PURL-PIP42

APPLICATIONS FOR PURL-PIP42

• Versatile application → suitable for both hand-mixing and plural-component spray/pour equipment
• Controlled reaction profile → allows time for placement before full expansion
• High mechanical strength → delivers strong compressive and flexural performance
• Excellent flow characteristics → ensures uniform filling in complex or enclosed spaces
• Closed-cell structure → long-lasting thermal insulation and moisture resistance
• CFC-free and hydrocarbon/water blown → supports sustainable, low-impact manufacturing

Test results (ASTM C518, 23 °C):

• Thermal conductivity (k): 0.0249 and 0.0248 W/m·K
• Thermal resistance (R-value): 2.01 m²·K/W

Interpretation of the Values:

“PURL PIP42 was tested to ASTM C518 at 23 °C and achieved a very low thermal conductivity (k) of 0.02485  W/m·K. Lower k-values mean less heat transfer, so this result indicates excellent insulating performance. For context, high-performance rigid polyurethane/polyisocyanurate (PU/PIR) insulation commonly sits around 0.022 to 0.026 W/m·K (often quoted up to about 0.028 W/m·K depending on product and facings).

The measured thermal resistance was R = 2.01 m²·K/W (higher R means better insulation). R-value increases with thickness (R = thickness in metres ÷ k).

As an industry reference (ASTM C518 comparison data at 50 mm thickness), typical R-values are about 1.13 to 1.28 m²·K/W for EPS, ~1.39 m²·K/W for XPS, and ~1.92 to 2.00 m²·K/W for PIR/rigid PU. This places PURL PIP42’s R = 2.01 m²·K/W in the top tier of common insulation materials at a similar thickness”
