PROMATECT® 250

PROMAXON® Mineral Board

PROMATECT® 250 comprises autoclaved calcium silicate spheres (PROMAXON® is a synthetic hydrated calcium silicate in spherical form) bound in a mineral matrix. PromaX® technology provides excellent fire performance in most applications.

PROMATECT® 250 is off-white in colour. One face is smooth and ready to form a finished surface, able to receive almost any form of architectural/finish treatment. The reverse face is sanded.

PROMATECT® 250 is resistant to the effects of moisture and will not physically deteriorate when used in damp or humid conditions. Performance characteristics are not degraded by age or moisture. However, PROMATECT® 250 is not designed for use in areas subject to continual damp or high temperatures. PROMATECT® 250 is for internal applications only.

Applications

  • Structural Steel
  • Ceilings & Floors

HEALTH & SAFETY

A health and safety data sheet is available from Promat and, as with any other material, should be read before working with the board.

 

WASTE DISPOSAL

The board is not classified as a dangerous substance so no special provisions are required regarding the transportation and the disposal of the product to landfill. They can be placed in on-site rubbish skips with other general building waste which should then be disposed by a registered contractor in the appropriate and approved manner.
