Rockeypad specializes in the design and manufacture of high-performance Plastic & Rubber (P+R) keypads, delivering superior tactile response, durability, and aesthetic precision for demanding applications. Our hybrid keypad solutions combine the structural integrity of injection-molded plastic keycaps with the environmental resilience and ergonomic performance of silicone rubber keymats, ensuring optimal functionality across industries.
P+R Keypad Construction & Material Selection
Plastic Key Cap Materials
Keycaps are precision-molded from advanced thermoplastics, selected based on mechanical, environmental, and optical requirements:
– ABS – Cost-effective, impact-resistant, suitable for textured or coated finishes.
– ABS/PC – Enhanced thermal stability and dimensional rigidity.
– PBT – Superior wear and UV resistance, ideal for long-term color retention.
– PC – High-impact strength, excellent for backlit applications.
– PMMA – Optical clarity with high-gloss finish.
– POM – Low-friction, high-wear resistance for high-cycle applications.
Silicone Rubber Keymat
Our compression-molded silicone keymats utilize platinum-cured LSR or solid silicone, ensuring:
– Consistent tactile feedback with controlled actuation force.
– IP-rated sealing (dust/water resistance).
– Chemical, UV, and ozone resistance for extended service life.
Assembly Methods
– Direct Mechanical Assembly – Snap-fit integration for minimal part count and clean interfaces.
– Adhesive Bonding – Enhanced sealing and structural integrity for complex geometries.
