Polyester Film Tape (PET Tape)

Shielding Laminates

Vacuum Metallized Films & Fabrics

Copper/PPS shielding tape is an electrical insulating tape made from PPS film with excellent chemical and heat resistance, where PPS plastic (polyphenylene sulfide) is a high-performance thermoplastic engineering plastic known for its excellent properties, including high temperature resistance, corrosion resistance , and superior mechanical properties.

Features

  • Ease of Coating
  • Flame retardant, radiation resistance, and thermal insulation.
  • High-temperature insulation
  • High adhesion strength and dielectric strength
  • Outstanding voltage resistance and tensile strength
  • Perfect balance of electrical, chemical, and physical properties

Applications

  • Thin and heat-resistant parts for fastening and electrical insulation
  • Used in TAB bonding (tape automatic bonding), heat-resistant films, etc
  • Flame retardant materials
  • Thermal insulation materials
  • Data transmission cable
  • EMI shielding

Advantages of PPS

  • Dimensional stability
    PPS film can maintain its dimensions and shape even when exposed to high temperature and high humidity thanks to its minimum molding contraction rate and thermal expansion.
  • Electrical properties
    PPS film has superior electrical insulation properties, making it suitable for applications needing to exposure to high humidity, high temperature environments.
  • Chemical resistance
     One of the significant advantages of PPS is its outstanding chemical resistance. PPS exhibits strong resistance to a variety of chemicals, such as acids, bases, solvents and fuels.
  • Mechanical properties
    PPS film has high strength and high rigidity with minimum degradation at high temperatures. Additionally, it has excellent resistance to creep and fatigue, thus making it can bear heavy loads and resist deformation.

PTFE film tapes are used as non-stick coatings due to their high heat resistance and non-stick properties, and are often suitable for frying pans or other types of cookware. Because of its non-conductive properties, PTFE film tape is also ideal as an insulating material for electrical applications.

Shielding laminates are often categorized based on the type of matrix material used. The four main categories of shielding laminates are Polymer Matrix Composites (PMC), Metal Matrix Composites (MMC), Ceramic Matrix Composites (CMC) and Carbon Matrix Composites (CAMC).

Metal shielding laminates are produced by continuously bonding two thin metal sheets or natural metal films to one side of a thermoplastic core. These cores form sheets that are lighter in weight, easy to fabricate, flat and durable.
 
Slightly oxidized copper foil surfaces can be cleaned using an alcohol sponge. However, for long-term or extensive oxidation, a sulfuric acid solution is required to clean and remove oxidation.
