Sekisui 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.


Industrial sheet - It has so excellent transparency & chemical resistance that one of the applications is industrial sheet
(ex. Semiconductor equipment)
Heat Flame resistant films and Heat resistant cards
Automobile Parts - Because of high heat resistance,it is suitable for moldings(ex. weather strips)
Heat resistant pipes & Heat resistant fittings
Applications for PVC-HA

Special Features

Heat resistance:

The heat deflection temperature is from 10'C to 40'C higher than that of normal PVC, and it is also resistant to hot water .
