Adhesive Backed EPDM Rubber

D Shaped EPDM Sponge Rubber Seal: Flexible Sealing with Enhanced Compression Performance
Jinjiang Yunli Technology Co., Ltd. presents the D Shaped EPDM Sponge Rubber Seal, an advanced sealing profile designed to deliver reliable performance in applications requiring resilient compression, environmental sealing, and durable weather protection. Its unique D-shaped cross-section combines a flat mounting surface with a softly rounded sealing lip, ensuring effective closure against air, water, dust, and noise.
Made from high-quality EPDM sponge rubber, this seal offers outstanding flexibility, excellent recovery properties, and strong resistance to UV, ozone, temperature extremes (–50°C to 130°C), and aging. The microporous structure enables consistent performance under repeated compression, making it suitable for dynamic and static applications across industries.

• Optimal compression and rebound characteristics
• Superior weather and chemical resistance
• Good sound dampening and thermal insulation
• Self-adhesive or groove-mount installation options
• Customizable in size, color, density, and hardness

Ideal for use in automotive doors, electronic cabinets, industrial machinery, mobile equipment, and architectural glazing, the D Shaped EPDM Sponge Rubber Seal provides a tight and lasting seal even on slightly irregular surfaces. We support full customization-including material compound adjustments, custom-length splicing, and adhesive enhancements-to meet specific customer requirements.
Manufactured under a certified quality system and supported by in-house mold design and material development capabilities, we ensure precision, consistency, and functional reliability in every order. Contact us to discuss your project needs or request complimentary samples.

Adhesive Backed EPDM Rubber: Streamlined Sealing for Modern Applications

Jinjiang Yunli Technology introduces its innovative adhesive backed EPDM rubber, a comprehensive sealing solution that combines the exceptional weather resistance of ethylene propylene diene monomer with advanced pressure-sensitive adhesive technology. This integrated product eliminates the need for separate adhesive application, significantly reducing installation time and ensuring consistent bonding performance across various industrial and architectural applications.

The unique value of our adhesive backed EPDM rubber lies in its sophisticated three-layer construction: a high-quality EPDM substrate, optimized primer coating, and specially formulated acrylic adhesive protected by easy-release liner. This engineered system maintains excellent UV resistance, temperature flexibility (-40°C to 120°C), and long-term weathering capabilities while providing immediate bonding strength upon installation. The adhesive layer demonstrates exceptional compatibility with diverse substrates including metals, plastics, glass, and painted surfaces, ensuring reliable performance in demanding environments.

Technical Advantages:

Immediate adhesion with progressive bonding strength development

Excellent resistance to plasticizer migration and adhesive degradation

Maintains flexibility and sealing performance under thermal cycling

UV-stable adhesive system prevents oozing or shrinkage

Customizable dimensions and adhesive properties available

Application Efficiency:

Transportation Sector: Streamlines sealing applications in automotive, marine, and aerospace industries with reduced labor requirements.

Construction Applications: Provides efficient weather sealing for curtain walls, windows, and door systems with clean installation.

Electronic Enclosures: Ensures reliable gasketing and EMI shielding with simplified assembly processes.

Industrial Equipment: Offers quick sealing solutions for access panels, machinery guards, and housing components.

Our manufacturing process incorporates precision coating technology to ensure uniform adhesive thickness and consistent performance across the entire product surface. Each production batch undergoes rigorous testing for peel strength, shear resistance, and environmental durability according to international standards including ASTM D3330 and PSTC-101.

Available in rolls, sheets, or custom die-cut configurations, this innovative sealing solution represents our commitment to developing products that enhance installation efficiency while maintaining superior performance standards.
