LD-6 Pyropel

Note: This is a variation of Pyropel (Rigid and Flexible 600ºF Polyimide Fiber Insulating Boards & Felts).

Pyropel industrial insulation comes in a wide range of thermal and mechanical properties to address specific application needs, from high compressive strength MD-60 for tool base or platen insulators to MD-18 for highly efficient perimeter insulation. Pyropel is also available in solid plastic form use as precision thermal/mechanical machine components.

Additional Information

Pyropel® is available in three different forms:

Low Density (LD)
A flexible form of Pyropel®, Pyropel LD is an industrial nonwoven. Typically used where thermal control is the major engineering concern, Pyropel LD can bcell nameasily wrapped around complex shapes or converted into insulation kits. Unlike other blanket type insulators, Pyropel LD is binder-free and has none of the shedding concerns of other common fiber-based materials
