(Safety Guide) The tape’s susceptibility to heat means that it is inappropriate for use in microwaves and dryers. The heat (140 ℉ and above) melts it, and UV light breaks down the bond with time.

This was added to the initial design to prevent shearing. There is a fabric (typically low thread count), which is why the tape is cloth-based. This plastic layer helps hold everything together and adds some water resistance to the tape. The plastic layer is polyethylene, which is also used for bottles. What It Is Made Ofĭuct tape is composed of three layers: plastic, cloth, and adhesive. The tape has a plastic coating on the non-sticky side, giving it a synthetic feel and shine. ![]() You likely think of duct tape in its silver form, but there are a variety of colors (from all brands) available to suit your needs. ![]() However, using duct tape to seal ducting has been inappropriate for many years.
