Acrylic fibre flock is used in fire resistant paints for both safety reasons and improved coverage.
Under high temperatures the fibre expands into a foam like material without burning, this expanded foam bridges gaps and cracks that resist the spread of fire and also helps to prevent smoke transfer. PAN 60 is the grade used by major manufacturers in this application.
Other key applications for this versatile fibre are in the manufacture of friction pads and plates, roof and floor sealants and adhesives.
