Leading High Heat-resistant Polymers Vie for a Spot in the Top 10

SpecialChem / Mar 30, 2011

To offer smarter answers to application and processing issues in state-of-the-art industries as well as mass production markets such as aerospace, automotive or electronics, new polymer versions are based on more or less well-known specialty high heat polymers such as PBI, Polyimides and derivatives for instance melt processable TPIs or Polyamide-imides (PAI); PEEK (polyetheretherketone), Polybenzoxazole (PBO), some Liquid Crystal Polymers (LCP), Polyphenylene sulfide (PPS), alloys of PBI and PEEK or TPI and PEEK, Perfluorinated polymers (PTFE, PFA), silicones, special versions of Epoxies, Polysulfones, Polycyanates etc.

Some specialty polymers offer peak or long term thermal resistance exceeding 250°C, excellent mechanical strength and toughness, dimensional stability, low outgassing, resistance to hydraulic, automotive, and industrial fluids and solvents; low coefficient of thermal expansion, creep resistance, and into the bargain electrical property stability, flame retardancy, radiation resistance.

These outperforming polymers are excellent replacements for metals, ceramics, and others allowing to manufacture parts as diversified as thrust washers and oil seal rings for automotive and off road vehicle transmissions, thermal insulators and stripper fingers for high-speed copiers, jet engine components, check valve balls, spline couplings, heat-resistant gears, vanes, wear strips, and valve seats, carriers for aluminium hard disks and silicon wafers, journal bearings, and bearing retains, electronics components, super fibres for bullet-proof fabrics, shields, helmets or micro-asteroid shields etc.

Many chemical entities have been developed for special applications such as, for example Hyflon® MFA resins, Ultrason® E Dimension and...
