EPDM sealing strip | waterproof EPDM gasket | EPDM rubber sealing Sabah | EPDM foam Sarawak | rubber sponge strip Brunei

 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.

 Key Advantage: Maintains long-term watertight and airtight performance in high-humidity areas like Kota Kinabalu, Miri, Kuching, and Bandar Seri Begawan.

 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.

 Key Advantage: Delivers long-term outdoor service life for building facades, marine vessels, and automotive weather seals across coastal and inland towns.

 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.

 Key Advantage: Performs consistently across extreme environments — from cold storage insulation in Miri to roof seals under direct sunlight in Kuching.

 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.

 Key Advantage: Prevents permanent flattening, ensuring consistent sealing pressure over years of repeated use.

 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.

 Key Advantage: Guaranteed dimensional accuracy for OEM and industrial fitting applications.

 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.

 Key Advantage: Improves acoustic comfort and machinery stability in industrial facilities and vehicle interiors.

 7. Non-Conductive Electrical Insulation

• Volume resistivity exceeds 10¹ p 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.

 Key Advantage: Provides safe electrical isolation in high-voltage or electronics-related environments.

 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.

 Key Advantage: Ideal for chemical plants, laboratories, and maintenance areas across Bintulu, Sibu, and Seria.

 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.

 Key Advantage: Excellent for air-conditioning insulation, cold storage gaskets, and marine interiors.

 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.

 Key Advantage: Enhanced safety for high-risk or confined environments.

 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.

 Key Advantage: Provides a clean, industrial-grade finish for both functional and decorative sealing applications.

 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.

 Key Advantage: Easy for on-site installation in workshops, factories, and project sites across Sabah, Sarawak, and Brunei.

 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.

 Key Advantage: Sustainable material choice for environmentally responsible construction and manufacturing projects.

 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.

 Key Advantage: Excellent for multi-material assembly and cross-industry applications.

 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.

 Key Advantage: Tailor-made to match specific sealing requirements or OEM standards.

 16. Mechanical Properties Summary

 17. Long-Term Durability in Borneo’s Climate

• Withstands daily temperature cycling, UV intensity, and heavy rainfall common in Sabah, Sarawak, and Brunei coastal areas.
• Proven service life exceeding 10 years under normal outdoor conditions.

 Key Advantage: Reliable, long-lasting solution for infrastructure, marine, and industrial sealing applications across Borneo.
