Low ammonia PV NRL (PNMF8004) is a low ammonia prevulcanised NR latex of medium modulus. It is compounded with a specialized natural rubber latex without thiazole accelerator. Dipped products manufactured from Low ammonia PV NRL (PNMF8004) by conventional processing techniques should readily meet the EN71-12 standard (Safety of Toys) for the level of extractable nitrosamines and nitrosatables. All ingredients used in this Low ammonia PV NRL (PNMF8004) also complies with BGA recommendations.
Low ammonia PV NRL (PNMF8004) has been developed primarily for use in the production of balloons of the conventional dipping techniques. In addition to low nitrosamine and nitrosatables, balloons produced from Low ammonia PV NRL (PNMF8004) have good colour clarity and resistance to ageing. This PVultex can also be used for other dipped products which require low nitrosamines/nitrosatables content.
