Superwool® Plus™ offers the same benefits as the other members of the Superwool family but with improved handling strength & enhanced thermal properties. Superwool® Plus™ is manufactured from pure raw materials using a new manufacturing technology. In addition to enhanced thermal properties, large nuisance dust particles have been efffectively eliminated making the product soft to the touch and less irritating during use.
Superwool® Plus™ Blanket is made of long Superwool fibres having the same chemical formulation as the original and well proven Superwool 607® product. It is available in a wide range of thicknesses and densities. It exhibits outstanding insulating properties at elevated temperatures.
Superwool® Plus™ Blanket has excellent thermal satbil;ity and retains its original soft fibrous structure up to its maximu continuous use temperature. Superwool® Plus™ is needled from both nside and possesses high strength, before and after heating. Superwool® Plus™ Blanket contains neither binder nor lubricant and does not emit any fumes or smell during the first firing. Superwool® Plus™ is flexible, easy to cut and shape and easy to install.

1200°C/2192°F EN 1094-1
With Superwool® Plus™ fiber, the consistent use of pure raw materials in our factories globally has lead to the 1% shrinkage temperature rising from >1100°C to >1200°C. For this reason, the classification temperature is now given as 1200°C in line with the EN-1094-1 norm.
Superwool® Plus™ fibers have been proven over many years to withstand continuous use in an oxidizing atmosphere at 1000°C. This temperature is quoted as the Maximum Continuous Use temperature. For applications above 1000°C, Morgan Thermal Ceramics recommends Superwool® 607HT® fiber which has a classification temperature of 1300°C.
