What is Slabstock foam?

What is Slabstock foam?

Slabstock polyurethane foam is the heart and soul of comfort in many consumer products. Comprehensive range of standard polyurethane raw materials (TDI, MDI and polyether polyols) supplied from our North American plants. Differentiated isocyanate blends and polyols grades, including graft polyols.

What are the chemicals used to make foam?

Most foams consist of the following chemicals: 50% polyol, 40% polyisocyanates, and 10% water and other chemicals. Polyisocyanates and polyols are liquid polymers that, when combined with water, produce an exothermic (heat generating) reaction forming the polyurethane.

What is flexible slabstock?

Checking the box below signifies your acceptance of these Terms and Conditions, which apply to all purchases. You must accept before you can continue. true. Polyurethane Manufacturing. Flexible Slabstock Foam.

What is flexible slabstock polyol?

Flexible Slabstock Polyol is a polyether and on reaction with catalysts and additives, yields polyurethane foams used in upholstery, mattresses, pillows, boosters, transport seating and packaging.

How do you manufacture PU foam?

The process for production of Polyurethane Foam (PUF) includes production and testing of Base Polyols (Grade PD & AM) and subsequent formulation with catalyst and surfactants. The isocyanate component mixed alongwith the formulated polyester polyols is used for production of Rigid Polyurethane Foam.

What is foaming machine?

Automatic Batch Foaming Machines are designed to produce flexible PU foam. The typical construction of machine includes tanks, molds, and counters and is run by electrical motor. The machine is designed to produce PU foam of different thickness and quality.

How is isocyanate made?

Isocyanates are usually produced from amines by phosgenation, i.e. treating with phosgene: RNH2 + COCl2 → RNCO + 2 HCl. These reactions proceed via the intermediacy of a carbamoyl chloride (RNHC(O)Cl). Owing to the hazardous nature of phosgene, the production of isocyanates requires special precautions.

How is polymer foam made?

Polymer foams are produced in a number of different ways. Examples are through slab-stock by pouring, extrusion and different forms of molding. Polymer foams can be divided into either thermoplastics or thermosets, which are further divided into rigid or flexible foams.

What is polyether polyol?

Polyether polyols are key components used in the production of polyurethanes. Polyether-based polyurethanes exhibit enhanced hydrolytic stability and excellent resistance to weak acids and bases compared to polyester-based polyurethanes.

What is the chemical formula for polyurethane?

Chemical Properties

What is polyurethane foam machine?

Polyurethane Spray Foam machines, also commonly referred to as proportioners, are highly sophisticated pieces of spray foam equipment. Polyurethane spray foam machines separate two fast reacting spray foam components and then dispense the mixed chemicals in the proper ratio.
