    VANCOUVER, Wash.—Emerald Kalama Chemical has expanded the range of chemistries in its portfolio of plasticizers with Vitroflex B, designed for performance with environmentally friendly polysulfide sealants.

    The product is a non-phthalate plasticizer optimized to enhance performance characteristics in the catalyst side of two-component polysulfide sealants, according to a company release.

    Conventional plasticizers used in polysulfide sealant applications such as benzyl phthalates and certain chlorinated paraffins are increasingly subject to regulatory pressure and restrictions, said Emerald. Vitroflex B is expected to be a more environmentally friendly alternative to chlorinated paraffins, as well as Registration, Evaluation, Authorization and Restriction of Chemicals-compliant.

    Emerald said Vitroflex B also enhances performance characteristics, achieving faster hardness development, improved lap shear strength and flexibility, adhesion and elongation. It is non-settling because of high viscosity stabilization and provides compatibility for formulation stability over time.

    Polymeric chemistry represents a significant growth opportunity for Emerald, said Julie Vaughn, global business development director. The technology will serve as a springboard to new applications such as vinyl, adhesives, sealants, coatings and films.

    Emerald is a producer of benzoic acid, benzaldehyde and related chemistries, as well as a producer of antioxidants and accelerators.
