Wanzhao Chemical uses a unique process to prepare high-quality nano-montmorillonite, which can be added to rubber such as nitrile butadiene, styrene butadiene and ethylene propylene diene monomer, as well as engineering plastics such as polyurethane, polyolefin and nylon, which can greatly improve the crystallization speed of crystalline plastics and improve the mechanical properties, thermal properties and dimensional stability of polymer materials. The mineral can meet food-grade and pharmaceutical-grade requirements and meet higher environmental protection requirements.
