Silicone Button Membrane, also known as Rubber Membrane Buttons, Silicone Rubber Membrane Keypad & Keyboard, and Rubber Membrane Keyboard, is crafted from a clear elastomeric silicone rubber material. Utilizing either silicone button compression molding or liquid silicone rubber (LSR) injection molding, these membranes find extensive applications in electronic keypad switches, remote control device buttons, and various medical and machinery devices.

Manufacturing Process
- Material Preparation: Start by preparing high-clarity elastomeric silicone rubber material.
- Initial Vulcanization: Perform the first vulcanization process through compression molding to create the base of the silicone rubber button pad.
- Color Application: Apply black and white color coatings to achieve the desired visual appearance.
- Laser Etching: Use laser technology to etch characters onto the surface of the buttons, ensuring precision and clarity.
- Silkscreen Printing: Apply silkscreen printing for detailed and intricate designs, enhancing the visual aesthetics of the buttons.
- Polyurethane Coating: Apply a PU polyurethane coating to the surface, providing durability, resistance, and a smooth finish.
- Epoxy Coating: Apply an epoxy coating on the keys, enhancing their resilience and longevity under various conditions.
- Burr Removal: Perform a die-cut process to remove any burrs or imperfections from the silicone button membrane, ensuring a seamless and polished final product.
- Adhesive Layer Application: Apply a 3M adhesive layer to facilitate easy and secure attachment of the silicone button membrane in the intended devices or applications.
Conductive Silicone Button Membrane:
- Variants: Silicone Button Membrane comes in conductive and non-conductive types.
- Non-Conductive Variant: Non-conductive Silicone Membrane Keyboard Covers serve as keycaps for electronics without conductivity. They enable backlighting by placing LEDs under the silicone pad, or via techniques like laser etching.
- Conductive Variant: Silicone Rubber Button Pads with conductivity employ methods like conductive ink printing, carbon pills, metal dome, metal pills, and nickel pills under keys. Different methods have varying resistance levels, allowing customers to choose based on specific keypad applications. Conductive ink printing and carbon pills are common solutions for conductivity.
