demands on paper coatings have mushroomed in recent years
paper coatings now gets nearly 6M hits
on Google six times more than just 2 years ago!
Yet the single most important characteristic is still the
seemingly simple one of water vapour permeability.
Limited, world leader in water vapour permeability, has
launched the WVTR (Water Vapour Transmission) MK VI,
which represents a new generation of accuracy,
reliability and usability. Although the instrument is
technically complex, it is easy to use and produces
highly consistent and reproducible results. It can
measure the permeability of a paper coating to an
accuracy of a few parts per million (sometime to a few
parts per hundred million.
important as it determines the printability, paper
handling and a wide range of other physical
characteristics of both the paper and the coating, as
well as having a direct effect on its re-pulpability for
meter gives a series of digital readouts that can be
recorded or simply read off the LCD screen. It needs no
re-calibration and requires, at most, minimal training to
give results that are accurate to better than a few parts
per million (with some samples a few parts per hundred
million). Sensitivities are in the range 0.05
A wide range of variations is available, depending on the
specific application. Both single and multi-sample
systems and a variety of chambers are available for
testing samples the size of a thimble up to a pallet load
and beyond. A permeability measurement laboratory service
is also available from Versaperm.
