Our polystyrene cutting machine is of both good exterior and great practicality with stable performance and reliable quality. It is available in a wide range of types and specifications. It has a good design, a simple structure, and fine workmanship.
A wide range of additives are also used. Catalysts (tin and amines) speed up the reaction, allowing large volume production runs. Blowing agents that form gas bubbles in the polymerizing mixture, are required to produce foam. The amount of blowing can be tailored by adjusting the level of water. Flexible foams are typically made using the carbon dioxide formed during the reaction of water with isocyanate. Rigid foams use hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HfCs), and pentanes as the blowing agents.

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.
