• Product 2 Components consisting of a Component A mixture of Polyols, catalysts, stabilizers, flame retardants and expanding agents and a component B consisting of Diphenylmethane-Diisocyanate (MDI).
• Does not contain CFCs, HCFCs or HFCs that affect the ozone layer.
• No adhesives needed: Good adhesion to the substrate where it is applied.
• The pieces obtained with this system have a regular distribution of density throughout the entire element and present great rigidity, as well as preserving their insulation characteristics.
• Product for injection applications.

It is applied by injection with high and low pressure machines. To foam a hollow body, the volume of said body to be foamed will be calculated and multiplying this value by the final density of the foam that you want to obtain, you will have the necessary weight of material that will have to be injected into the piece, according to the following relationship.
WEIGHT = VOLUME To do this, it is necessary to take into account the flow rate of the machine and the creaming time of the material, so that:
INJECTION TIME < CREAM TIME
INJECTION TIME = WEIGHT / FLOW
It is necessary to use a counter mold that supports the expansion force of the material against the walls of the body. This pressure, in addition to other factors, depends on the following relationship:
FINAL DENSITY / FREE DENSITY = DEGREE OF DENSIFICATION
Generally the system uses a degree of densification between 1.3 and 1.8
(final density: 40-60 Kg/m3). In this range, the pressure exerted by the foam can vary between 1-1.5 Kp/cm2.
When the foam cannot develop properly, due to the body walls, or is forced to follow a certain position, an increase in density occurs.
This is because the heat of reaction is dissipated and friction forces are produced.
The loss of heat of reaction can be largely avoided by previously heating the molds to 40-45 ºC. Furthermore, at low temperatures the adhesion of the foam to the substrate decreases.
The effect of friction, produced by the walls of the body, is all the more important the larger the surface is in comparison to its volume.
Likewise, the flow path that the foam must travel when filling the pieces has an influence on the final density. The injection point should preferably be located so that the flow path to be followed by the reaction mixture is as short as possible.
The exact amount of material to fill a body is normally determined when
This is in a complicated way, through some previous tests.
The demolding time, the time in which the part can be removed from the mold, depends mainly on the foam thickness and the dimensions of said part.
Component A needs prior preparation. Components A B do not need preparation prior to the process.

Once component A has been conditioned, mix with component B, with a mixing ratio of 100/100 parts by volume, according to the Table below:

Cream time (1) 14 ± 3 seconds
Thread time (2) 100 ± 10 seconds
Rise time (3) 135 ± 20 seconds
Touch time (4) 175 ± 25 seconds
Free glass density (5) 60 ± 2 g/L

(1) Creaming time: Time in which a sudden increase in the viscosity of the mixture occurs from the beginning of stirring. It is determined by visual appreciation and coincides with the beginning of expansion.
(2) Thread time: Time it takes for the mixture to form a thread from the start of stirring. It is determined by visual appreciation and coincides with the moment in which, by repeatedly inserting and removing a thin rod inside the foam, the first thread appears.
(3) Rise time: Time it takes for the mixture to expand after stirring. It is determined by visual appreciation and coincides with the end of the expansion.
(4) Touch time: Time it takes for the mixture to dry. It is determined by the touch of the foam and coincides with the moment in which we do not drag the foam.
(5) Glass free density: Quotient between the weight of the foam contained in a glass and its volume.
The expansion of the foam is carried out through the action of carbon dioxide (CO2) from the chemical reaction of water with Isocyanate.

To clean materials and utensils, use FUTURSOLVENT 001 before the product hardens. Once the product has hardened it can only be removed by mechanical means.
Storage: Components A and B are sensitive to humidity, and should always be stored in hermetically closed drums or tanks. The absorption of water by component A can cause processing failures. On the other hand, component B reacts with humidity forming insoluble polyureas and releasing
CO2.
The storage temperature must be between +10 and +25º C. Temperatures outside this range must be avoided, as they can cause crystallization of component B at low temperatures (at -10ºC component B crystallizes, causing clogging of the machine pipes), as well as altering the composition of component A at higher temperatures. Likewise, direct exposure of the drums to the sun should be avoided.
Never leave the Component A (polyol) container open.
If the drums are stored properly, the shelf life is 3 months for component A and 6 months for component B.

• The foam obtained with this system is characterized by having a regular distribution of density throughout the entire element and presenting great rigidity, as well as preserving its insulation characteristics through the injection technique.
