Raw Material Formula Solution Support:

We have our own technical team of chemical engineers and process engineers, all of whom have more than 20 years of experience in PU industry. We can independently develop raw material formulas like polyurethane rigid foam, PU flexible foam, polyurethane integral skin foam and polyurea that meet all customer’ s requirements. Application: The use of anti-noise earplugs made of polyurethane sponge has many advantages. First of all, because of its good slow rebound characteristics, it can better fit people’s ear canals and have an effective noise reduction effect. Second, compared to silicone, earplugs made of polyurethane sponge have better softness and air permeability, and higher wearing comfort, suitable for sleeping earplugs and long-term use. Third, the polyurethane sponge is safer to use, it is harmless in direct contact with the human body and has little hidden danger.    Our Factory: Yongjia Polyurethane Co., Ltd. is a professional machinery manufacturer in PU industry combined with design, development, production.
