Serving All Industrial, Construction & Marine Sectors in Sabah, Sarawak & Brunei

 

 High-Performance Closed-Cell EPDM Rubber Cord for Sealing, Cushioning & Insulation

RUBASIA RUBBERTECH INDUSTRIES manufactures and supplies premium Round EPDM Sponge Cords designed for high-performance sealing, weatherproofing, and vibration absorption.

Constructed from Ethylene Propylene Diene Monomer (EPDM) — a synthetic rubber formulated to endure harsh tropical weather, salt air, and UV exposure — this product delivers exceptional reliability across industrial, marine, automotive, and building applications in the humid and coastal environments of Sabah, Sarawak, and Brunei.

 

 Product Construction and Material Composition

• Base Polymer: Ethylene Propylene Diene Monomer (EPDM)
• Cell Structure: Fully closed-cell, non-porous and impermeable
• Density: 0.15 – 0.25 g/cm³ (lightweight yet durable)
• Hardness: 15 – 25 Shore A
• Compression Set: Excellent recovery after long-term compression
• Color: Black (standard) — available in grey, white, or custom colors upon request
• Temperature Range: –40°C to +120°C continuous use
• Water Absorption: < 5% (nearly waterproof)
• Flame Resistance: Optional flame-retardant grade available
• UV Resistance: Excellent, even in direct sunlight
• Chemical Resistance: Resistant to acids, alkalis, salts, steam, and polar chemicals
• Electrical Insulation: Non-conductive and dielectric stable

 

 Detailed Product Features

1  Closed-Cell Air & Water Seal

• Each cell is individually sealed, preventing air, moisture, and dust penetration.
• Ensures a tight, compressible seal between two surfaces.
• Ideal for airtight and watertight sealing under compression in window and door frames, equipment housings, and marine hatch covers.
• Prevents rust, corrosion, and contamination caused by humidity or sea spray.

 Commonly used in humid areas like Kota Kinabalu, Sandakan, Tawau, Lahad Datu, and Labuan.

 

2  Superior Weather & UV Resistance

• Withstands continuous tropical exposure — rain, sunlight, and ozone — without hardening or cracking.
• Maintains flexibility even after long-term outdoor installation.
• Performs well in coastal climates and mountainous regions with variable humidity.

 Ideal for outdoor sealing in Miri, Kuching, Sibu, Bintulu, Seria, and Bandar Seri Begawan.

 

3  Excellent Flexibility and Elastic Recovery

• Retains shape and elasticity after repeated compression cycles.
• Provides a soft yet firm compression seal.
• Performs effectively across temperature extremes from freezing to hot, sunny climates.
• Prevents material fatigue in moving or vibrating systems.

 Performs well in dynamic environments like Papar, Tuaran, Ranau, and Keningau.

 

4  High Vibration & Shock Absorption

• Functions as an anti-vibration cushion in machines, motors, compressors, and vehicles.
• Reduces noise and mechanical stress in structural joints or mounting surfaces.
• Used in both light-duty machinery and heavy industrial equipment.

 Popular in industrial estates in Samalaju, Bintulu, and Senadin (Miri).

 

5  Excellent Ozone, Steam & Chemical Resistance

• EPDM is naturally resistant to ozone cracking, oxidants, and mild acids or alkalis.
• Withstands exposure to steam and cleaning agents commonly used in processing plants.
• Non-toxic and non-marking, safe for use in sensitive environments.

 Preferred in food and chemical factories in Kuching, Sibu, Limbang, and Brunei (Muara, Tutong).

 

6  Thermal and Acoustic Insulation

• Provides sound and vibration isolation for HVAC, compressor rooms, and control panels.
• Acts as a thermal barrier, reducing heat transfer between surfaces.
• Non-conductive — ideal for electrical cabinet sealing.

 Used widely in electrical and mechanical facilities in Miri, Kuching, and Kuala Belait.

 

7  Long Service Life & Easy Installation

• EPDM sponge cords are lightweight, flexible, and easy to handle.
• Can be cut to desired lengths and bonded using rubber adhesive or contact cement.
• Offers service life exceeding 8–10 years under normal outdoor conditions.

 Installed in commercial and residential projects across Kota Kinabalu, Sibu, and Bandar Seri Begawan.
