Division rubber, also known as divider rubber or sealing strip, is a flexible strip typically made from materials like rubber or silicone. It is used to create a barrier or separation between two surfaces, preventing the infiltration of dust, moisture, air, or other unwanted elements. Division rubber is commonly employed in applications such as windows, doors, and automotive compartments to seal gaps and enhance insulation. It comes in various shapes and sizes to accommodate different spaces and is valued for its durability and weather resistance.
