1. Material Properties
– Base Material: Thermoplastic Polyurethane (TPU).
– Key Characteristics:
– High elasticity and flexibility.
– Excellent abrasion and tear resistance.
– UV-resistant and weatherproof (suitable for indoor/outdoor use).
– Slip-resistant surface (even when wet).
– Chemical resistance (oils, greases, mild acids).
– Shore Hardness: Typically Shore A 80–95 (varies by formulation).
– Temperature Tolerance: -40°C to +80°C (-40°F to +176°F).
2. Tactile Patterns & Dimensions
-Common Patterns:
– Truncated Domes(Warning tiles):
– Dome diameter: 23–35 mm.
– Dome height: 4–5 mm (per ADA/ISO standards).
– Spacing: 50–65 mm between dome centers.
– Directional Bars (Guidance tiles):
– Bar width: 30–40 mm.
– Bar spacing: 50–70 mm.
– Tile Sizes:
– Standard: 300×300 mm,.
– Thickness: 5–10 mm (depending on application).
3. Performance Data
– Load Capacity:
– Dynamic load: Up to 5,000 N (suitable for pedestrian and light vehicular traffic).
– Compressive strength: 15–25 MPa.
– Abrasion Resistance: ≤80 mm³ loss (tested via DIN 53516/Taber Abraser).
– Slip Resistance: Wet pendulum test (EN 13036-4) ≥36 (low slip risk).
– Fire Rating: Often Class B1 (DIN 4102) or equivalent (self-extinguishing).
4. Compliance Standards
– Accessibility:
– ADA (Americans with Disabilities Act) – U.S.
– EN 3011 (European Standard for tactile paving).
– ISO 23599 (International guidance).
– Local building codes (e.g., TGSI in Australia).
– Safety:
– Slip resistance: EN 16165 / AS 4586.
– Fire safety: EN 13501-1.
5. Installation & Maintenance
– Installation Methods:
– Adhesive-backed (for flat surfaces).
– Mechanical fixing (bolts or anchors for heavy traffic).
– Interlocking systems (modular designs).
– Surface Preparation: Clean, dry, and level substrate (concrete, asphalt, tile).
– Maintenance:
– Easy to clean with water/detergent.
– Resistant to mold, algae, and staining.
