Since there is such a wide range of polyurethane chemistries, it is difficult to recycle foam materials using just one method. The majority of recycling involves reusing flexible slabstock foams for carpet backing. Over 100 million lb (45.4 million kg) of polyurethane carpet cushion is recycled every year into bonded carpet cushion. This involves shredding the scrap into flakes and bonding the flakes together to form sheets. Other methods have recently been developed. One method involves pulverizing the foam into granules, dispersing these granules in a polyol blend, and molding them into the same parts as the original. Ground polyurethane can also be added to original systems as a filler in amounts of up to 10%. Another method called press bonding bonds granulated scrap using an isocyanate-based binder into large boards with densities ranging from 400-900 kg/m3.
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.
The molecular structure, amount, and reaction temperature of each ingredient determine the characteristics and subsequent use of the foam. Therefore, each formulation must be designed with the proper ingredients to achieve the desired properties of the final material. For instance, a switch in blowing agent may require an increase in this additive to maintain thermal properties. Increasing the amount of blowing agent requires more water and a switch in surfactants to maintain optimum bubble sizes and formation rates during foaming. The density of the foam is determined by the amount of blowing. The stiffness and hardness of polyurethane can also be tailored by changing the level of flexible polyol in the chemical formulation. By mixing different combinations of the starting materials, the rates of the reactions and overall rate of cure during processing can be controlled.
