such as 
PVC pressure pipe, drain pipe, 
electrical conduit etc.

Tyrin - 3615

Tyrin - 7000

IM 800

Lower chlorine content, high molecular 
weight, excellent physical property,
 faster gelation, most suitable for
 mixing with AIM 
as impact modifier or complete 
substitution of AIM.

Super quality PVC window profile, 
improved low temperature 
properties and corner-weld strength.
