Title: FORMULATION OF MATERIAL FOR INSULATING WIRE AND PRODUCT PRODUCED THEREFROM
Abstract:
The invention falls within the field of insulating materials, specifically of compounds for insulating wire used in vehicles. The invention consists of a formulation comprising 10-50% by mass of a polyethylene or polyethylene copolymer base resin, 5-20% by mass of a Thermoplastic Elastomer base resin and 3-6% by mass of a primary antioxidant with fenol and metal deactivating properties. Said formulation allows a compound to be produced which has high heat resistance, chemical resistance and mechanical strength. In an improved configuration, said formulation further comprises 10-55% by mass of a mineral charge with fire-retardant properties, 1-3% by mass of a thioester-based antioxidant, 1-3% by mass of a phosphite-based antioxidant and 0.5-2% by mass of a phosphate-based antioxidant. Another subject matter of the present invention is a product produced by mixing said formulation and by subsequently cross-linking same.
