OTPEs Deliver Performance,
Processability and Recyclability
Thermoplastic elastomers are steadily replacing thermoset rubber in
demanding automotive applications because they enhance rubber's benefits with
the design freedom, streamlined processing and recyclability of thermoplastics.
For example, Multiflex® styrene-ethylene-butylene-styrene (SEBS)-based TPE
compounds from Multibase, a Dow Corning Company, combine an SEBS rubber to
achieve softness and resilience and a polyolefin for easy processing and
Multibase's TPEs help you address top challenges such as cost reductions
through streamlined processing. For instance, Multiflex TPE compounds can be
easily co-injection molded with a structural plastic to produce a cowl vent
with a bonded TPE seal.
In addition to processing benefits vs. thermoset rubber, the Multiflex
family of TPE compounds offers:
Excellent colorability and aesthetics and resistance to color degradation,
particularly after exposure to UV radiation
Low compression set within a wide temperature range
High fatigue resistance
Excellent resistance to alcohols, acids, aqueous solutions, bases and
High thermal properties
Dow Corning offers these materials in a range of hardnesses (20 Shore A
to 50 60 Shore D) and densities (0.90 g/cm3 to 1.20 g/cm3). They maintain high
performance when exposed to temperature extremes from -50 °C to 120 °C.
Solving Your Application
Due to their proven performance, Multiflex TPEs are widely used in
industrial sectors such as:
Window and doors seals
Interior and exterior Automotive
Product highlights include:
Multiflex® TPE A6221 CUV - This easily colorable, UV-stable TPE provides
unique, long-term performance for many indoor and outdoor applications, such as
automotive parts, that are exposed to prolonged, direct sunlight.
Multiflex® TPE SiE A 4013 CU1 - Resistant to scratching and UV light, this
silicone-enriched TPE is well suited for a variety of interior and exterior
applications, including vehicle components where maintaining aesthetics is
Multiflex® TES XX10 series (Hardness ranging from 47 to 91) - Also designed
for indoor and outdoor applications, this styrenic-based TPE family resists
degradation from UV rays.
