear and tear of daily use.

This particular keypad s co-molded with a metal frame for stiffness and assembly operations.
