AF COLLAR C
Special Fireproofing collars for plastic pipes
AF COLLAR C is an innovative and patented fireproofing collar that enables to seal the passages of plastic pipes. Its particular "C" shape makes its application suitable on pipes with curves adjacent to floors and walls.
AF COLLAR C are made of stainless steel and highly intumescent material. In case of fire, the pipe suffers a deformation and melts gradually until its complete combustion. Meanwhile, AF Collar C’s intumescent material spreads and creates a barrier able to grant thermal insulation and to maintain intact the wall/floor for at least 180 minutes.
