Overview:

As the new energy industry rapidly evolves, the demand for high-performance, durable, and safe sealing components has never been greater. Dongguan Chengda Rubber & Plastic Technology Co., Ltd. offers a comprehensive range of rubber and silicone sealing solutions specifically engineered for new energy applications, including electric vehicle (EV) battery packs, charging stations, energy storage systems, and fuel cell assemblies. Our products deliver reliable protection against moisture, dust, vibration, and thermal cycling, ensuring long-term performance in demanding environments.

Key Applications:

• EV battery pack housing seals (IP67 / IP68 rated)

• Charging gun and charging station gaskets

• Fuel cell stack sealing components

• Inverter and converter sealing rings

• Photovoltaic (PV) junction box seals

• Busbar insulation and cushioning pads

Material Options:

We utilize advanced rubber and silicone compounds tailored for new energy requirements:

• Silicone (VMQ): Excellent flexibility at low temperatures (-50°C) and high thermal stability (up to 200°C)

• Fluorosilicone (FVMQ): Superior resistance to fuels, oils, and chemicals for hydrogen systems

• EPDM: Outstanding weather, ozone, and UV resistance for outdoor charging equipment

• NBR / HNBR: High abrasion and heat resistance for mechanical components

Performance Features:

• Excellent dielectric strength and insulation properties

• Flame retardancy (UL94 V-0 / V-1 available)

• Resistance to aging, corrosion, and electrolyte exposure

• Low compression set for long-term sealing integrity

• Customizable hardness (20–90 Shore A) and color coding

Quality Assurance:

All new energy components are manufactured under strict quality control, with 100% dimensional inspection and optional leak testing. Our in-house R&D team can develop custom molds and material formulations to meet specific customer requirements, including RoHS and REACH compliance.

Lead Time & Support:

• Rapid prototyping: 5–7 days

• Mass production: 15–25 days depending on quantity

• Technical support: From design validation to production optimization
