# Waterproof Silicone Seal For New Energy Equipment
---
Waterproof Silicone Seals for New Energy Equipment are custom-molded liquid silicone rubber (LSR) components engineered to provide long-term reliable protection against water, dust, humidity, and extreme temperature exposure for critical new energy system components. Manufactured by 橡楚（湖北）橡胶有限公司 at our facility in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, these seals leverage the inherent excellent properties of LSR to meet the harsh operating requirements of new energy generation, storage, and conversion equipment.
Unlike standard rubber seals, our LSR waterproof seals are formulated specifically for the new energy industry, balancing low temperature flexibility, high temperature resistance, weathering stability, and consistent waterproof performance across decades of service. We produce these seals to custom dimensions and hardness requirements based on customer design drawings, ensuring a perfect fit for everything from small power electronics connectors to large battery enclosures and wind turbine hub assemblies. Our core manufacturing focus on liquid silicone rubber products allows us to deliver consistent quality with tight dimensional tolerances, even for high-volume custom orders.

All of our new energy equipment waterproof seals are produced from 100% pure food-contact or industrial-grade liquid silicone rubber, with no recycled filler material. Key material properties include:
Our seals meet the following core physical performance metrics for new energy applications:
Our LSR injection molding process delivers consistent part quality with the following process controls:
---
Our LSR material inherently maintains low water absorption and elastic recovery over decades of service, unlike organic rubber compounds that degrade and crack from prolonged water and UV exposure. The non-porous surface of LSR prevents water penetration even under continuous immersion, maintaining IP68 ingress protection for the full service life of most new energy equipment.
New energy equipment operates across a wide range of environmental conditions, from sub-zero winter temperatures in onshore wind farms to high-temperature environments inside vehicle battery packs and concentrated solar power systems. Our LSR seals retain their elasticity and sealing force at -40°C and resist thermal degradation at continuous 200°C exposure, with no cracking, hardening, or brittling from ozone or UV exposure in outdoor installations.
We produce all seals per customer design drawings and requirements, supporting complex geometries including O-rings, gaskets, lip seals, frame seals, and custom-shaped seals for unique equipment interfaces. Our in-house LSR injection molding capability allows us to accommodate low-volume prototype orders and high-volume production runs with consistent dimensional accuracy.
Our platinum-catalyzed LSR formulations produce low volatile organic compound (VOC) emissions, making them suitable for enclosed new energy systems where outgassing can cause contamination of sensitive electronic components. The material is also non-toxic and RoHS-compliant, meeting global environmental requirements for new energy equipment exports.

Our Waterproof Silicone Seals for New Energy Equipment are suitable for a wide range of new energy generation, storage, and conversion applications, including:
---
The appropriate Shore A hardness depends on your application's sealing pressure and compression requirements:
All of our waterproof seals are custom-manufactured per customer-provided 2D drawings or 3D models, so we do not maintain standard stock sizes. We can produce single-piece seals up to 1200mm in maximum dimension, and segmented seals for larger equipment interfaces that cannot be produced as a single component. Please provide full dimensional tolerances and surface requirement details when placing your order.
We offer two main material grades to match different application requirements:
---
At 橡楚（湖北）橡胶有限公司, we maintain a complete quality management system certified to ISO 9001, with rigorous quality control processes implemented from raw material incoming inspection to final finished product testing. Every batch of raw material is tested for hardness, tensile strength, and elongation before production, and each finished seal undergoes 100% visual inspection and dimensional verification to ensure compliance with customer requirements. For critical application orders, we can provide third-party material testing reports and ingress protection validation reports upon request.
We are 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, focused exclusively on manufacturing high-quality liquid silicone rubber products for industrial and new energy applications.
