Inorganic Process Aids

It has been claimed that boron nitride allows much faster production rates with metallocene LLDPEs than fluoropolymer process aids. American Ceramics is one supplier. 

Some grades of calcium carbonate filler have the ability to increase throughput rates. 

PVC Alkyl /aryl phosphates Flame retardant flexible compounds 

PVDC Tributyl citrate Food wrapping film 

Cellulose acetate Acetyl triethyl citrate Biodegradable film

In conclusion, the yellow contamination appears to be a mixture of materials, their infrared spectra suggesting that they are primarily a vegetable oil and pullulan, with possibly a surfactant and maybe an inorganic pigment also being present. The green residue is consistent with a saturated aliphatic hydrocarbon, such as a processing aid or an oil. 

Brosco-Nol . [SchoUer] Blends d inorganic salts and sequestrants or blends of nonionic and high polymeric compounds processing aids, activators, war ter sofKmrs, sequestrants, compatibi-lizers, corrosion inhibitors for textile industry. 

For processing aids necessary for the production of edible oils, a proposal was elaborated by Codex Alimentarius Fats and Oil Committee. The materials proposed in this list (inorganic acids, alkalis, solvents for extraction, bleaching materials) are not dangerous for health.
