The use of plastic media blasting was originally utilized by the military to replace toxic chemical strippers for the stripping of aircraft and aerospace components. Up until the early 1980’s, the most common method of paint removal was chemical stripping. Plastic media blasting offered major improvements in environmental and worker safety; provided significant operational savings; and quickly became a preferred method of paint and coatings removal. Blasting with plastic media provides operators with the ability to remove paint and coatings from aluminum and steel, without warping, marring or pitting surfaces; or damaging mechanical functions, bearings or seals. Plastic media leaves surfaces stripped smooth for new paint and coating applications. Hard abrasives such as sand, steel shot and aluminum oxide can damage surfaces, however, plastic blast media offers excellent solutions for efficient paint removal without damaging even delicate surfaces when using recommended blast parameters.
