Dow Corning siloxane masterbatches can improve the scratch and mar resistance of
thermoplastics, especially polyolefins.
Automotive designers use Dow Corning siloxane masterbatches for applications
such as:
-
Instrument panels
-
Central consoles
-
Pillars
-
Partially painted bumpers
-
Fascias
Polypropylene compounds, in particular, have become the materials of choice
for many of these applications. Polypropylene is widely used, for example, in
hard automotive interiors or covers such as door trim panels. Softer
TPOs, polypropylene-based thermoplastic materials, with a high rubber content
(>20%), are popular for parts such as airbag doors. The
reasons for increased use of these compounds include:
-
Recyclability
-
Long-term durability
-
Safety regulations
-
Cost requirements
