insulation properties and are non-combustible.
H91 & L21 have low thermal conductivity which
ensures consistent thermal performance.
Sindanyo® products have good compressive
and mechanical strength which is retained when
operating towards their maximum service
Both grades also have very good impact resistance
and toughness and can be easily cut, threaded and
machined to make intricate parts.
Other benefits include:
Resistant to most acids/alkalis
Easily threaded or tapped
Good wear resistance
High compressive strength
