Butyl rubber is a synthetic rubber made from the polymerization of isobutylene, often with a small amount of isoprene. It is known for its excellent impermeability to gases, making it ideal for applications like inner tubes in tires and seals. Its durability and resistance to aging, UV light, and chemicals also contribute to its widespread use in various industries. This versatile material is commonly used in the production of adhesives, coatings, and medical supplies. Additionally, butyl rubber is valued for its low-temperature flexibility and high resilience, making it suitable for both industrial and consumer products.
