Products: POLYPORE   A range of monofilament and fibrillated fibres for the rapid release of moisture when firing refractory castables and gunmixes. POLYPORE fibres are now widely used in the refractory market. POLYPORE speeds the removal of excess moisture during the initial firing phase. By creating microscopic capillary canals POLYPORE quickens the release of the free excess water, as vapour, out of the refractory, thereby minimising thermal stress damage and firing time. COST SAVINGS POLYPORE'S low cost and low dosage levels add, typically, less than 2% to the castable material cost but the payback in safeguarding against explosive failures, premature cracking and costly repairs can be immense. LOW DOSAGE LEVELS A dosage level of just 0.05 - 0.10% by weight is generally all that is necessary, i.e. 0.5 -1.0 kg of POLYPORE ST or MF per tonne of castable. Some refractory manufacturers however have found additional benefits at 0.2% by weight, i.e. 2 kgs of POLYPORE St or MF per tonne of castable.
