Driven by range anxiety and dual-carbon goals, lightweighting has become a core keyword in vehicle design. A 10% weight reduction can improve driving range by approximately 6%-8%, highlighting the core value of lightweighting for new energy vehicle development.
Advantages of Modified Plastics
- PA66 (Nylon 66): High strength, good heat resistance, used for engine components
- Long Glass Fiber Reinforced PP: Cost-effective, used for body structural parts
- PC/ABS Alloy: Excellent comprehensive performance, used for automotive interiors
- TPE Materials: Combines rubber elasticity with plastic processability, used for seals
Market Data
- Every 100kg weight reduction in traditional fuel vehicles reduces fuel consumption by 0.3-0.6L per 100km
- With new energy vehicles continuously gaining weight, lightweighting demand is urgent
- Replacing steel with plastics has become an important path to automotive lightweighting
Policy Support
The Ministry of Industry and Information Technology's "Petrochemical Industry Stable Growth Work Plan (2025-2026)" explicitly supports R&D of high-end polyolefins, including high melt index polypropylene and metallocene polypropylene, curbing blind expansion of upstream polypropylene raw materials.
