Typical Applications
TEGOMER® 6850 is applied in various film processes, e.g. cast films, blown films and others. The product is suitable for transparent and matt films as well as for films containing TiO2 (white opaque films) or CaCO3.
TEGOMER® 6850 is used in fiber spinning processes to enhance the throughput and reduce fiber fraction during extrusion. It is also useful in challenging extrusion operations where a smooth surface appearance is expected, such as in pipe and profile extrusion.
TEGOMER® 6850 causes a significant reduction of the coefficient of friction (COF). At the same time the slip performance is improved. There is no transfer of the additive to the opposite layer of the film causing a lost in adhesion force or a reduced sealing strength.
TEGOMER® 6850 is suitable to replace fluorine-based polymer processing aids (PPA) to prevent the film against shark skin appearance. TEGOMER® 6850 does not contain any halogens.
TEGOMER® 6850 prevents die built up and thus, reduces the need for cleaning stops and maintenance.

Benefits at a glance
The use of TEGOMER® 6850 gives the following benefits:
In general:
If used as a COF reduction agent / slip enhancer:
If used as PPA:
In general:
- No thermal degradation
- No influence on printability
- TEGOMER® 6850 does not cause a coating of the rollers in cast film applications nor the metal dies in blown films applications resulting in less cleaning and maintenance work compared to other PPAs
- High gloss and no haze in transparent applications, which is important for graphic art films for instance
If used as a COF reduction agent / slip enhancer:
- Longer lasting slip performance even after thermal aging
- Even at very low addition levels a homogenous distribution of the OMS additive can be achieved in the finished product.
If used as PPA:
- Unlike other PPAs, TEGOMER® 6850 shows an immediate effect without start-up processes being required.
- Quick material change from one quality of film to another
- Quick color change as material does not stick to the metal walls
- No corrosive degradation products
- No issues with any release of fluorine compounds into the environment / ground water
