MICROTHERM HYDROPHOBIC BLOCK
Waterproof high temperature insulation 
 
Properties 
Microtherm® Hydrophobic Block is the water resistant grade of Microtherm® Block, selected for applications where exposure to water in liquid form may cause damage to the insulation structure. Microporous insulations have around 90% structural voidage and will readily absorb water. This water can cause a partial collapse of the insulation structure with an associated increase in thermal conductivity. Hydrophobic Microtherm® can actually be immersed in water for long periods without any harmful effects. It may absorb up to 10% by weight of water into its void structure but it can then be dried off by simply allowing the water to be drained and released from the insulation. This will cause no degradation of the excellent thermal protection capabilities of the Microtherm® insulation. 
 
Key benefits 
Microtherm® Hydrophobic Block. * Water repellent microporous insulation offering the lowest theoretically possible thermal conductivity over a wide temperature range up to 1000 °C (1832 °F) * Available from stock in a range of thicknesses for maximum versatility in use * Environmentally friendly with no known health hazards when used within prescribed temperature limits. 
 
Your value 
Microtherm® Hydrophobic Block * Fully water resistant up to 250 °C (482 °F). This is progessively destroyed at higher temperatures * Microtherm® thermal insulation has a thermal performance at least 3 to 4 times better than conventional insulation materials at high temperatures. It has a thermal conductivity even lower than still air * Microtherm® insulation solutions occupy much less volume than conventional insulation materials and offer weight savings * • Available in a range of stock thicknesses, and also in tailor made sizes for simplest and fastest installation in specific applications.
