Unique Thermoplastic Elastomers
TPSiV® thermoplastic elastomers from Dow Corning combine the
strength, toughness and abrasion resistance of any thermoplastic elastomer with
the desirable properties of silicone: softness, silky feel, resistance to UV
light and chemicals , and outstanding colorability. These unique materials
incorporate vulcanized silicone modules in a thermoplastic matrix, and like
traditional thermoplastic vulcanizates (TPVs), they can be recycled and reused
in your manufacturing processes.
Dow Corning offers you several TPSiV product families in durometer
hardnesses ranging from Shore A 50 to 80, and can engineer custom grades from
any thermoplastic resin to meet your specific requirements. Adding to their
versatility, our materials can be manufactured using standard thermoplastic
processes, including overmolding or coextrusion with rigid plastic substrates
such as PC, ABS, PA and PP.
Solving Your Application
The performance properties, safety and aesthetics of Dow Corning's
TPSiV materials make them ideal for wearable
electronics such as smart watches, fitness bands, health monitors and
earbuds. Other target applications include housings, handles, buttons, battery
covers and accessory cases for consumer electronics such as handheld devices
and home appliances. You can also use them for flexible pipe connections in
potable water systems.
Our TPSiV portfolio offers important benefits, including:
Non-tacky Feel that Resists Dirt. TPSiV materials contain no
plasticizers that can create surface stickiness. Instead, the silicone itself
acts as a softening agent.
Skin Contact Safety. TPSiV grades have been shown to be
non-irritating and non-sensitizing in skin contact applications, and have no
evidence of systemic toxicity, according to standards such as USP Chapter
<88> and ISO 10993-10.
Exceptional Aesthetics. These materials can be custom colored and
deliver long-lasting colorfastness, even with exposure to sweat, oil, UV light
Silky Touch. TPSiV materials combine silkiness and softness for
comfort and wearability.
Product highlights include:
Dow Corning® TPSiV 4000 Series: A range of
UV-stable, colorable thermoplastic elastomers.
Dow Corning® TPSiV X5300 Elastomer: A material for flexible
tubing that complies with the DVGW W270 technical standard for microbial growth
in potable water.
