Jlab Export is a leading PU Foam Manufacturer,and suppliers in India

PU foam is polyurethane that leaves the can as a bead, expands to fill the gap and sets into a firm foam. In refrigeration and air conditioning work it seals the wall hole around split AC pipes and fills gaps in insulated panels. The foam is white, each can holds 750 g, and every can comes with its own dispensing gun.

Practicals: Sealing Pipe Holes and Panels

In a split AC installation practical, students drill the wall sleeve hole with a Rotary Hammer Drill. The copper lines are sleeved in Copper Pipe Insulation and passed through the hole. Students mist the hole lightly with water, fill it part way with foam and let it expand around the pipes. Once cured, the foam is trimmed flush and the hole is finished with a Wall Cover.

For a cold room or refrigerator cabinet repair, teachers show how a gap in a panel joint lets heat and moisture in, and students fill and trim it. Shaking the can well, holding it upside down and working in short passes give an even bead.

Frequently Asked Questions

How long does the foam take to set?
It forms a skin first and then cures through. The time depends on temperature, humidity and bead size, so wait until it is firm all the way through before trimming. A light water mist on the surfaces helps it cure.

How much of the gap should be filled?
Fill only about a third to a half of the depth, because the foam keeps expanding after it leaves the can. Overfilling pushes foam out of the gap and can bend thin frames or panels.

Can cured foam be cut and painted?
Yes. Trim it flush with a sharp knife once it has cured through. Cured PU foam yellows and crumbles in sunlight, so foam on an outside wall is covered with a wall cover, a sealant or a coat of paint.

Does the foam insulate as well as seal?
Yes. Cured foam is full of small gas-filled cells that slow heat flow and stop draughts. That is why it is used around pipe holes and panel joints, but it does not replace the insulation sleeve on the copper lines.

What safety steps apply?
Wear gloves and eye protection, since wet foam sticks to skin and is hard to remove. Work with good ventilation and keep the can away from heat and flames.
