Impermeability: Butyl rubber exhibits exceptional impermeability to gases, making it ideal for applications where airtight seals are crucial. This property makes it popular for use in tire inner tubes, tubeless tire liners, and seals for a variety of applications.

Chemical Resistance: It has excellent resistance to many chemicals, including acids, alkalis, and oxidizing agents. This property makes it suitable for applications in industries where exposure to harsh chemicals is common, such as in the chemical processing and pharmaceutical industries.

Weather Resistance: Butyl rubber maintains its integrity in various weather conditions, including exposure to sunlight, ozone, and extreme temperatures. This weather resistance makes it a preferred material for outdoor applications such as roofing membranes and seals for windows and doors.

Flexibility and Elasticity: Butyl rubber is highly flexible and elastic, allowing it to maintain its shape and performance even under repeated stretching and bending. This property makes it suitable for applications where resilience and durability are required, such as in automotive components and vibration isolation mounts.
