Hand Mixing is an integral part of the polyurethane businesses. The aforementioned process is essential for Quality Control purposes or Research and Developments needs. It is a simple way to check for existing formulations or one that is being created. This ensures a systematic way of setting up a Hand Mixing area or Laboratory area. The necessary criteria includes:

• A mixer equipped with the necessary designed stirrer head
• A box for the foam to rise from
• Scales to weight the correct parts of chemicals necessary for the formulation.
• Proper extraction for the fumes (especially the isocyanates)
• A curing area, which could involve the facilitation of an oven.
• The different facilities necessary for the proper storage of chemicals, including equipment; as to ensure that no contamination is present which could affect the performance of the mix (or the formulation).
• The technique and initiative of making a so-called Hand-Mix (or a bun as it is referred in the industry).
