In recent years, the global new energy battery industry has expanded rapidly. At the same time, governments are tightening regulations on safety and environmental performance.
From the EU Battery Regulation’s strict requirements on carbon footprint and recyclability, to China’s GB 38031 safety standards for thermal runaway and mechanical impact, and UN 38.3 transportation standards—every regulation is pushing material innovation throughout the supply chain.
For battery system manufacturers, this means that materials can no longer be seen as simple “supporting components.”
They must now actively enable compliance, safety, and performance to help OEMs and battery producers pass certification and achieve mass production.
Battery modules must withstand needle puncture, extrusion, and impact without structural failure.
Materials need to balance lightweight design with sufficient compressive and cushioning strength.
The EU Battery Regulation requires recyclability and circular use.
Traditional cross-linked foams face recycling challenges, while low VOC, RoHS/REACH compliance has become a global entry standard.
Battery pack weight directly affects EV energy efficiency and driving range.
Demand for lightweight materials continues to rise in EV design.
Polypropylene Microporous Foam (MPP) is produced using supercritical CO₂ clean foaming technology, forming a uniform microcellular structure that combines strength and lightweight performance.
Under the new regulatory framework, MPP shows distinct advantages compared to traditional foams:
Non-crosslinked system – recyclable and reusable, compliant with EU circular economy goals.
RoHS/REACH compliant, low VOC emissions, suitable for battery modules and vehicle interiors.
Excellent impact absorption under needle penetration and extrusion tests.
Ideal for cell spacers, module side pads, and battery base supports.
Balances light weight and mechanical integrity.
Low density, replacing rubber or engineering plastics to reduce overall battery weight.
In long-range EV designs, lightweight materials translate directly into extended range and energy savings.
Excellent resistance to electrolytes and common chemical media.
Ensures long-term structural stability in harsh or cyclic environments.
Between prismatic cells: Serves as a spacer to prevent direct collision during impact tests.
Module side cushioning: Reduces deformation and structural damage during international extrusion tests.
Battery pack base support: Provides both load-bearing and energy absorption functions.
Defense and high-end energy storage: Ensures reliability in extreme temperature and mechanical conditions.
The global direction of new battery regulations is clear: safer, greener, and lighter.
Within this framework, MPP (Polypropylene Microporous Foam) stands out with its non-crosslinked recyclability, excellent cushioning, lightweight design, and chemical resistance, making it an ideal material for next-generation EV battery modules and packs.
For both battery manufacturers and automotive OEMs, MPP is not just a material to pass compliance tests—
it represents a long-term sustainable solution aligned with the future of the energy and mobility industry.
