Fesch Polyurethane Foam

How to use Fesch Polyurethane Foam

The pipette or gun apparatus is screwed to the valve on the tin. The can is shaken vigorously for 20 seconds and pressure is applied to the trigger of the straw or gun, holding it upside down. The stronger the pressure, the stronger the output. On vertical surfaces, the foam is always applied from the bottom up. During the application, care should be taken to ensure that the ambient and tin temperature is within the range specified in the product TDS.

What is Polyurethane Foam?

Polyurethane foam is a one-component, semi-rigid assembly, joint filler and insulation material in aerosol form that cures with humidity in the air, expands while curing.

Flexible Polyurethane Foams are mainly used in door and window assembly, all kinds of gap filling applications, sound and heat insulation, waterproof barriers and insulation against fire. After polyurethane foam is applied, it reacts quickly with the moisture in the air and expands. Thanks to the superior bonding strength of polyurethane, it adheres strongly to the surfaces it is applied to.

What are the Uses of Polyurethane Foams?
Door and window assembly is the most effective use of PU Foams. Insulation of electrical installations, hot and cold water pipes, bonding of roof tiles, for sealing purposes on terraces, curtain concrete of buildings, industrial roof insulation, cold storages and icehouses, on the deck of ships and yachts, filling the gaps between exterior insulation materials, adhering insulation materials It is used for space filling and isolation in dry food warehouses.

What are the Polyurethane Foam Types?
Polyurethane foams can be divided into two parts according to the application type and purpose;

Polyurethane Foams According to Application Type;
Foams with Straw: It can be said that it is the most common and best-selling foam type in the market. It is applied with the pipette apparatus supplied with each can. It is preferred for filling relatively large gaps due to its high expansion rate (200%-250% on average). Fesch PU Foam is preferred in pipette foam applications.

Polyurethane Foams According to the Purpose of Use;
Cavity Filling Foams: It is the standard and most used foam type.
Adhesive Foams: They are foams with increased adhesive properties because their expansion rates are much lower (minimal) than standard foams and their polymer is more dense. With these products, heat insulation materials such as EPX, XPS, various construction elements such as gas concrete, brick and marble can be adhered.

Contribution of Polyurethane Foams to Sound, Heat and Water Insulation;
  Correct application of PU Foam is required for a good insulation.

Sound insulation

They are used in filling the gaps between the materials used for sound insulation, in order to prevent the passage of sound, heat and air in the door and window gaps, insulating the environment of ventilation pipes, chimneys and climatic units extending outside the buildings, and in many other similar areas.

Thermal insulation
For thermal insulation, 2-component rigid (rigid) foams are preferred.

Water isolation
Water cannot harm a properly applied and fully cured foam. Single-component polyurethane foams are preferred in outdoor applications, ornamental pools, attaching decorative stones to each other, in caravan type vehicles to prevent water leaking from the joints of mechanisms such as the climatic unit or antenna. Fesch provides a long-lasting and effective solution in sound, heat and water insulation applications.
