# Liquid Silicone Rubber Smart Wearable Accessories
*Manufactured by 橡楚（湖北）橡胶有限公司*

Liquid Silicone Rubber (LSR) smart wearable accessories are custom-molded components designed to meet the demanding requirements of modern wearable electronic devices. At 橡楚（湖北）橡胶有限公司, we produce high-precision LSR accessories that balance comfort, durability, and functional performance for everyday and specialized wearable applications.
Our LSR smart wearable accessories are manufactured from 100% pure medical-grade or food-grade liquid silicone rubber, with consistent material formulation and tight dimensional tolerances controlled through in-house injection molding processes. Unlike generic thermoplastic rubber accessories, our LSR products retain their soft texture, mechanical elasticity, and color stability after thousands of hours of skin contact, repeated bending, and exposure to daily environmental factors including sweat, sunscreen, and mild cleaning agents. We focus on delivering custom-shaped components that integrate seamlessly with mainstream smart wearable designs, from fitness trackers and smart watches to health monitoring patches and wearable medical devices. All our accessories can be tailored to match specific brand aesthetic requirements, with custom color matching, surface textures, and logo integration available.

All materials are free of BPA, phthalates, lead, and other restricted hazardous substances, compliant with REACH and RoHS standards for consumer electronics.

Our LSR accessories have a soft, matte, non-sticky surface texture that does not chafe or irritate skin even during 24/7 wear for health monitoring applications. The material maintains constant elasticity without becoming stiff or brittle in cold weather, and does not get gummy or tacky in high temperatures. Unlike coated fabric accessories, our solid LSR does not absorb sweat or body oils, reducing odor buildup and keeping the accessory clean over long-term use.
We support fully custom molding to match your product’s unique form factor, from small watch seal gaskets and strap keepers to full watch bands, sensor enclosures, and earbud ear tips. We offer a full range of surface finishes, including matte, semi-gloss, and textured options, as well as custom Pantone color matching to align with your brand identity. Our in-house tooling workshop can produce prototype molds in as little as 3 days for design validation, supporting fast product development cycles.
Addition-cured LSR has inherently better resistance to environmental degradation than organic rubbers or lower-quality condensation-cured silicones. Our accessories resist fading, cracking, and performance loss from repeated washing, exposure to UV light, and contact with common personal care products including lotion, sunscreen, and hand sanitizer. The material maintains its mechanical properties for over 3 years of regular use, extending the service life of your wearable device.
LSR has excellent dielectric insulation properties, so it does not interfere with Bluetooth connectivity, heart rate optical sensors, or other electronic functions of smart wearables. For sensor-facing components, we can produce transparent or translucent LSR to allow unobstructed optical signal transmission. The material can also be formulated with anti-microbial additives upon request for added hygiene in prolonged skin contact applications.

Our Liquid Silicone Rubber smart wearable accessories are suitable for a wide range of consumer and medical wearable products:

We do not stock standard one-size-fits-all accessories, as all products are custom molded to match your device’s design requirements. We can produce any dimension from 5 mm small components to 250 mm full watch bands, with multiple size options (e.g., small/medium/large ear tips or watch bands) available to fit different user body types.

At 橡楚（湖北）橡胶有限公司, we implement full quality control processes aligned with our ISO 9001 certification, from raw material incoming inspection to final product outgoing testing. Every batch of raw silicone is tested for hardness, density, and curing performance before production. During manufacturing, we conduct in-process dimensional checks every 2 hours to ensure tolerance compliance. Finished products undergo 100% visual inspection for surface defects, and random sampling testing for physical performance to confirm compliance with specification requirements.
Our manufacturing facility is located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, where we maintain controlled production environments to avoid contamination during molding and post-processing. For any custom order, we provide pre-production prototype samples for your functional testing and validation before full mass production.
