PET double-sided tape is a double-sided adhesive tape consisting of a transparent polyester film and acrylic adhesive. The adhesive system is especially resistant to plasticizers and offers a secure bond even at elevated temperatures. PET double-sided tape offers an excellent immediate adhesion performance to secure reliable bonding strength even to low energy substrates such as PP or PE. Polyester Films, also known as Mylar® Polyester Film, Metalized Polyester Film, PET Polyester Film, APET Polyethylene Terephthalate Film, PETG Polyester Terephthalate Glycol Film or Polyester, are flexible and dimensional stable, making it hard to tear. Typically resistant to high-temperature and UV, it is often used for electrical insulation, surface protection, and packaging. Available with or without adhesive and in a variety of finishes, from clear to silver and many other colors or tints. Acrylic adhesives can either be water-based (this is also referred to as emulsion or dispersion) or solvent-based. Water-based are slower drying compared to solvent-based systems but generally, solvent-based acrylic systems have better resistance to other solvents, chemicals, and water. Comparatively, water-based systems are less expensive than their solvent-based counterparts. Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), commonly abbreviated PET, PETE, or the obsolete PETP or PET-P, is the most common thermoplastic polymer resin of the polyester family and is used in fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.
