 Ultra-Detailed Product Features

 1. Closed-Cell Structure for Air-Tight & Water-Tight Performance

• Each micro-cell is fully sealed, creating a non-absorbent, impermeable barrier.
• Prevents water leakage, vapor ingress, and dust contamination even under compression.
• Maintains constant seal pressure across irregular surfaces — perfect for marine hatches, outdoor panels, and heavy-duty machinery doors.

 Applications:
Used in Kota Kinabalu, Sandakan, Tawau, Lahad Datu, Labuan, Bintulu, Kuching, and Bandar Seri Begawanfor exterior sealing on marine and architectural projects.

 

 2. Superior UV, Ozone & Tropical Weather Resistance

• EPDM retains elasticity under constant exposure to sunlight, salt air, and humidity.
• Does not crack, fade, or become brittle, even after years of outdoor use.
• Perfect for coastal, offshore, and rooftop installations where other rubbers degrade quickly.

 Common in: Kudat, Sipitang, Kota Belud, Beaufort, Papar, Miri, Seria, and Kuala Belait.

 

 3. Long-Term Durability & Aging Stability

• Chemical structure resists oxidation and ozone degradation.
• Service lifespan up to 10–15 years depending on environment.
• Withstands repeated compression cycles without permanent deformation.
• Retains elasticity and recovery under fluctuating load conditions.

 Used in: Miri, Kuching, Sibu, Bintulu, Limbang, and Bandar Seri Begawan industrial zones.

 

 4. Excellent Thermal Resistance

• Operating range –40°C to +120°C; short-term up to +140°C.
• Suitable for both cold storage insulation and engine compartment sealing.
• No hardening or softening after prolonged temperature cycling.

 Popular for: Refrigeration plants in Kuching, cold rooms in Miri, HVAC ducts in Sibu, and marine engine rooms in Brunei.

 

 5. Vibration Damping & Acoustic Absorption

• Closed-cell foam dampens vibrations and reduces sound transmission.
• Used under machinery, generators, and compressors to absorb shock.
• Prevents metal-to-metal contact and structure-borne noise.

 Installed in: Samalaju, Bintulu, Keningau, Papar, Tuaran, Seria, and Tutong.

 

 6. High Flexibility, Soft Compression & Recovery

• Retains shape after repeated compression cycles.
• Provides soft cushioning without losing thickness.
• Excellent recovery ensures constant sealing pressure.

 Common in: Kota Kinabalu, Ranau, Tambunan, Tenom, and Kuala Belait factories.

 

 7. Non-Toxic & Environmentally Safe

• Free from CFCs, halogens, and heavy metals.
• Non-staining, odorless, and compliant with RoHS & REACH.
• Suitable for food-related and cleanroom applications.

 Used in: Kuching, Sibu, Limbang, and Bandar Seri Begawan food industries.

 

 8. Electrical Insulation Properties

• Non-conductive and dielectric-stable under load.
• Provides insulation between metal surfaces in control panels and junction boxes.
• Protects electronics from moisture and vibration.

 Installed in: Miri, Bintulu, Kuching, and Kuala Belait control room applications.

 

 Installation Methods

1. Surface Preparation: Ensure surfaces are clean, dry, and free from oil or dust.
2. Cutting: Slice cord to required length using sharp utility blade or hot wire cutter.
3. Bonding: For continuous loop seals, join ends with cyanoacrylate adhesive or EPDM rubber glue.
4. Fixing:
   • Insert into channels or grooves, or
   • Apply with double-sided adhesive tape for surface bonding.
5. Compression: When installed, ensure 20–30% compression for optimum sealing pressure.

Easy installation for contractors and maintenance teams in Kota Kinabalu, Kuching, Miri, Sibu, Sandakan, and Brunei.
