Beschreibung
Zusammenfassung:This invention falls within the scope of insulation materials, more specifically compounds aimed at insulating wires used in cars. It consists of a formulation comprising 10%-50% by mass of a polyethylene or polyethylene copolymers-based resin, 5%-20% by mass of a Thermoplastic Elastomer-based resin and 3%-6% by mass of a primary antioxidant with phenolic and metal deactivation properties. This formulation allows a compound to be obtained with high thermal, chemical and mechanical resistance. According to an improved configuration, it further comprises 10%-55% by mass of a mineral filler with flame 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. Additionally, a product which is obtained by mixing the said formulation and subsequent crosslinking is also the object of this invention.
