Print Treating
Where Corriboard is to be printed on or glued to, it is necessary to etch both surfaces during the extrusion process. Sheet is tested on line to a minimum dyne level of 52 dynes.
Conductive Corriboard
Supplied in black only. Surface resistivity 104 OHMS.
Anti-static Corriboard
Supplied in any grade or colour. Surface resistivity 1010 OHMS.
Flame Retardant Grade
Corriboard can be extruded with flame retardant additives to meet customer’s flame retardant requirements. e.g. The typical requirement for temporary protection sheets - LPCB Approved to LPS 12O7 - Fire Requirements For Protective Covering Materials. N.I.P. Certificate No. 341a. Other FR standards applicable.
Fabrication
Corriboard can be die cut, hot-air welded, ultra-sonically welded, glued and stapled.
Weathering
Corriboard requiring extended outdoor life must be UV stabilised. Assuming normal weather conditions for the UK, stabilised Corriboard will last from 5 to 7 years.
Filled Grades
Talc filled grades are available to enhance the performance of the sheet i.e. greater rigidity, surface smoothness and thermal stability.
