Rubber-Plastic Gaskets
Hybrid components for sealing, damping, and technical assembly
Rubber-plastic gaskets represent an advanced solution for applications requiring not only sealing but also structural rigidity, lightness, chemical resistance, or ease of assembly. RORA designs and manufactures custom parts combining elastomeric compounds with technical plastic inserts or parts through overmolding or co-molding.
Ideal when:
• Plastic provides support, shape, or interface with other components
• Rubber ensures elasticity, damping, sealing, or insulation
Applications:
• Automotive: seals for connectors, cable grommets, quick couplings
• HVAC: anti-noise and anti-vibration gaskets
• Medical and household: tactile interfaces, aesthetic gaskets
• Electronics: IP-rated housing gaskets, insulators
Materials:
• Elastomers: NBR, EPDM, FKM, VMQ
• Plastics: PA (Nylon), POM, PPS, PC, PP, TPE
Strengths:
• Reduced assembly: one component instead of two or more
• Optimized adhesion between rubber and plastic
• Resistance to thermal cycles, vibrations, and chemical environments
