For flexible foam molding, dispensing machines are used to vary the output of chemicals or the component ratios during the pour. This allows the production of molded foams with dual hardness. Molded foam articles with solid surface skin are made from liquid chemicals in a single step, using carbon dioxide as the sole blowing agent. Automotive cushions are made by molding flexible foam behind a pre-shaped fabric cover. This process reduces the number of steps in the manufacture of car seats. In addition to monitoring the production process, the final product is inspected and tested for various physical and mechanical properties. An important property of foam rubber is called the indentation load deflection, which measures the spring tension or load-bearing quality of the material. The deflection is determined by the amount of weight needed to compress a circle of foam 50 sq in x 4 in (127 sq cm x 10.16 cm) thick by 25%. Most seat cushion foam has a rating of 35, which means it takes 35 lb (15.9 kg) of pressure to compress the circle of foam 1 in (2.54 cm).
PS Recycling machine is mainly used to recycle the high foam polystyrene and high foam polyethene products. PS Recycling machine is the ideal equipment to recycle waste materials. This PS Recycling machine features a compact structure and easy operation. The high foam plastic can be directly used to make granulation without comminuting. At present, the ps recycling machine from Haiyuan plastic recycling machine supplier is the ideal energy-saving equipment.
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. The two polyisocyanates most commonly used are diphenylethane diisocyanate (MDI) and toluene diisocyanate (TDI). Both are derived from readily available petrochemicals and are manufactured by well-established chemical processes. Though MDI is chemically more complex than TDI, this complexity allows its composition to be tailored for each specific application. MDI is generally used in rigid foams, whereas TDI is typically used for flexible foam applications. Blends of MDI and TDI are also used.
