Sekisui PVC-HA
   
  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.

  Applications   Special Features
 
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
 
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 .
Properties and technical data > data 1
Mechanical strength
Excellent tensile strength and rigidity at high temperatures .
Properties and technical data > data 2 , data 3
data 4 , data 5 , data 6
Chemical resistant
Resistant to acid, alkali, and most other chemicals in the same way as normal PVC, and this resistance is particularly good at high temperatures.
Properties and technical data > data 10
Fire resistant
Better than that of normal PVC, it has the best fire retardance of any thermal plastic resin. >
Applications Industrial sheet
Moldability
With just slight modifications to the molding conditions for normal PVC, all PVC molding machines can be used as is.
Workability
Bending, cutting, jointing and other operations are about as easy as PVC.
