PIR INSULATION PRODUCT

Technical Specs

• Material: Polyisocyanurate (PIR), rigid closed-cell, CFC-free.
• Service Temperature: -170°C to +150°C.
• Standard: ASTM C591 Type II.
• Typical thermal conductivity (λ): approx. 0.022–0.026 W/m·K (depending on the mean test temperature).
• Linear dimensional stability at −30 °C (ASTM D2126): < 2 %.
• Water absorption (ASTM C272): < 2 % v/v -> low, the closed-cell structure helps limit moisture transmission and the risk of corrosion under insulation (CUI).
• Compressive strength: approx. 120–250 kPa (depending on orientation and material grade).
• Density & Compressive Strength: available in various ranges to meet different project requirements.

Applications

• Insulation for tanks, vessels, equipment, and pipelines.
• Refrigeration and cryogenic systems (LNG, oil & gas, refinery).
• Chilled water pipes and ducts, HVAC, refrigerated containers.
• Cold storage and food processing facilities.

Key Benefits

• Excellent dimensional stability across a wide temperature range.
• Low thermal conductivity → energy savings.
• Lightweight, easy to handle and install.
• High moisture resistance, prevents mold and corrosion.
• Compatible with a wide range of adhesives and coatings.

Key Features

• Superior thermal performance: reduces heat transfer and saves energy.

ROCK WOOL (STONE WOOL)

Key benefits for tanks

• Non-combustible mineral wool (EN 13501 A1); melting/burning point > 1,000 °C → strong passive fire protection.
• Moisture and Water Resistant, low water absorption (< 1 kg/m²) and low water-vapor sorption (≤ 1 %) → mitigates moisture-driven CUI.
• Chemically inert & durable; corrosion-tested per ASTM C795/C871 and C692; conforms to curved shells; compatible with aluminum/stainless
• Suitable for tanks/vessels up to 650 °C service temperature, ideal for Digester applications
• long lifetime of the insulation

Technical Spec

• Density (kg/m³): 80–175.
• Thickness (mm): 25–150 (use multilayer build-up when total thickness > 100 mm).
• Typical dimensions: Sheets 600 × 1200 mm; rolls 600 mm wide, 3–5 m long.
• Max service temperature: 650 °C; linear shrinkage ≤ 2 % at rating; ASTM E84: FSI = 0, SDI = 5.
• Thermal conductivity λ (W/m·K): 0.036 – 0.105, typical by mean temperature: 23 – 371 °C.
• Moisture performance: Water-repellent; water absorption < 1 kg/m²; water-vapour sorption ≤ 1 %.
• Fire & corrosion: Non-combustible A1, melting/burning point > 1,000 °C; CUI evaluated per ASTM C795/C871 and ASTM C692 (stainless steel).
