The SDPferm RD 4221 Rigid Insulation Foam system is specially developed for isothermal in-situ injection for tanks and for the insulation of pipes carrying glycol water, crude oil, and district heating, fluid temperature: (-40\u00b0C \/ +100\u00b0C).<\/em><\/p>\n

The SDPferm system. RD 4221 is highly valued for<\/p>\n

    \n
  • An Iso-viscosity Polyol-Isocyanate<\/li>\n
  • Excellent adhesion to substrates (Stainless steel\/metal)<\/li>\n
  • An excellent lambda value<\/li>\n
  • Exceptional Dimensional Stability<\/li>\n
  • Excellent rigidity<\/li>\n<\/ul>\n

    The SDPferm RD 4221 Rigid Insulation Foam system is a two-component product designed for application via a mobile in-situ injection machine.<\/p>\n

    The Polyol is a composition based on Polyether and Polyester polyols, catalysts, and 100% reactive stabilizers, and latest-generation blowing agents (zero ODP and low GWP).<\/em><\/p>\n

    The Isocyanate is an MDI.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
