Recycled sponge is a new product and a sponge treatment method used all over the world. Recycled sponge belongs to the recycling of industrial leftovers of polyurethane products. Its use value is no less than that of sponge. It is compressed and formed by crushed and stirred water vapor high-temperature disinfection, sterilization and deodorization.
It greatly reduces the production cost in terms of production cost and use. It has good elasticity, good durability, no deformation and no peculiar smell. It can be made into products of various densities according to customers' needs. It has the characteristics of high efficiency flame retardant, good tension, large elasticity and no deformation. After sterilization and odor removal by high-pressure steam, it is environmentally friendly, economical and practical.
In the renewable sponge processing system, the folk recycled sponge is absolutely not allowed to be used in the renewable sponge processing process, and the smell of the used sponge is very obvious. The smell of recycled sponge on the market is mostly due to the processing of used old sponge. Therefore, good recycled sponge consumers can rest assured to buy and use.
