The particles of thermosetting resins, opportunely angled and sharpened, are the ideal means for surface sandblasting avoiding removal of material from the part.
Uses and Advantages
The line of plastic abrasives, initially developed to remove paint from airplane fuselages, owing to its capacity of not causing any damages to the delicate aluminium substrate, is now used in a very wide range of applications, such as sandblasting of moulds for plastic materials and aluminium parts, deburring and sandblasting of composite materials, epoxy resins, polyester and glass fibres.
Cleaning moulds with conventional abrasives always tends to remove material, making surface rough and often altering critical dimensions. Sandblasting with plastic abrasive allows cleaning the mould without modifying the surface or changing the dimensions instead.
