Lubricants for gears (less metal wear, thickening behavior, shear stability, clean combustion
Two stroke oil (no engine deposits, low smoke emission)
Greases (good adhesion)
Metal working fluids (n-toxic, less odor, clean burning)
Oil additives (to improve viscosity index)
Adhesives and sealants (Tackifer, peel adhesion, plasticers and wetting agent)
LDPE wrapping films (improves tack and film barrier properties),
rubber (processing aid and iI improves flexibility, impact strength, clarity, and stress crack resistance), corrosion protection paints, cosmetics such as lip gloss, asphalt applications, plastic compounds, electrical insulation in wires & cables, mould release compounds, caulks and food additives (Gum base).
Almost all PIB polybutenes grades meet the requirements of the FDA (Food and Drug Administration) for direct food contact or incidental or indirect additives applications.
Use of polybutenes mentioned by FDA regulations include plasticizers for food grade polyethylene and polystyrene, coatings for metals, components of paper and lubricants for machine used in food processing.
Many PIBs can be used in lubricants with incidental food contact (H1 – NSF certification) for use in and around food processing areas. May be used on food processing equipment such as a protective anti-rust film, as a release agent on gaskets and seals of tank closures, as a lubricant of machine parts and equipment in locations in which there is a potential exposure of the lubricated part to food.
