To
meet the plethora of market demands, Sekisui is using extensive
experience and know-how to research and develop advanced resins with
ever increasing functional excellence. Please contact us soon.
Sekisui Chemical Co.,Ltd. has
developed a special method of manufacturing Polyvinyl Butyral Resin,
named S-LEC B , and Polyvinyl Acetal Resin, named S-LEC K. Polyvinyl
Butyral Resin made its debut in the United States in 1936 as an
interlayer for safety glass. Since then, the excellent characteristics
of polyvinyl butyral resins have become widely recognized, and they are
now utilized in a wide range of products, including ceramic binders,
printed wiring' board adhesives, special coatings, printing inks,
etc.In addition to S-LEC B,Sekisui has developed S-LEC K series.So they
are utilized in a wider range of products.

PVC-HA is a post-chlorinated polyvinyl chloride. It
offers improved heat resistance without sacrificing the excellent
performance of polyvinyl chloride. There are a variety of grades, from
medium heat resistance grade to
high heat resistance grade, and also a high flow grade, all with heat
resistance characteristics required for a wide range of
applications.Compounds (Sekisui Compounds SH/EH series) are
available,made of HA.

PVEVA & Vinyl Chloride Graft Copolymer
C-TG is a graft copolymer that has rubber elastic
EVA
(ethylene and vinyl acetate copolymer) as its main part, and polyvinyl
chloride graft polymerized to this.
This copolymer combines the
rubber elasticity and low temperature characteristics of EVA with the
mechanical properties and chemical resistance of polyvinyl chloride,
and by varying the content of EVA the rigidity can be changed over the
range from rigid to nonrigid.
The
various grades have characteristics making them suitable for a wide
range of applications. The Low-EVA Grade has excellent weather
resistance and is suitable for use as an impact resistant PVC. The
High-EVA Grade can be used for improving the impact resistance of
polyvinyl chloride resin, and as a non-migrating, non-volatile,
nonrigid polyvinyl chloride resin.
 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
