Whether you require standard silicone rubber products for industrial electrical equipment or bespoke protective sleeves for smart home controls, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your electronic device protection needs.
Core Features of Our Silicone Rubber Protective Sleeves Our silicone rubber protective sleeves and silicone rubber products stand out for their IP67 waterproof rating, aging resistance, and custom-molded design—key traits that make them ideal for electronic devices, smart home control systems, and industrial electrical equipment.First, the material quality of our silicone rubber protective sleeves is unmatched. We utilize premium silicone rubber (supplemented with EPDM, NBR, and NR options) that achieves IP67 waterproof certification, completely shielding electronic components from dust and water immersion up to 1 meter deep. This formulation also offers exceptional aging resistance, resisting UV damage, oxidation, and temperature degradation (-40°C to 230°C), while adjustable hardness (20~90 ShoreA) balances flexibility for smart home controls and rigidity for industrial electrical equipment protection.Second, custom-molded precision defines our silicone rubber protective sleeves. Our compression moulding process achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber products fit seamlessly over electronic device ports, smart home control buttons, and industrial electrical equipment connectors—eliminating gaps that compromise waterproofing or durability. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber protective sleeves with brand identity without compromising performance.Third, multi-function durability is embedded in every silicone rubber protective sleeve we produce. The robust material composition resists wear, chemical exposure, and mechanical impact, extending the service life of electronic devices and industrial electrical equipment while reducing replacement costs for manufacturers and end-users alike.
