Battery MPP Buffer Pad - Flame-Retardant Foam Insulation Partition for Prismatic cell Batteries

Product Overview

Our Battery MPP Buffer Pad is a high-performance functional material specifically engineered for lithium battery insulation, spacing, and buffer protection. Made from polypropylene (PP) as the base material, supplemented with high-efficiency flame retardants, it is manufactured via clean supercritical carbon dioxide foaming technology, forming a porous structure with numerous micron-sized bubbles inside. This innovative production process ensures the material integrates excellent flame retardancy, thermal insulation, buffer protection, and environmental friendliness, making it an ideal insulation partition and buffer pad for lithium battery packs, energy storage modules, and related new energy equipment.

The buffer pad is made of flame-retardant polypropylene foam, a porous foam material formed by adding flame retardants to polypropylene substrate and using clean supercritical carbon dioxide foaming technology. The internal micron-sized bubble structure endows the material with lightweight, high strength, and excellent thermal insulation and buffer performance, while achieving zero VOC emissions and environmental protection.

• Zero VOC & Eco-Friendly: Clean and non-toxic, zero volatile organic compounds (VOC), fully compliant with ROHS and REACH international environmental standards. Non-crosslinked and recyclable, conforming to green development concepts.
• Lightweight & High Strength: Light weight but high structural strength, density of 40±8 kg/m³, reducing the overall weight of battery packs while ensuring stable buffer and protection performance.
• Excellent Thermal Insulation: Thermal conductivity of 0.041 W/m·K, effectively isolating heat transfer between battery cells, avoiding thermal runaway, and extending battery service life.

Our MPP buffer pad is widely used in new energy battery systems, mainly for:

• Lithium battery packs (lithium-ion, sodium-ion, aqueous zinc batteries) - as insulation partitions and buffer pads, isolating battery cells and absorbing impact.
• Energy storage modules and energy storage equipment - providing thermal insulation and buffer protection, ensuring stable operation.
• Electric vehicle battery packs - internal spacing, shock absorption, and heat insulation, preventing thermal runaway and battery damage.
• Electronic equipment batteries - precision buffer and surface protection, extending battery service life.

• Customization Options: Support customization of thickness, size, density, color, and flame retardant grade according to your drawings, samples, or application requirements, fully matching your battery pack design.
• Quality Assurance: Each batch of products undergoes strict quality inspection, ensuring stable performance, consistent parameters, and compliance with international standards.
• Sample Policy: Free samples available for quality testing and R&D verification (shipping fee borne by the buyer; fee refundable on bulk orders).
• MOQ & Delivery: Flexible MOQ (100 pieces for standard specifications); bulk production lead time 7-15 working days, with fast global shipping via DHL/FedEx/UPS.
• Technical Support: Our professional technical team provides one-on-one consultation, assisting with material selection and application optimization for your specific battery projects.
