OPIPL CFC free rigid closed cell PIR foam is manufactured in similar way to standard Polyurethane which has all the characteristics and advantages of rigid Polyurethane foam but offers greatly increased resistance to burning and spread of flame and is able to withstand temperatures up to 140°C. When subjected to fire the outer surface of the foam forms a strong carbonaceous layer, which retards further flame spread and penetration.
OPIPL CFC free rigid closed cell PIR foam has a low Thermal Conductivity of less than 0.023 W/m °C at 10 °C, gives excellent thermal properties and fire properties when tested in accordance with ASTM E84. With 95% closed cell content, low thermal conductivity values, high compressive strength, durability and dimensional stability. we can achieve optimal energy savings and provide long end satisfactory service life.
For Pipe Size over 24" we recommend PIR Sheets for Pipe Line insulation.
We manufacture bends of 90 degrees which helps in saving labour on site while installation.
