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.
Main Features:
- 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.
