Foam tape is a type of double-sided adhesive tape made with a soft foam material that serves as an excellent cushion and sealant. The varying densities of foam allow for flexibility, ensuring that the tape can conform to irregular surfaces, making it effective for a wide range of uses. Typically, foam tape is constructed from materials like polyethylene, polyurethane, or EVA (ethylene-vinyl acetate), each contributing unique properties such as durability, resistance to moisture, and excellent adhesion.
