Silicone PET Film

PET Protective Film is a polyester-based film which is coated with acrylic water or silicone glue on one side. It is designed to offer a protective layer to the surface of a variety of materials, such as stainless steel and aluminum, helping to guard against scratches, dirt, and other contaminants. It can also be attached to release film as needed, providing further protection and making it easier to handle. PET protective film is a great choice for industries where is need an effective, long-lasting protective solution.

  • Good temperature and weather resistance (attached to the surface of high-gloss plastic part, adhesive surface, no abnormality in 100℃ environment for 72 hours);
  • Glue viscosity is not easy to change;
  • Easy to die cut and can be widely used in many industries;
  • No residual glue left and tearing off;


PET Silicone Protective Film Uses

  • Good transparency and good self-adsorption effect, automatic bubble discharge
  • For the actual model, there are a variety of thickness and viscosity products to choose from
  • The glue has stable performance, high temperature resistance and can be used for a long time in a high temperature environment;
  • No glue residue after tearing up, good acid and alkali resistance;
  • The sticking principle of exhaust adsorption makes it more suitable for high gloss mirror, surface protection of products with strict cleanliness requirements;
  • Double-layer structure, the special release substrate protects the rubber surface while reducing the cost, which is convenient for promotion in the electronics industry. 

How to Distinguish Acrylic PET Film and Silicone PET Film

To differentiate between acrylic PET films and silicone PET films, it is important to first understand the differences in their properties. The majority of PET films used today are silicone films, and silicone PET films are more widely used than acrylic PET films. PET films for mobile phone screens are all silicone based PET protective film. And silicone PET films are more temperature resistant than acrylic type. Acrylic PET film is a cost-effective and powerful plastic film that is mainly used for packaging and as a film for protecting goods.

If there is one roll of PET protective film, how do you differentiate between acrylic and silicone protective films? The easiest and quickest way is to scratch the adhesive side of the protective film with your hand: no gum or powder is silicone type, otherwise, it is acrylic, which is why silicone is also called powder-free glue.

In addition, the main differences between PET silicone protective film and PET acrylic adhesive protective film are:

  • In terms of clarity, acrylic is better than silicone.
  • Acrylic is very sticky and has adhesive stains after tearing off, while silicone is less sticky and has no adhesive stains after tearing off.
  • Silicone has good temperature resistance, easy to manipulate the flatness of the adhesive surface and good ultra-low temperature characteristics. The acrylic adhesive is easy to produce, good clarity, cheap, good ageing resistance and strong adhesion.
  • Put the protective film on the surface of the object to be affixed, use your finger to gently point, fast bonding without or less bubbles is silicone, slow bonding and will cause bubbles is acrylic adhesive.
