Moulding
Molding grade unsaturated polyester resin is specifically formulated for use in various molding processes where it serves as the primary matrix material. This type of resin is engineered to possess optimal viscosity and flow characteristics, ensuring it can fill intricate mold cavities completely and evenly
R'C POL 540S
SMC grade unsaturated polyester resin is a specialized material designed for Sheet Molding Compound (SMC) manufacturing processes. It serves as the matrix in SMC, binding together chopped glass fibers and other additives to make sheet moulding compound. This resin is formulated to exhibit excellent flow characteristics during molding, ensuring thorough impregnation of fibers and uniform distribution within the mold cavity. SMC grade unsaturated polyester resin undergoes rapid curing under heat and pressure, resulting in strong, lightweight composite components that offer exceptional mechanical properties, corrosion resistance, and dimensional stability. Its versatility makes it a preferred choice in industries requiring high-performance materials, such as automotive, aerospace, and electrical applications.
