 Product Description

RUBASIA RUBBERTECH INDUSTRIES’ Round EPDM Sponge Cord is a premium-grade closed-cell rubber cord engineered to deliver exceptional sealing, cushioning, and weatherproofing performance in tropical climates like Borneo (Sabah, Sarawak, Brunei).
It is made from high-quality EPDM polymer, offering outstanding resistance to sunlight, ozone, rain, humidity, and temperature fluctuations — ideal for long-term use in both indoor and outdoor sealing environments.

Each roll of RUBASIA’s EPDM sponge cord is uniformly extruded for consistent cross-section, smooth surface finish, and stable compression recovery — ensuring a tight, reliable seal in applications such as windows, doors, hatches, containers, and industrial machinery.

 Detailed Product Features

1. Closed-Cell EPDM Structure

• Fully closed-cell foam design prevents air, dust, water, and gas from penetrating.
• Provides watertight and airtight sealing, even under constant compression.
• Resistant to capillary absorption — moisture cannot pass through the foam.

2. Excellent Weather, UV & Ozone Resistance

• Formulated to withstand extreme UV radiation and ozone exposure common in Sabah’s coastal areas like Kota Kinabalu, Sandakan, Tawau, and Lahad Datu.
• Maintains elasticity under direct tropical sun, high humidity, and salty air — crucial for marine, port, and construction industries in Labuan, Miri, and Bintulu.
• Zero cracking, fading, or hardening over years of use.

3. Superior Temperature Flexibility

• Performs reliably from -40°C (cold storage) to +120°C (industrial heat).
• Ideal for both cold rooms in Kuching food industries and boiler room environments in Sibu and Miri.

4. Chemical and Environmental Resistance

• Resistant to water, steam, weak acids, alkalis, and oxidizing agents.
• Does not support microbial growth — making it suitable for medical and cleanroom sealing in Bandar Seri Begawan, Tutong, and Kuala Belait.
• Non-toxic and environmentally stable with minimal outgassing.

5. Flexible, Soft, and Compressible

• Offers smooth compression and quick recovery — perfect for vibration isolation and cushioning.
• Compressibility makes installation easy on uneven surfaces, window frames, or machine flanges.
• Will not lose its shape or crumble even after prolonged use.

6. High Tensile Strength & Tear Resistance

• Engineered for industrial-grade durability, ensuring strong mechanical performance.
• Maintains dimensional stability under compression and shearing forces — ideal for machinery sealing in Kuching, Bintulu, and Miri factories.

7. Lightweight & Easy to Handle

• Lightweight material makes transportation and installation convenient.
• Can be easily cut to length, joined, glued, or spliced into O-rings or custom seals using standard adhesive bonding.

8. Non-Conductive and Insulative

• EPDM rubber provides excellent electrical insulation properties.
• Used in electrical enclosure sealing and HVAC system gaskets throughout Sarawak’s industrial and energy sectors.

 Technical Performance

 Detailed Applications

1. Construction and Building Sealing

• Window and Door Seals: Prevents water, dust, and air leakage in commercial and residential buildings in Kota Kinabalu, Kuching, and Bandar Seri Begawan.
• Curtain Walls & Glazing Systems: Provides flexible sealing between aluminum and glass systems in high-rise buildings in Miri, Bintulu, and Sibu.
• Roof Hatch Seals & Wall Expansion Joints: Maintains watertight protection during heavy tropical rain in Sandakan and Limbang.

2. Automotive & Transportation

• Applied in car door frames, caravans, truck containers, and trailers.
• Provides dust and noise isolation, suitable for industrial vehicles operating across Borneo’s logging and plantation sectors in Beaufort, Tenom, Kapit, and Betong.

3. Marine & Offshore Applications

• Used for hatch covers, dock fenders, and waterproof hatch seals on vessels in Labuan, Miri, and Bintulu ports.
• Saltwater and UV resistant, ensuring long-lasting sealing on ships, tugboats, and offshore platforms.

4. Industrial and Machinery Use

• Acts as vibration and shock absorber in heavy equipment, compressors, and pumps.
• Prevents air and fluid leakage in industrial tanks and pipe systems across Sarikei, Mukah, and Simunjan.
• Provides protective sealing in electrical enclosures and HVAC ducts in Sri Aman, Serian, and Marudi.

5. Electrical, HVAC, and Refrigeration Systems

• Used in air-conditioning duct joints, chillers, and control panels in Kuching industrial estates and Sabah manufacturing zones.
• Thermal insulation reduces condensation and energy loss.

6. General Sealing and OEM Applications

• Used in custom sealing projects, soundproofing, gasket replacement, and equipment padding.
• Available for OEM manufacturers in Brunei Free Trade Zone, Bintulu Industrial Estate, and Kota Kinabalu Industrial Park (KKIP).

 Installation Guidelines

1. Clean the Surface: Ensure mating surfaces are clean and free from oil, dust, or moisture.
2. Measure & Cut: Cut the EPDM sponge cord to required length using a sharp utility knife.
3. Apply Adhesive (if needed): Use contact adhesive or double-sided tape for bonding.
4. Join Ends: Use rubber adhesive or butt-join techniques for forming continuous seals.
5. Compression Fit: Position the cord into groove or channel, ensuring even compression for perfect sealing.
