What is the difference between the different styles of PTC of durometers ?
The choice of style depends on both the application and personal preference. The most popular style for general use is the ‘classic’ which features a large stable base which is great for general use as well as printing rollers. The ‘ergo’ style features a medium base ( 1×1 inch) and a wine glass shaped body which allows access to smaller areas than a ‘classic’. The ‘e2000 ‘ is the choice for stability in a Digital or Analog Durometer with a 1.25″ base. Finally there is a ‘pencil’ style which features the minimum size base ( 1/2 inch diameter) allowed by the ASTM D2240 standard and although not as stable as a ‘standard’ or ‘ergo’ it allows access to the more restricted areas.
