Alok Masterbatches Ltd. has developed ultraviolet-light stabilizer systems using a nanoparticle synergist.
The New Delhi firm claims the synergist boosts UV protection by 20 percent compared with masterbatches based on hindered amine-light stabilizers and UVA absorbers. Success in polyethylene and polypropylene resin applications has spurred Alok to explore similar systems for engineering resins.
Alok also has developed Add¼nox, an additive that improves mechanical properties. In PE film and recycled PE the additive improves tear strength while allowing downgauging.
