An anniversary like this is not celebrated every year. While many plastics influence our lives on a daily basis, only very few manage to become truly iconic. Polystyrene in its foamed form, Styropor^®, has accomplished this. 70 years ago, the first patent on foamed Polystyrene was granted. The brand name Styropor^® became immortal and Styropor^® became a synonym for a whole class of products. Haltermann Carless would like to congratulate BASF on this very special anniversary!

Polyurethane or polystyrene insulation boards can be foamed using various processes. Which process is used is primarily a matter of ecological and economic considerations. Pentanes are the foaming agent of choice. Their high performance and sustainability are particularly convincing. In this blog article, find out which products are currently used in the insulation industry and what increasing role Pentanes are playing in the production of insulation materials.

The insulation industry plays a crucial role in energy transition. More efficient insulation for refrigerators and freezers or even pipe insulation contribute to achieving our climate goals. Particular emphasis, however, is placed on building insulation. Improving energy efficiency in buildings is therefore crucial in achieving the ambitious goal of carbon-neutrality by 2050, set out in the European Green Deal. Find out here why this will only work with high-quality Pentanes and reliable suppliers.

Pentanes are mainly known as blowing agents for insulation materials. But they can do even more: the three isomers n-Pentane, iso-Pentane and Cyclopentane can each show their advantages in a wide variety of applications, either on their own or as a blend. In this article you can read about the differences between the three Pentane isomers and the applications in which they have proven to be particularly useful.

Polystyrene is a plastic polymer that is used in many areas of everyday life: be it for yogurt containers, packaging materials, toy bricks or for insulation purposes in building and construction. Probably the best-known use, however, is foamed polystyrene, also known as Styropor^®. We have taken a closer look at this special material and answer questions about the production, properties, use and recycling of polystyrene in this article.

The processing of polyurethane into a foam opens up various possible applications. As an all-rounder for sealing, bonding and insulating, PU is mainly used in the construction industry. The food industry also benefits from the good thermal and cooling insulation properties. In this article, you will learn all about the production of PU and PIR foam, the areas of application and how they are to be considered from an ecological point of view.

Polyurethane surrounds us in almost all areas of life. Whether in shoes, surfboards or as a high-performance insulating material, polyurethane's versatility allows it to be used in a wide variety of forms and functions. In this article, learn what polyurethane is, how it is manufactured and how its properties can be adapted to individual needs.
