If you are looking for a PET film for your needs, then Mylar is one of the best brands in the market. A PET is a polyester or polyethene terephthalate. This is a thermoplastic which is made up of dimethyl terephthalate (DMT) and ethylene glycol.
It is crystal clear and offers high performance if you compare it with other polymer firms. It has greater tensile strength, low moisture absorption, strong dimensional stability and maintains its physical properties when tested under a wide range of extreme temperatures.
It also has good resistance to UV, optical clarity, good gas barrier, excellent electrical properties and high gloss. This type of film is best suited for printing and laminations. They tend to have a high melting point so it's most suited for materials that require high temperatures for sterilisation.
There are many different PET film brands in the market. One of the most common and highly demanded is Mylar. It is a film produced by DuPont Teijin Films. Here we’ll take a closer look at exactly what Mylar is and what it can be used for.
Polyester film is biaxially oriented, meaning it was stretched in two directions during the manufacturing phase of the polyester film. It is one of the best films with balanced dimensional stability allowing it to retain its properties under extreme temperatures.
There are different types of Mylar film available, depending on what your requirement is and what you are looking for. You can also include an added coating on Mylar to provide resistance against chemicals and scratches.
Mylar is a polymer film which has very specific properties.
· It has optical clarity. Its chemical makeup enables it to act as either crystalline, amorphous or a combination of the two, depending on the industry they are being used in.
· It is clear with a glossy finish. Its texture can vary, going from hazy to a rough surface or a matte finish.
· The surface has anti-glare and anti-fog properties. The makeup of the film will not change under strong sunlight or due to humidity etc.
· It can be used to change the appearance of applications or settings by treating them with various chemicals. This can improve the adhesion or coating of the Mylar.
· It has very strong heat-stabilising properties. It does not change its appearance; expand or shrink, under different temperatures. It can handle a temperature between - 70 °C to 150 °C. It has a melting point of about 200 °C.
· It has resistance to impact with high tensile strength. It allows it to be used in places where exposure to debris or force is expected.
· It is chemically inert and thus does not react with any other material.
