Molded Butyl rubber is often used for outdoor applications because of its excellent weather and abrasion resistance. Also recommended for its ability to resist gases, inorganic acids and alkalis. Butyl is a non-pliable polymer/elastomer. 

Butyl has excellent sealing properties and is a suitable choice for the manufacture of seals for chemical condensers. It is widely used in the electronics industry.

- Good sealing properties
- Resistant to electrolyte solvents
- Low compression set
