Enhanced Performance at High Temperatures
Thermec™ is a new entry in the DOMO EP product portfolio. Developed to meet demanding applications requiring higher heat resistance and performance at elevated temperatures, the Thermec™ product range is formulated with different high temperature base polymers depending on the specific application requirements. The growing list of available grades delivers a wide range of properties depending on the type and concentration of the reinforcing agents (glass fibres, minerals, etc.) stabilizers and processing aids.
Thermec™ N - Polyphthalamide (PPA) compounds
Based on several different PPA base polymer types, the Thermec™ N family offers an extensive portfolio of semi-crystalline thermoplastic compounds for use in both oil and water heated molds. These compounds offer a unique combination of strength, temperature, wear and chemical resistance. The most common grades are 30% and 35% glass fibre reinforced compounds. The mechanical properties of Thermec™ N surpass those of standard PA6 and PA6.6 polyamides at application temperatures up to 230°C – ideal for metal replacement.
- High melting point
- Continuous service temperature up to 230°C
- Low moisture absorption
- Good chemical resistance
- Good fuel resistance
- Good creep resistance
Thermec™ N (PPA)
The new Thermec™ N is characterized by high heat resistance, good chemical resistance and high mechanical rigidity. It is suitable for applications involving higher heat exposure like smaller-sized vehicles, where tighter under-hood packaging, reduced air flow, and hotter environments require higher performing materials.
Thermec™ S (PPS)
The high mechanical properties and low water absorption makes this material suitable for use in many applications including automotive, E&E, gears and outdoor power equipment. Thermec™ S is renowned for its excellent thermal properties and heat resistance. It also offers a great blend of mechanical and electrical properties, resistance to wear, moisture and chemicals. Further, it is naturally flame retardant. Thanks to its outstanding flow properties, Thermec™ S delivers commercial benefits through reduced cycle time and increased design freedom.
Thermec™ K (PEEK)
Because of its robust nature, Thermec™ K is used to fabricate items in highly demanding applications, including bushings, bearings, piston parts, pumps, air compressors, compressor plate valves, cable insulation and textile machine thrust pads. It is one of the few plastics capable of withstanding ultra-high vacuum applications. It is extensively used in the aerospace, automotive, food and chemical processing industries.
Thermec™ S - Polyphenylene Sulfide (PPS) compounds
PPS is a high performance thermoplastic that provides unmatched value in demanding applications where superior heat resistance, design stiffness, wear & friction and process flow qualities are required. With no known solvent below 200°C, PPS outperforms PA6, PA6.6 and PPA in most difficult environments, including exposure to steam and harsh chemicals. This makes PPS compounds ideal for water pump impellers and energy exploration and production applications. Thermec™ PPS compounds also have the ability to be molded, extruded, or machined to extremely tight tolerances for more precise forming of detailed designs that cannot be matched even by the substitution of metal or cast iron. The Thermec™ S product range offers a wide variety of reinforcing options with differing filler content, including glass fibre, glass bead and mineral.
- Excellent thermal stability
- Superb chemical resistance
- Outstanding dimensional stability
- Inherently flame retardant
- Stable electrical properties
Thermec™ K – Polyetheretherketone (PEEK) Compounds
PEEK is a semi-crystalline thermoplastic with excellent mechanical properties and chemical resistance that are retained even at high temperatures. It is the most thermally stable thermoplastic currently on the market. It has a glass transition temperature of around 143 °C and a melting point of about 343 °C.
A combination of high stiffness and low density makes PEEK polymer-based compounds ideal for innovative designs requiring structural performance and weight reduction at elevated temperatures.
It is wear resistant, inherent flame retardant and is known for its very low toxicity upon combustion.
The Thermec™ K product range offers a variety of different products developed for specific application needs. The most prevalent grades of this line are glass fiber and carbon fiber reinforced products.
Exceptional properties at elevated temperatures:
- Chemical resistance
- Mechanical strength
- Wear/abrasion resistance
- Fatigue resistance
- Dielectric strength
- Suitable for continuous-use temperatures up to 260°C.
