RRIM-PU

Reinforced reaction injection molding polyurethane (RRIM) is another rapidly developing new material after reaction injection molding polyurethane (RIM). RRIM polyurethane is the addition of reinforcing fillers to RIM polyurethane to improve various properties, which can meet the needs of the automotive industry And other industries have high performance requirements for materials. RRIM polyurethane is characterized by large modulus, good heat resistance, and small expansion coefficient. It has better performance than RIM polyurethane and is particularly suitable for automotive exterior materials. Therefore, although it is only six years old Development process (calculated since the advent of the first RRIM polyurethane molding machine), RRIM polyurethane products
