For new energy lithium batteries, energy storage batteries, two-wheeler batteries, battery packs, BMS modules and battery electronic control units, potting compounds are no longer mere gap fillers. They are functional materials critical to the battery system’s waterproofing, moisture resistance, electrical insulation, shock absorption, flame retardancy, thermal conductivity and long-term reliability.
As new energy batteries raise higher requirements for lightweight design, safety and reliability, domestic potting compound solutions are gaining growing attention. When selecting lithium battery potting compounds, lithium battery foam compounds and other mainstream products, manufacturers should conduct comprehensive evaluation based on battery structure, potting space, weight targets, flame retardant standards, thermal conductivity demands and mass production processes, instead of simply picking products by price.
ELAPLUS Functional Materials (Shanghai) Co., Ltd specializes in electronic adhesives, potting materials, structural adhesives and thermal conductive materials. We deliver a full range of domestic lithium battery potting solutions for new energy vehicles, energy storage, battery packs and electronic modules.

We recommend four core products: PUR 1685AB, SIPA 2100-7#AB, PUR 1680AB and FOAM 8202AB, covering applications such as lightweight foaming, non-foaming low-density filling, thermal conduction & flame retardancy, as well as thermal insulation & shock resistance.
I. Why Price Should Not Be the Sole Criterion for Lithium Battery Potting Compounds
A qualified potting compound does more than fill empty spaces inside battery packs. It provides long-term protection for battery cells, BMS, electronic components, wiring harnesses, connectors and structural parts under harsh operating conditions.
Premium lithium battery potting compounds must meet the following performance requirements:
■ Waterproof & Moisture Resistance
Battery packs and electronic modules often operate in humid, condensing or outdoor environments. Potting compounds effectively prevent moisture ingress.
■ Electrical Insulation
BMS, battery management modules, power controllers and sensors demand excellent insulation to ensure electrical safety.
■ Shock & Vibration Damping
Traction batteries, energy storage batteries and two-wheeler batteries are subject to impacts during transportation and operation. Proper potting materials deliver reliable cushioning protection.
■ Flame Retardancy
Flame-retardant potting compounds serve as an essential safety barrier for new energy battery systems.
■ Lightweight Performance
Traditional high-density potting materials increase overall battery weight. Low-density and foaming potting compounds help achieve weight reduction goals.
■ Thermal Conduction & Heat Dissipation
Certain BMS units, power modules and electronic controllers generate heat during operation, requiring thermally conductive potting materials for effective heat dissipation.
In short, product selection shall be determined by actual application scenarios rather than price or a single performance indicator.
II. PUR 1685: Foamed Polyurethane Potting Compound for Lightweight Battery Potting
Developed for lightweight potting demands, PUR 1685 is a foamed polyurethane potting compound ideal for battery applications requiring weight reduction, gap filling, cushioning and flame retardancy.
Its foamed structure cuts down total weight while providing supportive filling. It is well-suited for battery packs with large internal cavities, strict weight limits and high requirements for shock protection.
Main Applications:
■ Potting for lithium batteries of two-wheelers
■ Lightweight filling inside battery packs
■ Cushion potting for battery modules
■ Foam potting for electronic components
■ Scenarios requiring low density, flame retardancy, moisture resistance and impact resistance
It is an excellent alternative to conventional high-density potting materials for customers looking to adopt domestic lithium battery foam compounds.
III. SIPA 2100-7#: Low-Density Non-Foaming Silicone Potting Compound
For batteries and electronic modules where foaming materials are not applicable but weight reduction is still required, low-density non-foaming potting solutions are the optimal choice.
SIPA 2100-7# is a low-density silicone potting compound featuring light weight and no foaming. It forms a uniform protective layer and delivers flexible protection for electronic components and battery modules, with outstanding performance in lightweight design, flexibility, electrical insulation and thermal stability.
Main Applications:
■ Potting for lithium battery packs
■ Protection for automotive electronic modules
■ Potting for energy storage electronic modules
■ Protection for communication boxes and signal transmission components
■ Scenarios requiring low-stress flexible protection and lightweight potting
It is a preferred low-density silicone potting solution for users seeking weight reduction and stable protection without foaming.
IV. PUR 1680: Thermally Conductive & Flame-Retardant Polyurethane Potting Compound for BMS & Electronic Modules
For BMS, power controllers, sensors and battery electronic modules, potting compounds need to integrate waterproofing, moisture resistance, insulation, thermal conduction and flame retardancy.
PUR 1680 is a thermally conductive and flame-retardant polyurethane potting compound. It features flexibility, effective heat dissipation and flame resistance, tailored for potting and protection of new energy electronic parts.
Key Advantages:
■ Flexible protection to reduce stress on components
■ Thermal conductivity for efficient heat dissipation of electronic modules
■ Reliable waterproofing, moisture resistance and electrical insulation
■ Excellent flame retardancy for new energy electronic applications
Main Applications:
BMS modules, internal electronic parts of battery packs, power modules, controllers, sensors and communication devices. It is one of ELAPLUS’s flagship products for customers demanding thermally conductive and flame-retardant potting compounds.
V. FOAM 8202: Low-Density Foaming Potting Compound for Weight Reduction, Thermal Insulation & Shock Resistance
Foaming potting compounds are widely used for partial cavity filling, enclosure sealing, structural filling, shock absorption and noise reduction in battery packs and electronic equipment.
FOAM 8202 is a foaming potting material designed for low-density filling, equipment sealing, cavity filling and shock protection.
Main Applications:
■ Partial foam filling for battery packs
■ Potting and sealing of electronic equipment
■ Weight-reduction filling for structural cavities
■ Applications requiring thermal insulation, shock resistance and noise reduction
■ Foam potting scenarios with flame retardant requirements
It is a reliable domestic foaming potting solution for battery and electronic structures that combine lightweight design, foam filling, flame retardancy and shock absorption.
