Mirror Shuttering Plywood Supplier Near Me 12mm 30kg, 8x4 ft

Product Details

Mirror Finish Shuttering Plywood – Technical Specifications & Performance Details 1. Material Composition & Manufacturing Standards - Manufactured in compliance with ISI/IS 4990 standards for phenolic film-faced shuttering plywood - Core constructed from high-density hardwood(typically eucalyptus) - Features boiling waterproof (PF grade) adhesive for complete water resistance - Film face options:   *Red Film: Minimum 120 GSM phenolic coating   *Black Film: Minimum 145 GSM phenolic coating (higher durability)   2. Structural Properties - Available in two thickness grades:   * 12mm (available in 30kg and 34kg weight variants)   * 18mm (available in 45kg and 50kg weight variants) - Density ranges from 850-1500 kg/m³ depending on thickness/weight combination - Bending strength: ≥30 N/mm² (exceeds IS 4990 requirements)   3. Performance Characteristics A. Reusability Cycles: Red Film Face:* - 12mm/30kg: 15+ pours (typical commercial construction) - 12mm/34kg: 20+ pours (heavy-duty applications) - 18mm/45kg: 15+ pours (standard formwork) - 18mm/50kg: 20+ pours (high-stress formwork)   Black Film Face (Enhanced Performance): - 12mm/30kg: 17+ pours - 12mm/34kg: 22+ pours - 18mm/45kg: 17+ pours - 18mm/50kg: 22+ pours   B. Surface Properties: - Surface roughness (Ra):0.8-1.2μm (mirror finish standard) - Concrete release performance: ≤0.15 N/mm² adhesion strength - Abrasion resistance: 2500+ cycles(Taber abrasion test)   4. Quality Assurance & Testing - Passes all IS 4990 required tests including:   * Boiling Water Test: 72 hours without delamination   * Moisture Content Test: Maintains ≤10% moisture content   * Glue Shear Strength Test: ≥1.5 N/mm²   * Formaldehyde Emission: E1 grade compliant (<0.5ppm)   5. Technical Advantages Over Standard Shuttering Plywood - 300% longer service life compared to conventional shuttering plywood - 50% reduction in surface preparation time between pours - 40% lower total cost of ownership per concrete pour - Maintains consistent surface quality throughout lifespan (no degradation in finish quality)   6. Recommended Applications - Architectural concrete(where surface finish is critical) - High-rise building cores(requiring multiple reuses) - Precast concrete elements (demanding dimensional accuracy) - Infrastructure projects (bridges, dams, tunnels requiring durable formwork)   7. Storage & Handling Guidelines - Store flat on leveled surface - Protect from direct sunlight exposure - Maintain dry conditions (relative humidity <65%) - Stack height should not exceed 1.5 meters   8. Economic Benefits - Cost per use analysis:   Standard plywood: ₹120-150/use (5-10 uses)   Mirror finish: ₹50-80/use (15-22 uses) - Labor savings: Reduces stripping/cleaning time by 40-50% - Material savings: Eliminates need for surface repair between uses   This plywood represents **the optimal choice** for contractors prioritizing: ✓ Maximum formwork reusability ✓ Flawless concrete finishes ✓ Long-term cost efficiency ✓ Consistent performance across multiple projects
