🔍 Material Science & Performance Insight

EPDM sponge rubber is formulated with a saturated polymer backbone that resists degradation by heat, ozone, and sunlight. Unlike natural or neoprene rubbers, EPDM’s molecular structure remains stable in Borneo’s harsh tropical climate, where continuous sunlight, heavy rainfall, and humidity can deteriorate lesser materials.

The closed-cell foam structure prevents the passage of air, water, and dust — ensuring 100% watertight and airtight sealing in outdoor and marine applications. Its flexibility under compression makes it an excellent material for vibration isolation, noise reduction, and shock absorption, particularly in vehicles, machinery, and building structures.

 

🧩 Product Features – Engineered for Performance

1. ✅ Airtight & Watertight Sealing
   Creates a tight seal under compression to block air, water, and dust infiltration in both static and dynamic joints.
2. ☀️ Weather, UV & Ozone Resistance
   Exceptional outdoor durability, ideal for coastal and highland regions of Borneo such as Kota Kinabalu, Kuching, and Bandar Seri Begawan.
3. 🔥 Thermal Insulation & Energy Efficiency
   Reduces heat transfer through walls, panels, or doors — enhancing building energy efficiency.
4. 🔇 Sound & Vibration Damping
   The micro-cell structure absorbs vibrations and reduces noise in machinery, automotive cabins, and marine equipment.
5. 🧲 Non-Conductive Electrical Properties
   Safe for use in HVAC panels, switchboards, generators, and transformers.
6. 💧 Non-Absorbent & Mold Resistant
   Closed-cell foam does not absorb water or support mold growth — essential for humid, coastal regions like Tawau, Sandakan, Miri, and Muara.
7. 🧰 Flexible, Lightweight, and Easy to Install
   Can be bent, compressed, or cut without tearing, making it ideal for onsite sealing and insulation work.
8. ⚙️ Customization Available
   Available in rectangular or square profiles, with optional self-adhesive backing, die-cut shapes, or custom widths and thicknesses.

🧰 Installation Guide

1. Surface Preparation: Clean and dry all surfaces before application. Remove oil, dust, and loose particles.
2. Measuring & Cutting: Mark and cut the EPDM sponge strip to the required size using a sharp utility knife.
3. Adhesive Application (if required):
   • Use double-sided adhesive tape for easy installation.
   • For heavy-duty use, apply contact adhesive or silicone bonding agent.
4. Compression Fit: Press the strip firmly along the sealing line, ensuring continuous contact and no air gaps.
5. Inspection: Verify uniform compression and check for water or air leaks after installation.
