Butyl has very low permeability to air and other gases.

APPLICATIONS:

Pre-sulfurization rubber lining Brominated butyl

It’s widely used in acid-base storage tanks which can avoid strong acid/base corrosion. It stands out for its excellent impermeability to gases.

This characteristic, together with its flexibility and weather resistance, makes it a habitually-used rubber for numerous industrial applications.

Butyl sheeting is also essential for seals and protection in chemical industries where high concentrations of mineral acids and alkalis occur such as phosphate plants, fertilisers, caustic soda, etc.

And also used for Gaskets or washers cutting and manufacturing of pieces for general purpose applications.
