Easy-to-handle films

Evonik solutions for processing and handling polymer films

  • Anti-blocking agents

Evonik offers tailored silica products as processing aids for smooth and interference-free processing, consistent quality, and convenient handling of polymer films. SPHERILEX® and SIPERNAT® silica grades provide a strong anti-blocking effect, which is crucial in most all film applications, from industrial film production and processing all the way down to the end-use.  In addition, they offer specific advantages in a wide range of film types such as PE, PP, PET, PA and PVC films.  

Adding silica keeps films from sticking together. Silica particles are incorporated into the film matrix, where they form a micro-rough surface that reduces the contact area, thus preventing adhesion and improving the film's gliding properties. This is essential for blown and cast film production, winding, refining, tailoring, and end-use of films.
