15 years of Styroflex

Styrolux was produced on an industrial scale for the first time about 30 years ago in Ludwigs­hafen, Germany.

In 1990, just ten years later, a second plant for this styrene-butadiene block copolymer was built in Antwerp, Belgium, and this was followed by another production site in Alta­mira, Mexico. A variant from this product family, the TPE Styroflex, was launched 15 years ago.

The product has recently made its way into the manufacture of stretch hoods. Even after being stretched by 220%, a composite packaging film having a thin central layer made of Styroflex once again clings to the packaged items. Originally developed as an alternative to soft PVC, the material is now being employed in numerous fields. Transparent meat packaging, for example, is often made of stretch or cling film containing TPE.

As a toughness modifier, it improves the application properties of HIPS and ABS. In multilayered films, it also serves as a bonding agent in combination with polyolefins and other styrene plastics. In addition, Styroflex is the soft component in the multi-component injection-moulding of soft-touch systems such as baby toys and wet electric shavers.

Its polarity ensures that the material can be easily printed on and adheres to many materials such as PC, PMMA, polyolefins as well as other styrene copolymers.
