Soft shot

TPEs are often employed to produce a resUient and soft ergonomic layer over a hard structural part. This could be done in a number of ways [213]. TPEs can also be overmolded onto an engineering material through insert molding or multiple-shot injection molding. 

PERLITE (or Pearlstone). An unusual form of siliceous lava composed of small spherules of about the size of bird shot or peas. It is grayish in color with a soft pearly luster. The spherules often show a concentric structure and are believed to be funned as a result of a peculiar spherical cracking developed while cooling. They may be confused with oolites, which are classified as concretions.

The philosophy of the use of shot cleaning is not so much to remove deposits but to prevent their formation. Indeed, if attempts are made to remove existing deposits by the use of shot it is possible for the deposit, particularly if it is molten or soft, to capture the shot and this could add to the fouling problem rather than alleviating it.
