Abstract:
There is provided an insulation foam in a tubular form, comprising at least one seamless layer of crosslinked polyethylene (PEX) closed-cell physical foam. The tubular foam can favourably be used to thermally insulate tubes that convey water, refrigerants or other fluids, in particular, copper tubes for Heating, Ventilation, Air-Conditioning and Refrigeration (HVAC&R) applications, as well as plastic tubes for use in domestic plumbing systems, hydronic radiant heating and cooling systems. There is also provided a method for manufacturing a crosslinked polyethylene (PEX) closed-cell physical foam in seamless tubular form, an insulation foam material using the same and a polymer blend for its manufacturing.

Claim (Index 18):
A polymer blend, comprising\n a polyethylene base resin comprised of 75.0 to 95.0 wt. % of at least one of LLDPE LDPE, or HDPE; a crosslinking agent comprised of 0.75 to 4.0 wt. % of at least one of silane cross-linker or trimethoxyvinylsilane; a crosslinking catalyst comprised of 0.1 to 2.0 wt. % of at least one of organometallic tin compound or dibutyltin dilaurate; a grafting aid for crosslinking agent comprising at least one of organic peroxide or dicumylperoxide; an antioxidant comprised of 0.5 to 3.0 wt. % of at least one of hindered phenolic, phosphite, amine and silane-derived antioxidants, or a methyldecyipolysiloxane-based compound; a cell regulator comprised of 0.75 to 3.0 wt. % of at least one of talo, clay, silica gel; a cell regulator additive comprised of 0.01 to 1.0 wt. % of at least one of stearate salts or zinc stearate; an antistatic agent comprised of 0.01 to 1.0 wt. % of cocamide diethanolamine; a cell stabilizer comprised of 0.01 to 1.0 wt. % of at least one of glycerol ester and amide compounds, stearamide-related compounds, or glycerol monostearate; a call stabiliser additive comprised of 0.01 to 1.0 wt. % of waxes or Montan wax; a color agent comprised of 0.01 to 0.10 wt. %; and a fire-retardant additive; and one or more additives.
