  Chemistry of Polymers
  The research projects of the previous years resulted in the finding that the properties of coatings and compound materials could be designed more functional and improved in quality if one succeeded in integrating additional "functions" and avoiding compatibility problems occurring. This can be achieved for instance through a targeted chemical modification of the polymers involved in the composite structure and/or with customised additives. The department "Chemistry of polymers" which is currently set up rises to this challenge.

  Leather and Leather Processing
  Besides wool, stone and wood leather is one of the oldest natural materials in human history. It has always been used as protective and decorative clothing but also as technical material. Today, leather has nearly vanished from technical applications. But despite numerous substitutes leather continues to be popular with the automotive, furniture, shoe and fashion industries thanks to its precious and natural character. And as sustainability and ecology play an important role in particular in these industries, there are consistently new approaches for research topics.

- Collagen
  Collagen
  Collagen is the most important structural protein in animal organisms. It forms fibres and fibre networks and provides shape and stability for organs and tissues. It can be extracted from hides, tendons, ligaments and other tissues and serves as biopolymer for the manufacture of a large number of products. Depending on the method it can be processed into films, threads, non-woven fabrics, tubes or 3D moulds. Collagen-based products are applied in numerous fields such as the food production industry (sausage casings, pet food), the cosmetics industry (collagen hydrolysates), the pharmaceutical industry (drug delivery) or medical engineering (wound dressings, implants, suture material, tissue engineering).

  Leather is undisputedly one of the oldest materials in the history of mankind, one could also say it is as old as mankind itself. The natural material has always been used to make protective and decorative products for mankind. In the absence of plastics, leather was above all an important technical material for transport containers, tools, packaging, bellows, drive and transmission belts or gear wheels.

- Coated Textiles + Plastic Roll Goods
  Coated Textiles + Plastic Roll Goods
  The coating of textiles for producing flexible compound materials dates back to the middle of the 19th century when three scientists simultaneously discovered guncotton, a white, fibrous, odour- and flavourless mass. At first it was used for the manufacture of artificial silk, later for coating films (celluloid) e. g. on films and textiles. Due to its explosiveness the substance can still be found in explosives today.

- Functional Coatings + Composites
  Functional Coatings + Composites
  A composite material in general is a material consisting of two or more basic materials which are combined with each other. The materials are combined by adhesive bond or form fit or by a combination of both techniques. The aim of producing composites is to obtain a material which combines the properties of its components, thus receiving the properties of the composite material.

  Collagen + Biogenic Materials
  Did you know that collagen can develop a tensile force of 100 megapascal if water is eliminated, which is 300 times as much as that of a muscle. Human as well as animal bodies above all owe their strength this fibre-forming protein, the collagen. Large amounts of it are contained in bones, tendons, ligaments or the skin. Like all proteins, collagen is composed of a complex arrangement of individual components hierarchically, too.

  The modern medicine can no longer be imagined without biomaterials. Biomaterials are synthetic or natural, non-living materials which are determined for therapeutic or diagnostic purposes for short- or long-term retention in a body, or which come into contact with it on its surfaces. In any case there are interactions between material and biological system.

  Plastics + Elastomers + Foils
  Although plastics had captured the world since the middle of the 19th century, there were only a few information about the exact structures of polymer materials at first. From vapour pressure and osmosis measurements one only knew that very large molecules with a high molecular mass were involved here. Erroneously, one thought that these are colloidal structures.

  Textiles + Yarn
  A textile is a laminar, two- or three-dimensional, flexible material mainly consisting of one or more yarns and is produced using a textile technique. Yarns used for the manufacture of textiles consist of individual fibres of different origins for instance vegetable, synthetic or mineral origins. In addition to clothing, textiles can be found today in almost all industrial applications.

  Trendsubstitutes
  During the past years we have encountered materials more and more frequently, which are to substitute the traditional leathers and coated textiles. Background is a growing need of consumers for products which do without raw materials of fossil or animal origin. There are very different approaches concerning the raw material base and the selected technologies.

Hydroxyproline content

Hydroxyproline is an amino acid that is chemically bound in collagen. The collagen content can be determined from the hydroxyproline content depending on the animal. This is an important quality criterion for applications in the medical sector.
