Haysite Grade 1000 laminate sheet is an outstanding material that is used in applications requiring exceptional weather and corrosion resistance. Grade H1000's unique polyester resin system provides corrosion resistance in sunlight and harsh weather environments in addition to meeting NEMA GPO-3 specifications for track resistance, flame retardance, heat resistance and physical properties. H1000 is particularly qualified for applications in the transportation industry due to its' low smoke generation, low smoke toxicity & halogen-free flame retardants. H1000 meets the rigid New York City Transit - Specification #64. Transit Authorities use Grade H1000 under their 3rd rail ties to provide electrical insulation, corrosion protection, UV resistance & most importantly to insure low smoke/flame toxicity in case of electrical failure. H1000, in a pultruded profile shape is used for electrical insulation for electrical cables, conduit & 3rd rail protection for workers.
