urethane for wood structural members

Item: Spray Polyurethane Foam--wanefoam 904

Kind: Open Cell Polyurethane

Application: Building wall insulation, internal insulation, wall insulation sandwich, plant color steel roof insulation, Wood Roofs Insulation , Wood Wall Insulation, Wood construction insulation Bathtub insulation, and other areas of low density water spray combination of materials.

Foaming Agent : Water ( free of HCFC-141B and free of HFC System foaming agent)

Density : 8kg/m3

Each ton raw material can get 38 cubic memtes Foam!

No worry for customs about 141b or HFC foaming agent!

Specification:

Free Foaming Parameters:

Advantage are as follows:

a)Outstanding thermal insulation properties:

Hard polyurethane foam’s heat conductivity coefficient is one of the lowest among the building thermal insulation materials in current market.

b) Integration of the function of waterproof and insulation:

The percentage of close area of Wanhua hard polyurethane foam exceeds 90%; the percentage of water absorption is extremely low.

c) Outstanding fire resistance:

The polyurethane material can achieve the architectural design requirements after the flame retardant treatment.

d) Wide range of application:

Long-term applicable temperature is from -50 °C -150 °C, which can reach 250 °C in short-term.

e) Excellent weather resistance:

Which can be normally used for 30 years under the condition of 130c, whose lifetime is more than 70 years under the condition of 50c.

f) High strength:

High deformation of flexibility, high ability of Resistance of deformation, which will not easily crack even under the adverse effects of external force, temperature, humidity, and effectively keep the stability and durability.

g) Excellent self-adhesion:

Which can be bonding directly with cement, steels, clay, bitumen, woods, glass, plastic, the adhesive strength is much greater than its own cracking resistance.

h) Sound insulation:

Excellent sound insulation could provide the comfortable and quiet indoor environment.

I) Energy Saving, Environmental protection:

No Freon, No Benzene, Green & pollution-free, it can fully comply with environmental requirements.

FAQS:

1. How Polyurethane Foam Is Formed?

Polyurethane Spray Foam Insulation is formed when two chemicals (Diisocyanate and Polyol) are mixed together in the presence of suitable catalyst and activators. In spray foams, this takes place in the small mixing chambers of the hand-held spray gun. The gun is fed by hoses from metering pumps placed in each component drum chemicals. On mixing, the reaction gives off heat which is used to vaporize a refrigerant blowing agent which causes the mix to expand to a foam some 30 times the volume of the liquid constituents. Thus, the normal density of the foam is in the range of 30 to 38 kg/m3, and by virtue of the low thermal conductivity of the gas entrapped within the foam cells, provides excellent insulation value.

2. What we should do for the surface preparation?

Removal of loose particles (paints & rust).

Free from oil, water, dust & grease.

3. Polyurethane Insulation Application

Polyurethane insulation is sprayed directly to the surface of roof or to any substrate.

One (1") inch thick is the minimum required thickness of the foam.

Appearance of the foam is most likely orange peel to tree bark (depends on wind shear)
