Based on its properties, PIB (Polyisobutylene) is used as the key formulation component for various applications. For example, its corrosion resistance is important for tank linings or pipe jacketing. PIB is highly regarded for joint and web seals. This is due to its applicability over a wide temperature range including very low temperatures (down to -50 ° C). The adjustable tackiness is used in both foil/film and hot glue applications. For packaging, especially in the food industry, its gas impermeability is ideal.
Polyolefin masterbatches containing 60+% of PIB can be produced for such applications as stretch film for food wrap, pallet wrap and other applications. Due to the physical nature of PIB (Polyisobutylene), it is not easy to work with, so masterbatches provide the market with an easy to utilize masterbatch pellet which can be let down into the percentage that is optimal for the particular application.
