Technical Content – Solid Rubber Dock Bumper
1. Material Composition & Properties
- Base Material: 100% industrial-grade vulcanized natural rubber (NR) blended with synthetic elastomers (SBR / BR).
- Hardness (Shore A): 65 ± 5 — provides balance between rigidity & shock absorption.
- Tensile Strength: ≥ 12 MPa — resists tearing under heavy truck impacts.
- Elongation at Break: ≥ 350% — ensures flexibility without cracking.
- Compression Set Resistance: Low permanent deformation after repeated compression cycles.
- Abrasion Resistance: ≤ 200 mm³ (DIN 53516) — suitable for high-frequency dock usage.
- Temperature Resistance: -30°C to +80°C (continuous service range).
- Weatherproofing: Formulated with anti-ozone & UV stabilizers for outdoor Borneo environments.
- Chemical Resistance: Stable against oils, diesel, mild acids, and seawater exposure.
2. Design & Construction
- Profile Type: Solid block design — no hollow cavities → ensures maximum durability under load.
- Surface Finish: Smooth front face with slight curvature to spread impact load.
- Reinforcement: Optional internal steel plate (custom orders) for heavy-duty marine docks.
- Mounting Holes: Pre-drilled holes (typically Ø16mm to Ø20mm) for anchor bolts.
- Color: Standard black (UV-stabilized). Optional reflective striping (yellow/white) for visibility at night.
3. Standard Sizes (Stock Models)
- Model 330: 100mm (Thickness) × 260mm (Height) × 330mm (Length)
- Model 450: 100mm (Thickness) × 260mm (Height) × 450mm (Length)
- Model 760: 100mm (Thickness) × 200mm (Height) × 760mm (Length)
- Model 300: 100mm (Thickness) × 300mm (Height) × 300mm (Length)
Custom sizing available for large marine berths, offshore rigs, or heavy-vehicle docks (up to 1200mm length).
4. Mechanical Performance
- Impact Absorption Capacity: Tested to withstand truck docking speeds of 2–5 km/h (standard reversing speeds).
- Load Capacity: Capable of absorbing impact forces from 10-ton to 40-ton trucks & trailers.
- Deflection under Load: ≤ 25% thickness compression at full impact.
- Rebound Resilience: 65% — ensures energy is absorbed, not transferred to structure.
5. Mounting & Fixing Technicals
- Recommended Fixing: Heavy-duty galvanized anchor bolts (M16–M20).
- Installation Surface: Concrete walls, steel dock frames, or marine jetty pillars.
- Bolt Depth: Minimum 75mm embedment into structural concrete.
- Installation Pattern:
- Model 330 & 450 → 2 mounting holes.
- Model 760 → 3 mounting holes.
- Model 300 → 2 or 4 mounting holes (depending on orientation).
- Mounting Orientation: Horizontal or vertical depending on dock design.
6. Performance in Borneo Climate
- High Rainfall Tolerance: Water-resistant rubber prevents swelling.
- UV Protection: Long service life under strong tropical sunlight in Sabah & Sarawak.
- Marine Environment Suitability: Saltwater-resistant → ideal for Kota Kinabalu Port, Sandakan Jetty, Bintulu Port, Muara Harbour, Kuala Belait Oil & Gas Base.
- Temperature Fluctuations: Performs reliably in both hot midday sun and cool night conditions.
7. Quality & Standards Compliance
- ISO 9001: Manufactured under certified quality management system.
- DIN 53505: Hardness test compliance.
- ASTM D2000: Rubber material classification.
- RoHS & REACH Compliant: Safe for industrial environments.
- Marine Grade Option: Meets PIANC guidelines for small vessel berths and docking.
8. Estimated Weight (Per Unit)
- Model 330 → ~6.5 kg
- Model 450 → ~9.0 kg
- Model 760 → ~13.5 kg
- Model 300 → ~8.5 kg
(Weights vary depending on density & custom reinforcement options)
9. Service Life Expectancy
- Normal warehouse use: 5–8 years.
- Heavy-duty port/marine use: 3–6 years (depending on impact frequency).
- With periodic inspection: Can extend beyond 10 years with minimal degradation.
10. Optional Upgrades
- Embedded steel plate for extra rigidity.
- Reflective safety strips for low-light visibility.
- Extra-thick profile (150mm–200mm) for container port applications.
