Moisture Uptake

Under general atmospheric conditions of 50% relative humidity (RH), APTIV 1000 film shows low moisture absorption. As a result APTIV 1000 film exhibits stable mechanical, dielectric and dimensional properties.

Tensile Modulus

APTIV 1000 film has excellent tensile modulus. Further enhanced mechanical properties, if required, can be achieved by using the mineral-filled APTIV grades.

Hydrolysis Resistance

APTIV 1000 film demonstrates exceptional stability in mechanical properties when exposed to a high temperature and high humidity environment. This results in excellent retention and minimal variability in the mechanical performance of the finished product.

Radiation Resistance

Considering the oxidative gamma radiation dose above which significant deterioration of flexural properties starts to occur, VICTREX PEEK polymer exhibits excellent resistance to radiation.

Puncture Resistance

Both APTIV 1000 and 2000 film grades demonstrate excellent puncture resistance compared with other high temperature polymers.

Dynamic Coefficient of Friction

APTIV 1000 film has very good low dynamic coefficient of friction compared to other engineering polymers, making it an ideal choice for wear applications. APTIV 1000 film combines very low particle generation with excellent abrasion resistance.

Tear Resistance

APTIV 1000 film has excellent tear resistance properties combining strength from the crystalline phase and ductility from the amorphous phase.

Abrasion Resistance

APTIV 1000 film exhibits excellent abrasion resistance. The graph below shows the very low wear rate of APTIV 1000 under abrasive load when compared with other films.

Gas Permeation

APTIV 1000 film has very good resistance to gas permeation including oxygen and water vapor. It can also be metallised or coated with other suitable barrier material to further reduce the gas permeation if required.

Dielectric Strength

APTIV 1000 film has very good dielectric strength properties allowing it to be used in a variety of electrical insulation applications.

Dielectric Constant

APTIV 1000 has very good dielectric properties for use in electrically insulative applications.
