• Monitor
![Page 22: Care of Plastics In Art & Design collections derek.pullen@tate.org.uk 07974985849 derek.pullen@tate.org.uk.](https://reader035.fdocuments.in/reader035/viewer/2022070323/56649d9e5503460f94a89139/html5/thumbnails/22.jpg)
Signs of Deterioration• Odour – acidic, camphor (CN)• Change: colour -yellowing, bleaching
shape –distortion, sagging, sweating – oily spots
bloom – white powdercracks, splits (CAc) and crazing(CN)
• Corrosion of metal parts• Discolouration of packing materials• Increased brittleness, crumbling of foam• Onset is unpredictable and rapid• Occurs at stress points and handled areas• Unstable environments cause stress

• Affects both the plastic and pigments
• Control light in storage and on display
• UV component in light is most damaging
• Use UV filters on windows and lights

Storage – Problem Plastics
• Isolate and separate ‘at risk’ from ‘deteriorating’ objects
• Use:– Acid free paper– Silicone release paper– Polyester wadding– Ventilated polypropylene containers
• Scavengers for acidic gases– Charcoal cloth and zeolites– Artsorb board

Storage – Problem Plastics
• Check vulnerable ‘at risk’ items at least once a year, preferably more often.
• Use smell and dampened indicator strip to confirm acidic off-gassing.

Display –Problem Plastics
• Low light - less than 100 lux
• Ventilated plinth covers
• Allow at least 72 hours for plinth paint to dry before covering
![Page 38: Care of Plastics In Art & Design collections derek.pullen@tate.org.uk 07974985849 derek.pullen@tate.org.uk.](https://reader035.fdocuments.in/reader035/viewer/2022070323/56649d9e5503460f94a89139/html5/thumbnails/38.jpg)
Labelling
• Avoid solvent based inks, paints and isolating layers.
• Avoid adhesive tapes
• Avoid rubber bands
• Use tie on labels with cotton tape
• Use soft pencil (inside objects)
![Page 39: Care of Plastics In Art & Design collections derek.pullen@tate.org.uk 07974985849 derek.pullen@tate.org.uk.](https://reader035.fdocuments.in/reader035/viewer/2022070323/56649d9e5503460f94a89139/html5/thumbnails/39.jpg)
Cleaning• To remove dust and contaminants• Cleaning causes damage – both mechanical and
chemical• Decide on a balance between appearance and
risk of damage • Avoid solvents, eg alcohols, acetone, cellulose
thinners, cleaning fluids• Use soft dry lint free cloths, eg microfibre • For stubborn marks only, use water to dampen
cloth and dry immediately

Other plastic formats
• Fabrics – costumes and accessories - provide supports, isolate PVC’s
• Photograhic – archival quality storage materials
• New media: videos, tapes, disks – a management policy is essential for maintenance and migration.
