MD-60 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:

Medium Density (MD)
Pyropel MD is a lightweight fiberboard with superior insulation properties. Pyropel MD-12, MD-18, and MD-30 are semi-rigid and are normally used in areas that require both isolation and limited mechanical resistance.
Pyropel MD-50 and MD-60 are rigid insulation for mechanically demanding areas. More resilient, MD-50 is ideal when loading is not evenly distributed or when equipment alignment is not perfect. MD-60 is the most structurally rigid grade of Pyropel MD and offers the highest compression resistance and physical tolerances.
