Silicone Profiles/sponge Silicone Seal Strip For Window Door
What is a Silicone Sponge Seal Strip?
A Silicone Sponge Seal Strip (also known as a silicone foam profile or closed-cell silicone gasket) is a flexible sealing material made from expanded silicone rubber. It features a closed-cell structure, meaning the air bubbles inside are completely separated from each other.
This structure gives it key properties: non-water-absorbing, excellent rebound resilience, softness, and long-term durability.
Think of it as a high-density foam that is far more heat-resistant, weather-resistant, and durable than ordinary sponge or rubber materials.
