HS-2210SSK is an unsaturated polyester resin primarily made from isophthalic acid and standard diols, designed for injection/molding applications with BMC. It features high reactivity and excellent colorability. When used in combination with low-shrinkage additives such as HS-9817SSK and HS-9819, it can produce products with high surface quality, superior mechanical strength, and excellent electrical performance. It is suitable for applications such as electrical coil encapsulation and automotive components.
