Market Description
Isobutylene isoprene rubber (IIR) is a synthetic elastomer produced through the copolymerization of isobutylene with a small amount of isoprene. It offers a unique combination of airtightness, flexibility, vibration damping, and durability, distinguishing it from many other synthetic rubbers.
Key Market Characteristics:
-
Extremely low air and gas permeability
-
High resistance to heat, ozone, moisture, and chemicals
-
Excellent aging and weather resistance
-
Strong compatibility with fillers and compounding agents
-
Critical material for long-life and safety-oriented products
IIR is widely used in automotive components, waterproof membranes, cable insulation, sealants, and vibration-control systems. Continuous innovation in polymer modification and processing technologies is enhancing material performance and expanding end-use potential.
Impact of COVID-19 on the Isobutylene Isoprene Rubber (IIR) Market
