Plastics are, however, outgassing substances since they contain plasticizers that make them pliable and flexible. The plasticizers can evaporate from the plastic and condense on nearby surfaces, possibly affecting product processing. Rubber Items Rubber items can shed and should be contained in cleanroom packaging material. Also, certain solvents can attack rubber and break it down. Keep shelves and cabinets away from critical process areas to reduce the formation of vortexes.
Solvents Keep solvents in safety approved containers.
Cleaning and processing solvents should be filtered before use and should contain little or no soluble residue. Storage Containers Small containers with felt, foam, wood, or leather linings should be covered and sealed with cleanroom packaging material. Tapes Vinyl, nylon, and Teflon tapes are appropriate for cleanroom use. Tapes should not leave adhesive residues behind when pulled up. A cleanroom-dedicated tool set will eliminate the need for repeated cleaning to perform routine jobs.
