Improve Polymer Properties with
Advanced technologies call for materials with exceptional properties.
However, developing a new polymer can be time-consuming, and settling for an
existing, over-engineered material can be expensive. Grafting is faster than
developing a new material and it yields copolymers that offer specific
performance improvements or additional properties for targeted applications.
Importantly, grafted compounds act like crosslinked materials, but can be
re-melted and re-shaped.
In PP, Dow Corning's patented grafting technology acts as a knot
between polymer chains to form branches. This modified PP can enable
crosslinking in injection-molded parts to improve high temperature resistance,
boost tensile and flexural strength and increase heat-aging performance. Our
technology also offers the potential to replace reinforced PA and PET with
cost-effective, lower-density PP composites.
Solving Your Processing
In demanding automotive under-hood electrical, cooling, transmission and
engine applications, using Dow Corning's grafting technology to enhance
composites based on PP resins is a promising and economically viable approach
for reducing weight to raise fuel efficiency and lower emissions.
Our silane grafting technology offers these additional benefits:
Improves HDT and mechanical properties by approximately 20%
Offers cost reduction potential of 30% to 35% by replacing PA with PP
Combines crosslinked behavior with thermoplastic capabilities
Enables over-engineered materials to be replaced with cost-effective
