Product Description
Mix Ratio 1 / 1.5 ( 40 / 60 ) : Resin / Isocyanate [by weight].
Mix Ratio by Volume = 40 / 54 : Resin / Isocyanate.
ECOFIL 40 is a two component, all water blown, polyurethane
rigid foam system. At typical moulded densities of
40 to 50 Kg/m³, the Ecofil 40 system produces a fine celled foam
with low friability and good adhesion to substrates.
Approvals
ECOFIL 40 Buoyancy foams have been tested and evaluated for
use in life saving appliances according to the International
Convention For Safety At Sea “SOLAS” chapter III &
International Maritime Organisation ( IMO ). This certification was
issued by Lloyd’s Registered Shipping on behalf of the Maritime
Safety Agency ( MSA ) and Type Approval on behalf of the UK
Government Department of Transport ( DOT ).
IMO Resolution A 689 (17)
IMO Resolution MSC 81 (70) Part 1. (Copies available
on request).
Equipment
Process through suitable dispense machinery to produce
polyurethane foam for use in free rise, pour - in - place, or
moulding applications. The machine should be capable of
maintaining the mix ratio at ± 2% accuracy and temperature at
20-25ºC. Consult Isothane technical Staff for machine
manufacturer recommendations.
Component Description
ECOFIL 40 Resin component is a fully formulated liquid mixture. It should be stored in
sealed tanks or drums and heated to 20ºC prior to use. Viscosity @ 20ºC = 1000cps.
Specific Gravity @ 20ºC = 1.11.
ECOFIL 40 Iso is a liquid mixture containing crude Diphenyl – methane – diisocyanate. It
should be stored in sealed tanks or drums and heated to 20ºC prior to use. Viscosity @ 20ºC
= 325 cps. Specific Gravity @ 20ºC = 1.23.
Typical Properties
ECOFIL 40 when processed through suitable foam machinery gives a product of nominal
overall density: 40 to 50 Kg/m³.
