Can polypropylene outdoor seating be metallized for electromagnetic shielding?
Polypropylene outdoor seating can indeed be metallized to provide electromagnetic shielding (EMI protection). By applying conductive coatings such as nickel, copper, or silver through processes like electroplating or vacuum metallization, the plastic surface gains conductive properties. This modification allows the seating to block or redirect electromagnetic interference (EMI), making it suitable for environments requiring signal protection, such as military, medical, or tech facilities. However, durability and weather resistance must be considered, as repeated exposure to outdoor conditions may degrade the coating over time. Proper surface treatment and protective top layers can enhance longevity while maintaining EMI shielding effectiveness.
