Polymer-Chemie at K 2007
Focus on innovative glass fibre-reinforced PVC compounds
Bad Sobernheim/Germany, July 2007 – Newly developed glass fibre-reinforced PVC compounds as
well as compounds with improved general properties will be the focal point of the presentation of
Polymer-Chemie GmbH, Bad Sobernheim, at this year's "K" in Düsseldorf. Among the innovations
of this company's Business Unit PVC Compounds will be both glass fibre-reinforced PVC
compounds and, as a première, long glass fibre-reinforced compounds with PVC as the matrix
material. Manufactured by a special process, which has been developed on the basis of many
years' compounding experience and expertise, these compounds offer manifold advantages for
applications in a great diversity of industries. For example, the newly developed long glass fibrereinforced PVC compound – the strands are of pellet length – can be used for the production of
window frame reinforcing sections capable of replacing parts hitherto manufactured in metal.
Besides their weight-saving advantage, these reinforcing sections not only improve thermal
insulation but also open up new design possibilities. The scope of R & D work also includes
compounds with sustainable raw materials. A further exhibition theme is "Fillers with a Function". In
this context, Polymer-Chemie's presentation will include new graphite-filled compounds for a whole
range of applications, from packagings for electronic products through to moulded structural parts
for use in the construction industry. All PVC compounds can be processed by the usual methods,
e.g. extrusion and injection moulding.
Especially in the case of long glass fibre-reinforced compounds, gentle but thorough dispersion is
absolutely essential. Homogeneous dispersion – without causing excessive breakage of the fibres –
is a decisive factor for such part properties as high impact resistance, strength, rigidity and heat
resistance. Backed by many years' compounding know-how, Polymer-Chemie has developed a
process that ensures an uniform embedding of the strands in the matrix, beginning with a special
pretreatment of the continuous strands prior to their introduction into the compounding line, where
they are gently worked into the PVC matrix. The resulting rod-shaped pellets feature strands of full
pellet length. These compounds are available under the trade name SorVyl® with different pellet

lengths and hence different strand lengths and different glass fibre contents. In addition, PolymerChemie also develops both long glass fibre-reinforced and chopped strand-reinforced compounds –
like most of its SorVyl® compounds – to customers' specifications. To this end, the production
facility in Bad Sobernheim operates a new, fully equipped state-of-the-art pilot plant (twin-screw
extruder). Thus Polymer-Chemie will also be presenting itself at "K" as a partner in the development
of customized formulations.
The Business Unit PVC Compounds of Polymer-Chemie GmbH develops, produces and markets –
under the trade name SorVyl® – both unplasticized PVC compounds (pellets and dryblends) and
plasticized PVC compounds. Its fifteen production lines together have a compounding capacity of
around 70,000 tonnes/year. These compounds enjoy application in numerous branches of industry,
from the building and automotive industries through to the electrical engineering and household
appliance industries.
Established in 1973, Polymer-Chemie GmbH, is an independent, privately owned company serving as a link
between raw material manufacturers and the plastics processing industry. The parent factory at Bad
Sobernheim has a capacity of 150,000 tonnes/year for the compounding, improving and modifying of
polymers. With its customized developments and its own new formulations and innovations, Polymer-Chemie
can offer its customers all over Europe solutions tailored specifically to their requirements.

Polymer-Chemie at K 2007: Focus on innovative glass fibre-reinforced PVC compounds
The newly developed long glass fibre-reinforced PVC compounds from Polymer-Chemie with
strands of full pellet length can be used for a multitude of applications, e.g. window frame
reinforcing sections for PVC windows. Besides the required strength and rigidity, these reinforcing
sections feature negligible thermal conductivity and hence give considerably better thermal
insulation than the metal sections used hitherto.
