Dioctyl terephthalate is a type of plasticizer that is commonly used in the production of flame retardant, non-halogen and low smoke fire retardant tape. Calcined mica tape with double-sided fiber cloth is a type of electrical insulation tape that is made by combining calcined mica paper and fiber cloth with a binder. The tape is typically used for electrical insulation and fire protection in high voltage cables, transformers, and other electrical equipment. The combination of dioctyl terephthalate and calcined mica tape with double-sided fiber cloth provides high flame retardancy, non-halogen and low smoke properties, as well as excellent electrical insulation and mechanical strength.
