Fast Shipping Silicone Keypad with Durable PU Coating
A PU-coated silicone keyboard, also known as an oil-coated silicone keyboard, features a protective layer that enhances durability and safeguards symbols and characters from wear. This coating provides a smooth, matte surface, offering a pleasant texture and a professional finish. It is commonly applied to keyboards with screen-printed icons and graphics, as well as to laser-etched silicone keyboards for additional protection. This ensures the longevity and resilience of the keyboard’s printed elements.
Surface Protection Options for Rubber Keypads:
1.PU (Polyurethane) Coating: Offers exceptional durability and robust protection, surpassing that of traditional oil coatings, ensuring extended performance life.
- Epoxy Coating: Features a transparent resin layer that delivers a clear, visually appealing finish, enhancing the aesthetic of the rubber keypad.
- Plastic Keycaps: Provide excellent protection and durability, although they are more costly to produce due to the complexity of the molding process.
- Oil Coating: A cost-effective solution for keypad manufacturing, though it lacks the durability of PU or epoxy coatings.
Surface Treatments:
– Oil and PU Coating: Create a matte finish for a smooth, tactile experience.
– Epoxy Coating: Offers a glossy, clear surface that enhances visual appeal.
These treatments are engineered to prolong the lifespan of your keyboard, protect surface icons or graphics, and maintain the vibrant colors of silicone buttons.
Classification of Silicone Buttons by Conductivity:
Silicone rubber keyboards vary not only in surface finish but also in their conductive mechanisms. They can be classified into four types based on their conduction methods:
1.Carbon Pill Silicone Keyboards: These utilize carbon pills under the rubber buttons, offering reliable conductivity and extended lifespan.
2.Conductive Ink Silicone Buttons: Employ conductive ink for efficient conduction, providing a cost-effective solution.
3.Gold Pill Silicone Keyboards: Feature gold pills, known for their low resistance and suitability for precise, high-performance applications.
4.Metal Dome Rubber Keyboards: Use metal domes for conductivity, delivering tactile feedback and excellent durability.
Each type of conductive silicone keyboard is chosen based on specific resistance requirements, with carbon pill keyboards noted for their lower resistance and longer lifespan compared to conductive ink keyboards.
