‘Impossible’ simply does not exist in our vocabulary. We not only offer a comprehensive standard product range of fibre fillers, short cut fibres, fibrids & pulp, but also individually tailored fibre solutions according to your requirements. In order to meet your needs, we also carry out special test projects and trials. Get in contact with us. Our fibre experts will be pleased to advise you.
At STW you can choose from a comprehensive range of fibre fillers. Employing unique grinding technology, fibre fillers are made from randomly-oriented fibres, continuous fibres, threads or woven textiles, again, often according to your individual requirements, and often using fibres from the recycling sector. In this way, depending on fibre fineness and specification, we can produce products with a high degree of purity and uniform fibre length distribution.
The most important fibre fillers, at a glance:
Fibrillated fibres have mechanical properties which are the same as, or similar to, those of the corresponding fibre types in filler or short cut fibre form. Their main differences derive from their branched structure (fibrils) and their demonstrably, substantially greater surface area. Owing to these specific properties of the fibres, additional effects are derived, e.g. thixotropic properties.
The most important fibrids, at a glance:
Our short cut fibres have a defined length and are produced from continuous fibre tows made especially for STW. We work exclusively with selected fibre manufacturers who know our specifications and comply with them reliably.
With in-house-developed production processes, we cut fibre tows into short cut fibres, to which adhesion promoters are applied matched to end applications. When cutting the fibres, we only influence the fibre length, which is one of the decisive quality criteria.
The quality of our spun fibre tows which are shredded into short cut fibres, meets the very highest requirements. For this purpose, we are continually improving our multi-stage and fibre-specific comminution methods.

Among the compounds we produce, are special thixotropic agents which are homogeneously mixed with amorphous silica.
