Single-Sided Adhesive Barley Paper - Flame-Retardant, High-Temp Resistant Insulation Gasket for Batteries

Our single-sided adhesive barley paper is a specialized insulation gasket engineered exclusively for lithium batteries (such as 18650 models) and electrical equipment. Crafted via fluoroplastic processing, this paper-based material combines exceptional insulation performance with superior durability, making it an essential component for enhancing battery safety and reliability. Designed with a pre-applied single-sided adhesive, it enables quick, hassle-free installation without extra tools, perfectly fitting battery packaging and component spacing needs.

As an eco-friendly, flame-retardant insulation material, it is tailored to address core safety concerns in battery applications. Whether used as a spacer between hard metal parts or a gap-sealing component, it delivers consistent protection against short circuits and thermal hazards, becoming a trusted choice for battery manufacturers, electronic device producers, and DIY energy enthusiasts worldwide.

Barley paper is a fluoroplastic-processed paper product widely utilized in electrical and mechanical equipment. Its unique composition grants it a suite of performance advantages that make it ideal for insulation and gap-filling scenarios:

• Excellent Insulation: Blocks electrical conduction effectively, preventing short circuits between metal components.
• Superior Flexibility & Durability: Flexible enough to fit irregular surfaces, with outstanding water resistance, wear resistance, oil resistance, and anti-aging properties for long-term use.
• Ideal Gap Filler: Seals gaps between hard metal parts tightly, avoiding friction and contact-induced damage.

For lithium batteries (especially 18650 models), barley paper serves as a critical safety barrier, with two core purposes:

1. Prevents battery self-ignition caused by short circuits, mitigating fire and explosion risks in battery packs.
2. Significantly enhances overall battery safety, ensuring stable operation in various working environments (e.g., portable power stations, electric tools, and consumer electronics).

• Single-Sided Adhesive Design: Pre-applied, high-tack adhesive enables easy, quick installation. No additional glue or tools required, improving assembly efficiency and reducing production costs.
• Flame-Retardant & Eco-Friendly: Adopts flame-retardant technology, meeting strict safety standards to inhibit fire spread. Non-toxic, eco-friendly materials comply with global environmental regulations.
• High-Temperature Resistance: Maintains stable performance under high-temperature conditions, adapting to the heat generation of battery operation and harsh working environments.
• Battery-Specific Customization: Tailored for 18650 and other lithium battery models. Supports customization of size, thickness, and adhesive strength to match diverse battery packaging needs.
• Multi-Scene Versatility: Beyond batteries, it is widely used as an insulation spacer in electrical appliances, mechanical equipment, and automotive electronics, delivering reliable performance across industries.
