To ensure you get the best results with your PU foam products, it's essential to follow the instructions carefully.

First, make sure to keep the temperature of the components constant at a minimum of 18ºC. This is crucial for obtaining comparable results.

When mixing the components, use a large mixer and set it to a speed of 1,500 rpm for batches of 5-10 kg. This will help prevent overdosing the foam in narrow cavities.

To prevent overdosing in narrow cavities, you may need to increase the amount of foam by up to 100%. This can help fill the cavity completely, but be aware that it may increase the density and pressure on the cavity walls.

Here are some general guidelines for mixing and applying the foam:

Manufacturing

Manufacturing polyurethane foam is a fascinating process. It's the reaction of two key chemicals, a polyol and an isocyanate with water, which combines with other ingredients and a blowing agent to create the foam.

The foaming process begins instantly, resulting in a bubbly froth that forms quickly. This is similar to bread rising, and it's a key part of creating the foam.

The froth hardens, forming a slabstock bun of polyurethane foam ready for fabrication. This process happens in a matter of minutes.

Flame retardant additives can be introduced during this manufacturing process to meet various fire code standards.

Instructions for Use

To ensure a successful project, it's essential to determine the required amount of PU foam accurately. This may involve an overdose of up to 100% in narrow cavities to completely fill the cavity.

The temperature of component A and B must be kept constant at a minimum of 18ºC. This is crucial for obtaining comparable results.

Before mixing, both components should be weighed or measured accurately. This step cannot be overstressed, as it directly affects the final product.

Mix component A and add component B to it. Use a large mixer, such as a large spiral mixer, and mix at a speed of 1,500 rpm for batches of 5-10 kg.

To help the foam adhere to the walls, wet the surface of small cavities using a brush, spray, or by tumbling the cavity. This simple step can make a big difference in the final result.

Place long, narrow shapes at an angle of 10-15º to fill them completely. This will ensure that the foam fills the cavity evenly and efficiently.

Make sure the temperature of the cavity is between 15-25ºC. This temperature range is ideal for the foam to set properly and achieve the desired consistency.

Empty
