Specifications
Details
๐งฉ 1. Closed-Cell Foam Technology (Non-Absorbing Structure)
- EPDM sponge is created using closed-cell foaming technology, where millions of tiny independent air bubbles are encapsulated within the rubber matrix.
- Each microcell is completely sealed, forming a non-porous, waterproof barrier.
- This structure prevents water, air, dust, or oil penetration, making the strip ideal for external sealing, marine exposure, and air-conditioning duct systems.
- It delivers low water absorption (<1% by volume) even under continuous immersion.
๐ Key Advantage: Maintains long-term watertight and airtight performance in high-humidity areas like Kota Kinabalu, Miri, Kuching, and Bandar Seri Begawan.
โ๏ธ 2. Advanced Weather, Ozone & UV Resistance
- EPDM’s molecular backbone is saturated and crosslinked, making it inherently stable against ozone cracking, oxidative aging, and UV radiation.
- Unlike natural or SBR rubber, EPDM will not chalk, harden, or lose elasticity even after years of exposure to tropical sun.
- Tested to withstand >1,000 hours in UV chamber without surface degradation.
- Maintains tensile retention >90% after prolonged outdoor exposure.
๐ Key Advantage: Delivers long-term outdoor service life for building facades, marine vessels, and automotive weather seals across coastal and inland towns.
๐ก๏ธ 3. Wide Service Temperature Range
- Functional temperature span: -40°C to +120°C continuous, with short-term peaks up to +150°C.
- Retains flexibility and compression recovery even at freezing conditions (tested to -40°C with no surface cracking).
- Stable mechanical performance at elevated temperatures without softening or melting.
๐ Key Advantage: Performs consistently across extreme environments — from cold storage insulation in Miri to roof seals under direct sunlight in Kuching.
๐ช 4. High Elasticity and Compression Recovery
- Compression deflection at 25%: typically 35–70 kPa, ensuring a soft yet resilient seal.
- Compression set after 22 hours at 70°C: <15%, meaning the material rebounds effectively to its original shape.
- Engineered for dynamic compression cycles, such as door gaskets or vibration isolation pads.
๐ Key Advantage: Prevents permanent flattening, ensuring consistent sealing pressure over years of repeated use.
โ๏ธ 5. Dimensional Stability & Low Shrinkage
- Formulated with precision extrusion control to achieve uniform density (0.35–0.7 g/cm³).
- Exhibits <2% dimensional variation over time, even with temperature fluctuations or mechanical compression.
- Ideal for tight tolerance installations such as enclosure doors, HVAC ducts, and machine housing joints.
๐ Key Advantage: Guaranteed dimensional accuracy for OEM and industrial fitting applications.
๐ 6. Acoustic & Vibration Absorption
- The internal closed-cell structure and micro-elastic walls effectively absorb sound waves and mechanical vibrations.
- Sound absorption coefficient up to 0.35 (at 1000Hz).
- Reduces transmission of vibration through surfaces and minimizes rattling noises.
๐ Key Advantage: Improves acoustic comfort and machinery stability in industrial facilities and vehicle interiors.
๐งฒ 7. Non-Conductive Electrical Insulation
- Volume resistivity exceeds 10¹โฐ Ω·cm, confirming its excellent electrical insulation property.
- Does not contain conductive fillers such as carbon black that could create short paths.
- Used widely in HVAC systems, electrical cabinets, switchboards, and air-conditioning ducts.
๐ Key Advantage: Provides safe electrical isolation in high-voltage or electronics-related environments.
๐ง 8. Chemical and Fluid Resistance
- Resistant to mild acids, alkalis, salts, detergents, oxidizing agents, and antifreeze fluids.
- Not affected by exposure to steam, diluted chemicals, or ozone-treated air.
- Non-reactive to detergent mists or cleaning fluids commonly found in food plants or marine docks.
๐ Key Advantage: Ideal for chemical plants, laboratories, and maintenance areas across Bintulu, Sibu, and Seria.
๐ฆ 9. Microbial & Mold Resistance
- Non-organic closed-cell structure prevents absorption of moisture, eliminating conditions that promote fungal, bacterial, or algae growth.
- Tested under ASTM G21 fungal resistance standards – passes with zero fungal growth after 28 days.
- Ensures odor-free and hygienic performance in enclosed or humid environments.
๐ Key Advantage: Excellent for air-conditioning insulation, cold storage gaskets, and marine interiors.
๐ฅ 10. Optional Flame Retardant Grade (FR-EPDM Sponge)
- Available in flame-retardant formulations meeting FMVSS 302 and UL 94 HF-1 standards.
- Low smoke and low toxicity emission during combustion.
- Used for railway, automotive, marine, and electrical enclosure applications.
๐ Key Advantage: Enhanced safety for high-risk or confined environments.
๐งด 11. Surface Finish & Aesthetic Uniformity
- Smooth, fine-textured skin on both sides formed during extrusion for professional visual appearance.
- Color options: standard black, optional grey or custom colors for OEM or aesthetic applications.
- Consistent texture eliminates air gaps when installed against flat or curved surfaces.
๐ Key Advantage: Provides a clean, industrial-grade finish for both functional and decorative sealing applications.
๐ง 12. Easy Machinability & Fabrication Flexibility
- Lightweight and flexible — can be cut, punched, slit, or trimmed with basic tools.
- Available with pressure-sensitive adhesive (PSA) backing for instant peel-and-stick installation.
- Can also be bonded with silicone adhesive, epoxy, or mechanical fasteners for permanent mounting.
๐ Key Advantage: Easy for on-site installation in workshops, factories, and project sites across Sabah, Sarawak, and Brunei.
๐ผ 13. Eco-Friendly & Non-Toxic Composition
- Free from CFCs, halogens, heavy metals, and toxic additives.
- Non-staining and safe for use in contact with painted or coated surfaces.
- Complies with RoHS and REACH environmental standards.
๐ Key Advantage: Sustainable material choice for environmentally responsible construction and manufacturing projects.
๐งฐ 14. Compatibility & Versatility
- Compatible with steel, aluminum, PVC, glass, polycarbonate, and painted surfaces.
- Does not corrode or react chemically with common substrates.
- Performs equally well under compression, bending, or shear forces.
๐ Key Advantage: Excellent for multi-material assembly and cross-industry applications.
๐งฑ 15. Custom Fabrication Options
- Custom extrusion available in rectangular, square, and irregular profiles.
- Available as continuous rolls, pre-cut lengths, or die-cut gasket shapes.
- Thickness range from 3mm up to 50mm, widths from 10mm up to 100mm.
๐ Key Advantage: Tailor-made to match specific sealing requirements or OEM standards.
