New energy equipment, such as photovoltaic mounting systems, outdoor charging stations, and energy storage cabinets, is mostly deployed on rooftops, rural roads, and other locations where maintenance is difficult. The equipment is continuously exposed to intense sunlight, diurnal temperature fluctuations, and weathering from wind and rain, placing demands on the accompanying elastomeric materials for long-term stability and reliability. Weather-resistant TPE extrusion particles combine sealing elasticity, outdoor weather resistance, and extrusion processing advantages, making them a practical elastic material for outdoor new energy equipment.

1. Charging Station Cable Sheaths and Connector Seals

Charging station cable sheaths and connector seals are among the most representative application scenarios for weather-resistant TPE extrusion particles. Charging cables undergo repeated plugging and unplugging, dragging, and crushing on a daily basis, and are exposed to UV radiation year-round. Ordinary elastomers tend to harden and crack after prolonged outdoor use. Once the sheath is damaged, the inner insulation loses its protection. Weather-resistant TPE extrusion particles incorporate light stabilizers and antioxidant systems into their formulations to slow down UV-induced molecular aging and maintain the material's flexibility over the long term. Relying on the material's resilience, the charging gun's sealing ring maintains a tight seal even as temperatures fluctuate, reducing the ingress of moisture and dust into the charging port.

2. Outdoor Energy Storage Cabinets and Portable Power Supplies

The sealing and cushioning components in outdoor energy storage cabinets and portable power supplies place particular demands on the material's hydrolytic stability and low-temperature performance. Temperature fluctuations inside energy storage cabinets are significant, so sealing strips must maintain their shape and elasticity consistently under these variable conditions. Even in low-temperature environments, weather-resistant TPE extrusion particles retain good flexibility, making them suitable for outdoor use in northern regions. Long, strip-shaped components, such as cable outlet sleeves and handle cushioning pads, can be continuously produced as profiles using the extrusion process, allowing for simple cutting and assembly, which is suitable for large-scale production.

3. Photovoltaic Accessories

Sealing strips for photovoltaic junction boxes and protective strips for frames are constantly exposed to intense sunlight. Weather-resistant TPE extrusion particles undergo outdoor natural exposure testing to evaluate their durability. Compared to laboratory-based accelerated aging data alone, this method more closely simulates real-world outdoor conditions, supporting the long-term stable operation of photovoltaic components.

4. New Energy Vehicle Exterior Components and Charging Connector Peripherals

This material is also increasingly being adopted for water-diverting strips on new energy vehicle exteriors and seals around charging connectors. The material is compatible with overmolding onto PP substrates, balancing weather resistance with low-temperature flexibility. The long-profile extrusion process offers stable production, controllable finished dimensions, and good surface quality.

Key Considerations for Material Selection

During the material selection phase, several indicators need to be verified: performance retention data after UV aging, the ability to maintain elasticity in low-temperature environments, the bond strength between the overmolded material and the rigid polymer substrate, and long-term hydrolytic stability in humid environments.

Overall, the advantage of weather-resistant TPE extrusion particles lies not in the exceptional performance of any single property, but in the integration of elastic sealing, weather resistance, and processing convenience. In applications such as charging stations, energy storage equipment, photovoltaic components, and exterior trim for new energy vehicles, suitable raw materials support the long-term operation of outdoor equipment, reduce future maintenance needs, and provide a solid material foundation for new energy outdoor equipment.
