Intellectual property & Disclaimer



The material used in SEAL'n TYPE is polyurethane (PU) which has been specially designed for KADOR to ensure excellent flexibility and long-lasting strength. Moreover, it has been formulated with additives to reduce discolouring (UV stability) and to promote anti-staticity. During the manufacturing process it is further de-staticised and an anti-glare finish is applied though it remains 'see-through' translucent. The material is lead and cadium toxin free. It is also re-cyclable.
SEAL'n TYPE (PU) complies with EC standards.

SEAL'n TYPE (PU) will stand up to abrasion, puncture, tear and impact, and resists many gasses, liquids and chemicals; both petroleum and water-based. In fact, it shows overall good chemical resistance. It will protect a keyboard from most common chemicals including many oils. At the very worst, it should give initial protection to keyboards where there is less chemical resistance and allow for timely removal before extensive damage occurs to the keyboard. For further information on PU Chemical Resistance and further detailed advice on specific applications of SEAL'n TYPE (PU), please contact KADOR's Technical Department.

SEAL'n TYPE (PU) also performs extremely well over a wide range of temperatures, remaining flexible from -73 degree C to well over 300 degrees C in certain conditions. The Specific Gravity of the material is 1.12. The Hardness Durometer is 85A. The Tensile Strength is 48 MPa. The Ultimate Elongation is 570%. The Ultimate Modulus at 100% Elongation is 6.8 MPa and at 300% Elongation is 12.1 MPa.


Cleaning SEAL'n TYPE (PU) can be undertaken whilst the cover is on the keyboard or if preferred, by removing, cleaning and replacing it. If the former method is used, please ensure that the computer is turned off or that the keyboard is unplugged. The cleaning process is best carried out with dilute soap or detergent solution. Proprietary cleaners should not be used unless specifically stated for cleaning purposes, as they may contain either an abrasive or solvent, both of which might adversely affect the PU. If in doubt, please check with : KADOR's Technical Department.
