New compounds for the automotive industry
Crosspolimeri is a company seeking
to satisfy that part of the compound
market that requires ready prepared and
tailor-made special compounds.
Crosspolimeri is specialised in producing
thermoplastic and cross-linkable com-
pounds with and without flame-retardant
and halogen-free properties. The indus-
trial fields of electrical cables, tubes
and technical parts for the automotive,
aeronautical and railway industries,
consumer goods and communication
systems offer a multiplicity of applications
and are the main market for the
Crosspolimeri compounds.
Compound production is at Crosspolimeri SpA located in Italy, where several polyvalent
production lines have a total capacity of 12,000 tons per year. A sister factory,
Crosspolimeri AG, located close to Basel (Switzerland), will be in position to produce
12,000 tons per year from 2009. Crosspolimeri’s main competence is in cross-linkable
compounds, unfilled and filled (in order to give different characteristics and flame
retardant value).
Recently the company has researched new thermoplastic compounds that perform
similarly to cross-linkable products. The research was carried out in medium tension
and especially in the automotive field. Crosspolimeri is in position to present new
compounds for this sector, meeting T2 – T3 – T3S specifications.

Vinyl elastomers provide rugged performance
under aggressive conditions
The Vinyl Division of Teknor Apex Company has developed new grades of its Flexalloy®
vinyl elastomer with improved flame retardance and even better low-temperature
properties than established Flexalloy compounds.
The new Flexalloy products are recommended for cabling applications such as
alternative energy systems and satellite dishes.
The PVC resin on which all Flexalloy compounds are based consists of ultra high
molecular weight (UHMW) PVC rather than the standard PVC polymer in nearly all other
vinyl compounds, including those widely used for wire and cable. This high-performance
UHMW resin, combined with Teknor Apex’s proprietary compounding technology,
enables Flexalloy compounds to stay flexible at very high and very low temperatures,
withstanding extreme cold, searing heat, and wet environments without cracking,
softening, or compromising the integrity of the cable.
Flexalloy products are suited for use in harsh outdoor environments and in challenging
applications, such as power cords, that must conform to UL wet-location standards for
flammability.
Flexalloy vinyl elastomers also represent an attractive cost-performance alternative
to many styrenic and olefinic thermoplastic elastomers (TPEs), providing comparable
compression set and other rubber-like properties.
