Toupee tape Invisible double-sided tape used to attach hair pieces or to hold delicate fabrics against the skin. Reflective tape High-visibility adhesive tape with retroreflective sheeting. Thread seal tape Polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. Ultra-high-molecular-weight polyethylene tape
PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]
Some PTFE parts are made by cold-moulding, a form of compression molding. [44] Here, fine powdered PTFE is forced into a mould under high pressure (10–100 MPa). [ 44 ] After a settling period, lasting from minutes to days, the mould is heated at 360 to 380 °C (680 to 716 °F), [ 44 ] allowing the fine particles to fuse ( sinter ) into a ...
Box-sealing tape, parcel tape, packing tape, or shipping tape is a pressure-sensitive tape used for closing or sealing corrugated fiberboard boxes. It consists of a pressure-sensitive adhesive coated onto a backing material which is usually a polypropylene or polyester film which is oriented to have strength in both the long (machine) direction ...
PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE), whereas PTFE is a homopolymer of tetrafluoroethylene. The monomers of the former differs from that of latter structurally by having a chlorine atom replacing one of the fluorine atoms. Hence each repeating unit of PCTFE have a chlorine atom in place of a fluorine atom.
Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.

Release agents provide a barrier between a molding surface and the substrate, facilitating separation of the cured part from the mold. Without such a barrier, the substrate would become fused to the mold surface, resulting in difficult clean-up and dramatic loss in production efficiency.
