reSound™ REC Recycled Content Thermoplastic Elastomers (TPEs): based on post-consumer recycle (PCR) for reduced carbon footprint
Versaflex™ TPEs: can reduce vibration in consumer goods such as household appliances and power tools by up to 80% compared to traditional thermoplastic vulcanizates (TPVs)
OnFlex™ TPEs: offer high thermal, chemical, and mechanical property profiles with low odor for demanding applications in transportation, including OnFlex AF 7210-70 for automotive components with low volatile organic compounds (VOCs), low fog, and lower density compared to previous material grades, plus excellent low-gloss surface finish and soft touch for high-quality aesthetics

Using a variety of metallic fibers and
particles, these compounds have densities
similar to traditional metals, while offering
design and processing flexibility because of the
polymer matrix, which can be extruded, molded,
calendered, or thermoformed into the final
desired shape.
KEY CHARACTERISTICS
The primary features and benefits of Gravi-Tech
formulations are:
• Customized density, offering a wide range
of specific gravities from 1.2 to 11 gm/cm3
• Broad modulus range, from very flexible
to very rigid grades
• Corrosion resistance, withstanding oxidation
for long-term use and benefit
• Chemical resistance, withstanding fuels, oils
and other harsh chemicals
• Metallization and electroplating, delivering
the look and feel of metal
Additional features include:
• Design flexibility and processing ease
• Good impact strength
• Elevated heat deflection temperature

Structural foam
molding machines (Figure 1) are equipped with a
plasticizing extruder and a separate transfer cylinder
for quicker injection.

The main reason for the use of Hydrocerol Chemical
Foaming Agents is to achieve weight reduction of
plastic parts, which in turn saves material costs and
supports a more sustainable profile to the molded
part.
