Utilizing its proprietary technology, the Speciality Chemicals division mainly produces high-performance resins to meet a variety of market needs in many fields such as electronics, information recording materials, automotive industry, and industrial materials. It offers a variety of
products to meet its customers’ needs.

Polyvinyl acetal resin which consists primarily of polyvinyl butyral resin (PVB) produced using Sekisui’s proprietary technology. Butyral resin made its debut as an interlayer for laminated safety glass. Since then, its excellent characteristics have become widely recognized, and it is now used in a wide range of products. Our S-LEC K series (special polyvinyl acetal resin) has widened the range of applications.
Main applications: Coating materials, printing inks, and adhesives

Rigid polyvinyl chloride resin with high heat resistance. It is made by chlorination of a special polyvinyl chloride copolymer and offers improved heat characteristics without sacrificing the excellent performance of a polyvinyl chloride copolymer. It also offers excellent characteristics in a wide range of applications requiring heat resistance.
Main applications: Industrial sheets, and heat-resistant pipes and fittings

Rigid polyvinyl chloride resin with excellent weather resistance and impact resistance. It is a graft copolymer consisting of rubber elastic EVA (ethylene-vinyl acetate copolymer) as its backbone, with a polymerized polyvinyl chloride graft. This copolymer combines rubber elasticity and low temperature characteristics with mechanical properties and chemical resistance. The rigidity of the copolymer can be changed over the range from rigid to non-rigid.
Main applications: Impact-resistant pipes, automobile parts, and non-rigid sheets

Expandable particles with excellent thermal characteristics. It is a thermal expandable microsphere which consists of a hydrocarbon with a low boiling point in a thermoplastic polymer cell. It assumes a hollow balloon shape by heating. It can be used as a blowing agent for many applications (PVC, acryl, epoxy, rubber, silicon, etc.) by adding it to inks or paints.
Main applications: Various types of foams
