Silicone Release Films
Hostaphan® Polyester Films
Hostaphan® silicone coated PET films are characterized by their outstanding release properties in combination with inherent polyester film characteristics such as high mechanical strength, low shrinkage, clarity and chemical resistance.
Extremely high levels of curing of the silicone layer on the PET film minimizes the issue of back side transfer, which is known to be present in most off line coated release materials. The silicone system is extremely well anchored to the film surface. The release force of our film is tuned to fit most standard adhesives (in particular water based acrylic adhesives), but can be adjusted to customer needs over a wide range from easy to tight release.
Our silicone release film is used in applications such as:
- Release liner for pressure sensitive labels
- Release liner for shingle release
- Release liner for cast polymer materials
- Process liner for adhesive tape manufacturing
- Release film in electronic applications
- Process liner where a separation is needed during manufacturing or storage
- Release liner in the production of ceramic capacitors
- Release liner for the window film market
