APPLICATIONS:


Rigid PVC Pipes: As the filler loading increases the more active
heat stabilizer with more metallics is recommended. PP-2 is recommended
for scrap pipes and very low filler pipes on twin screw. For single
screw machines and twin screw moderate to high filler machines PP-3 is
the optimum grades whereas PP-4 is recommended for high filler pipes on
single screw machine.
