Product Description
EPDM Rubber Seal Strip: Versatile Sealing for Diverse Industrial Applications
Jinjiang Yunli Technology Co., Ltd. specializes in the production of high-quality EPDM rubber seal strip, a resilient and durable sealing solution designed to perform in a wide range of environmental and industrial conditions. Engineered from premium ethylene propylene diene monomer, this seal strip offers outstanding resistance to aging, ozone, UV exposure, and temperature fluctuations, making it suitable for both indoor and outdoor applications.
With excellent compression set recovery and well-balanced physical properties, our EPDM seal strip effectively prevents the leakage of air, water, dust, and noise. It is available in various profiles, including hollow, solid, and magnetic designs, to meet different functional and installation requirements.
Key Features:
Superior weather and temperature resistance (–50°C to 150°C)
Good elasticity and tear resistance
Customizable shapes, hardness, and colors
Options with or without self-adhesive backing
Resistant to water, chemicals, and oxidation
This EPDM rubber seal strip is widely used in automotive door and window seals, electrical cabinets, HVAC systems, industrial machinery, and construction joints. We support custom orders based on provided samples or technical drawings, including adjustments in compound formulation, size, and adhesion type to align with specific project needs.
Our production process integrates advanced extrusion and vulcanization technologies, supported by strict quality control in accordance with ISO 9001 standards. We are committed to delivering consistent performance and reliability in every batch.
Whether you are looking for standard or customized sealing solutions, Yunli provides professional technical support and timely service. Contact us today to request product samples or discuss your sealing requirements.
Main Features:

FAQ: EPDM Rubber Seal Strip
Q1: What are the primary advantages of using EPDM for seal strips compared to other elastomers?
A: EPDM offers superior resistance to weathering, ozone, UV radiation, and extreme temperatures, maintaining flexibility from -50°C to 150°C. Unlike natural rubber or PVC, it doesn't harden or crack over time, ensuring long-term sealing performance with minimal maintenance.
Q2: Can these seal strips be used in electrical or conductive applications?
A: Standard EPDM is an electrical insulator. If conductivity is required, we can develop custom compounds with conductive additives to meet specific surface resistance requirements for specialized applications.
Q3: How does your EPDM rubber seal strip perform in low-temperature environments?
A: Our EPDM material retains excellent flexibility and sealing capability even at -50°C, making it suitable for cold storage facilities, refrigeration units, and outdoor applications in cold climates without becoming brittle.
Q4: Are there eco-friendly or food-grade options available?
A: Yes. We offer food-grade EPDM compounds compliant with FDA 21 CFR 177.2600 and EU regulations, free from heavy metals and harmful substances. All our EPDM strips are REACH and RoHS compliant.
Q5: What installation methods do you support for these seal strips?
A: We provide multiple installation options: self-adhesive versions with strong acrylic adhesive, groove-mounted designs for channel insertion, and magnetic strips for metal surfaces. Custom clamping systems can also be developed.
Q6: How do you ensure consistency in strip dimensions and performance?
A: We utilize precision extrusion equipment with laser measurement systems and implement SPC (Statistical Process Control) throughout production. Every batch undergoes dimensional checks, hardness tests, and compression set verification.
Q7: Can you create custom profiles for unique applications?
A: Absolutely. Our engineering team can develop custom die designs for specialized profiles. We typically require dimensional drawings or samples, and can produce prototypes for validation within 5-7 working days.
Q8: What is the maximum continuous length available for these strips?
A: We can produce continuous lengths up to 100 meters per piece, with consistent cross-section and performance throughout. Longer continuous lengths can be accommodated for specific project requirements.
Q9: Do you provide color-matching services for aesthetic applications?
A: Yes. While black is standard, we offer color-matching capabilities for white, gray, and custom colors to meet architectural or design requirements, with UV-stable pigments to prevent fading.
Q10: What technical documentation can you provide with the products?
A: We supply comprehensive documentation including material certification, test reports (physical properties, aging resistance), compliance certificates (RoHS, REACH), and installation guidelines upon request.
