Rock Wool Insulation — Fire protection

Description

1. Product Overview

This product is a high-density, non-combustible rock wool insulation engineered from premium basalt and slag, designed explicitly for passive fire protection and thermal/acoustic control in critical industrial infrastructure. Its primary industrial use lies in protecting high-temperature processing equipment, petrochemical facilities, power generation plants, and commercial building structural elements against fire spread and heat transfer. The key value proposition is its unique ability to withstand temperatures exceeding 1000°C without melting or releasing toxic fumes, ensuring asset integrity and regulatory compliance. Strategically, this product is indispensable for global B2B buyers seeking to mitigate catastrophic fire risk, reduce insurance liabilities, and meet increasingly stringent international fire safety codes (e.g., NFPA, EN, ASTM).

2. Key Specifications & Technical Characteristics

• Chemical Composition: Basalt (volcanic rock) >70%, metallurgical slag, and bio-soluble phenolic binder (binder content ≤4% by weight)

• Purity / Grade: Non-combustible Grade A (EU Class A1 / ASTM E136) — zero organic content degradation up to 750°C

• Physical Characteristics:

  • Form: Rigid boards, semi-rigid slabs, pipe sections, or loose-fill granules

  • Color: Dark brown to charcoal grey

  • Density Range: 80–200 kg/m³ (industrial fire-rated grades)

  • Thermal Conductivity: ≤0.038 W/m·K at 20°C

  • Melting Point: >1000°C (actual fiber fusion point)

• Packaging Options: Compressed stack packs with PE shrink-wrap, palletized for export; pipe sections in cartons with moisture barrier

• Shelf Life: Unlimited if stored dry indoors; recommended replacement after 10 years only if physically damaged

3. Core Industrial Applications

• Primary Industries: Petrochemical (refineries, LNG terminals), power generation (thermal, nuclear, biomass), marine & offshore (FPSO vessels, oil platforms), commercial high-rise construction, and industrial HVAC.

• Operational Use Cases:

  • Fire stops and compartmentation — sealing cable trays and pipe penetrations through A60/A0 rated bulkheads

  • Vessel and duct insulation — coating flare stacks, exhaust ducts, and oven walls

  • Structural steel protection — applying sacrificial board layers to delay heat-induced buckling

• Performance Advantages:

  • Fire: Zero flame spread; produces no smoke or dripping (unlike PU/PIR foam)

  • Thermal: Maintains low k-value at high temperatures; alternatives (glass wool) collapse above 300°C

  • Cost efficiency: Lower total ownership cost due to 50+ year service life; eliminates expensive sprayed-on cementitious coatings

  • Acoustic bonus: Reduces industrial noise by up to 30% (NRC 0.85–0.95)

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified with inline density scanning; every batch third-party tested for non-combustibility and compressive strength (≥40 kPa at 10% deformation).

• Supply reliability: Dual-source raw material contracts (EU‑sourced basalt + Asia-Pacific slag) ensure 99.5% on‑time delivery even during commodity shortages.

• Logistics capability: Compression packaging increases container fill density by 40% — reducing freight cost per usable m³.

• Price competitiveness: Direct-to-market pricing (no distributor markups) due to vertically integrated production, beating regional competitors by 12–18% on bulk tenders.

• Sustainability: 100% recyclable; manufactured with 25% post-industrial recycled slag; zero formaldehyde binder (bio‑soluble) exceeds EU REACH and US EPA TSCA requirements.

• Technical support: Dedicated project engineers provide CAD-ready installation drawings, fire certification documentation, and on‑site thermal modeling for compliance filing.

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 metric tons (20MT) — one full truckload or LCL consolidation

• Loading capacity per standard 20ft container: 18–20MT (depending on density and board thickness)

• Loading capacity per standard 40ft HC container: 22–24MT (volume‑limited for low‑density grades; weight‑limited for high‑density grades)
