A Safe Place: Storage Strategies for Plastics (Article)

16/10/· Plastics can be degraded by many factors, including light, ultraviolet radiation, oxygen, water, heat, and pollutants. The pollutants can come from the atmosphere, sticky fingers, or storage and packaging materials that outgas acids. 1 Since many plastics collections spend most of their existence in storage rather than in exhibition, an effective conservation strategy can be based on slowing Puhui Pipe manufacturer in China
