Polyurethane systems with excellent reaction to fire | Synthesia Technology

Polyurethane systems with an excellent reaction to fire are a totally safe insulation system for buildings, both structurally speaking and for the safety of their occupants. The different tests conducted on polyurethane's safety in case of fire dismantle the false myths surrounding this material.

Synthesia Technology is a manufacturer and distributor of polyurethane systems with several applications in the construction and industry sectors.

Hereafter, we present our spray applied polyurethane foam system with the best reaction to fire in the market, accredited by means of a test certificate  based on the EN 13501-1 standard "Classification according to the fire behavior of construction products and elements for buildings. Part 1: Classification from data obtained in reaction to fire tests ".

 

Poliuretan® Spray RF-351-C

Poliuretan Spray RF-351-C is a two-component polyurethane system containing HFC’s and formulated to obtain closed-cell rigid foams to be sprayedin-place for thermal insulation. It is applied by spraying with a high pressure equipment fitted with heating, with a mixing ration of 1:1 in volumen.

The main applications are the thermal insulation of building closings, houses (partitioning), industrial buildings, roofs, farms, ships, tanks, cool stores, etc.

Foam protection

Rigid PUR foams applied outdoors are darkened and brittle by the action of UV radiation. Thus, all foams that are to be used in these conditions must be protected with a suitable coating (acrylics, butyl rubber, vinyl, asphalt, mono and bi-component polyurethanes, etc.)

Synthesia Internacional, supplies an acrylic coating Acuthan AQ and urethane bi-components URESPRAY F-75.

The ideal coating is one which meets the following requirements:

  • Physical properties:
    • Resistance to atmospheric and chemical agents.
    • Good tensile strength.
    • Good foam adherence.
    • Resistance to UV radiation.
  • Regarding the application:
    • Fast drying.
    • Possibility of spray gun application.
    • Minimum thickness 0,5-1,0 mm.
