The elastomeric sealants market is expanding rapidly due to their ability to provide flexible, durable, and weather-resistant sealing solutions. These sealants are critical in construction, automotive, aerospace, and electronics industries, where movement, vibration, and environmental exposure are common.
What Are Elastomeric Sealants?
Elastomeric sealants are rubber-like compounds that maintain flexibility and integrity even after curing. They can stretch and return to their original shape, making them ideal for joints that expand or contract due to temperature fluctuations or structural shifts.
Common types include:
Polyurethane
Silicone
Polysulfide
Silyl-terminated polyether (STPE)
