Chemigum® and Sunigum® powdered elastomers have been used to
tailor-make thermoplastic elastomers (TPEs) in blends
with different types of plastics for flat and rolled
applications, such as membranes, synthetic leathers,
automotive interior skins…etc.

Chemigum® elastomers enhance flexibility, oil
resistance, abrasion resistance
and 'rubber-like' appearance. They also help
to retain plasticizers, thus maintaining physical
properties after severe aging.
An important
benefit of the Chemigum® elastomers
is the ability to enable deep-draw
during thermoforming without the
risk of uneven thinning and pin holing
of skins. In addition, it also improves
the embossed grain retention of the
calendared skin during the service
life of the product.
Sunigum® elastomer is intrinsically resistant to degradation by heat and Ultra-Violet
(UV) radiation. It enhances oil resistance and soft
touch of the TPEs.

ABS, ASA, SAN |
| |
Thanks
to its chemical composition, Sunigum® elastomer is naturally a good candidate
for the modification of ABS, ASA
or SAN resins. Sunigum® elastomer
extends the application possibilities
of these resins by lowering the hardness
and bringing soft touch characteristics.
This type of blend is used to manufacture
soft flexible skins for the automotive
industry or semi-rigid thermoformed
soft/hard composites.
TPU/COPE
Sunigum® elastomer
modification of thermoplastic polyurethane
(TPU) or Co-polyester (COPE) provides
a way to lower the hardness and the modulus,
improve softness and lower gloss if needed.
Sunigum®/TPU blends are particularly used
for skin and leather applications where
Sunigum® improves processing characteristics
in both extrusion and calendering.
POLYOLEFINS
Thanks
to the development of compatibilization
techniques, Sunigum® elastomer can
be used as a modifier of many polyolefins.
Improved aesthetics (soft touch),
PVC-like drape properties and HF
weldability are the main advantages
associated with these types of blends.
The Sunigum® product range includes
pre-compatibilized grades in the
form of pellets for direct and easy
blending with olefins.
