Polystyrene Thermal Insulation

Expanded polystyrene or EPS is a closed cell, resilient, lightweight, rigid cellular plastics material produced in a range of densities between 10kg/m3 and 35kg/m3. One of the main applications for products manufactured from EPS are thermal insulation systems such as pipe insulation. Expanded polystyrene is supplied as plastic beads in which an expanding agent, usually pentane, has been dissolve. In the presence of steam the thermoplastic polystyrene softens and the increasing vapour pressure of the expanding agent causes the beads to expand up to 50 times their original volume. During this stage the degree of expansion is controlled to achieve the desired density. Expanded polystyrene does not contain any ozone depleting substance and none is used in its manufacture.

Roxul Rockpipe Thermal Insulation

Roxul Stone Wool pipe insulation Type 650 are strong pipe sections, segments or lags fabricated from specially impregnated high quality Roxul Stone Wool. Applications for Roxul Stone Wool Type 650 pipe insulation include for industrial and process pipe work operating at temperatures up to 650 degrees Celsius making it ideally suited for application to high pressure steam lines, turbines, boilers and integral pipe work, control valves, steam heaters, turbine pumps etc. With the addition of an aluminium foil-facing, Type 650 pipe sections are designed for thermal and acoustic insulation of heating, ventilation and air-conditioning pipe work services operating in the temperature range 0-650 degrees Celsius (80 degrees Celsius limiting the outer foil temperature). The highly water repellent characteristics make Type...

Thermobreak Thermal Insulation

Thermobreak is a foil faced physically cross linked polyolefin foam insulation material containing flame retardant additives and is produced in a continuous web process. Thermobreak is based on PE homo and copolymers and foamed with an organic foaming agent by chemical decomposition. The two following gases are mainly produced: Nitrogen (N2) Carbon dioxide (CO2) Both are known as non-depleting substances to the ozone layer.
