Introduction
The new energy industry (including power batteries, energy storage, motor and electronic control, charging stations, lightweight automotive components, etc.) is rapidly developing, placing higher demands on plastic raw materials: high-temperature resistance, chemical resistance, flame retardancy, safety, and lightweight design. For buyers, selecting the right plastic raw material from a vast array of materials directly impacts product performance, cost, and reliability.
01 | Plastic Demand Trends in the New Energy Industry
High Temperature and Electrical Safety: Battery modules and electronic control units require high-temperature resistant and insulating materials to prevent thermal runaway or electrical failure.
Lightweighting: New energy vehicles have strict weight control requirements, making engineering plastics a key metal replacement option.
Flame Retardancy and Environmental Protection: Safety compliance requires meeting flame retardancy standards such as UL94 V0, as well as compliance with environmental regulations such as EU REACH and RoHS.
Chemical Resistance and Long Life: Electrolytes, coolants, and other fluids are highly corrosive to materials, requiring plastics to possess stable chemical resistance.
02 | Recommended Common Plastic Materials for New Energy Applications
In the new energy sector, PPS, PBT, PA, and PC are the main engineering plastics; while PEEK, PPSU, and other materials are higher-end specialty materials, often used in extreme environments or high-reliability scenarios.

03 | Key Applications and Technological Value of Plastics in New Energy
Electric Vehicle (EV) Sector
According to industry estimates, EV in the plastic market scale is expected to about 27% compound annual growth rate (CAGR) .
-Applications include: battery casings (thermal management, flame retardant protection), vehicle interiors, structural support components, and cable insulation.
-Engineering thermoplastics (such as PA, PC, and PPS) provide key support for lightweighting and performance improvements, with the amount of plastic used in EVs reaching approximately 350 kg.
-Thermal management is crucial for plastic housings, reducing vehicle weight by approximately 40 kg and increasing range.
-Innovation Trend: Long-fiber thermoplastic composites are being tested for use in recyclable and replaceable battery structural components.
Photovoltaic and Wind Power Industries
-Glass fiber-reinforced plastic (FRP) is commonly used in wind turbine blades to achieve a balance of strength and weight.
-The transparent covers and light guides in photovoltaic modules are made of materials such as PMMA and PC, which offer excellent optical properties and UV resistance.
-Plastics can also significantly reduce equipment maintenance costs and structural degradation.
Energy Storage and System Infrastructure
-Plastics are widely used in structural components, seals, insulators, and connectors in energy storage power stations and grid components, offering advantages such as corrosion resistance, lightweightness, and weather resistance.
-Emerging Trend: The use of bio-based PE (e.g., derived from sugarcane or corn) can be integrated into existing recycling systems, but industrialization is still a work in progress.
04 | Industry Trends and Sustainable Development
The market for plastics in electric vehicles is growing rapidly: According to market research firms, it is expected to increase from approximately US$4.1 billion in 2025 to approximately US$22.9 billion in 2032.
Recycling and Circular Economy Orientation: For example, Covestro has launched certified recycled PC, and BASF is promoting PU foam recycling, demonstrating a clear trend toward remanufacturing.
Exploring Bio-Based and Degradable Plastics: Materials like PLA and PBAT have entered pilot applications, but are still in the exploratory stage in the new energy sector and have yet to be widely adopted.
