Torlon 5060 introduction
Torlon 5060 Thermoplastic for Extreme Temperatures
Drake Plastics Ltd. Co. introduced a new high strength, insulative material based on Torlon® PAI. Drake PAI 5060 is a highly loaded composite with 60% fiber reinforcement.
Prior to the introduction of Drake PAI 5060, the maximum reinforcement available in PAI was 30 percent.
Drake PAI 5060’s balance of extremely high modulus (stiffness), minimal CLTE (dimensional change with temperature) and machinability make it an excellent upgrade to difficult to fabricate high-performance polymers or ceramics.
Tensile tests confirm the modulus is more than 50% higher than glass reinforced PEEK, while the thermal expansion is reduced to the range of steel.
Drake’s proprietary extrusion process was key to commercializing this material. The high reinforcement makes injection molding of 5060 impossible with conventional technologies. Len Wojtaszczyk, Injection Molding Manager summed it up by saying “molding this material is like trying to form granite - it can be done but takes lots of temperature and lots of pressure.” Drake’s unique injection molding capabilities have overcome the challenges of this highly reinforced PAI polymer and molded parts are also available.
Machined specimens from Drake 102 mm extruded stock yield the following properties:
Ø 102 mm Rod
Ø 102 mm Rod
|30% GF PEEK|
|Tensile Strength||185 MPa||201 MPa||129 MPa|
|Elongation at break||1.8%||3.7%||3.2%|
|Tensile Modulus||16.1 GPa||10.0 GPa||9.3 GPa|
|Flexural Strength||251 MPa||277 MPa||205 MPa|
|Flexural Modulus||13.9 GPa||8.6 GPa||6.6 GPa|
The most amazing characteristic of this material is its strength retention and creep resistance at elevated temperature. The compressive modulus is two times that of Torlon 5030 and the compressive strength is 1.5 times higher. There is no thermoplastic that offers better performance than PAI and this new material surpasses Carbon Fiber reinforced Torlon 7130, the strongest of the commercial Torlon grades. According to Gary Brooks, Drake’s Chief Technology Officer, ordinary non-reinforced PAI is stronger and stiffer at 200°C than PEEK is at room temperature. Drake PAI 5060 increases this difference while offering lower thermal expansion compared to all other reinforced thermoplastic polymers. Interest in this polymer has been great within the aerospace, semiconductor and oil and gas industries due to its strength, toughness and machinability. Investigations are under way in ultra-high voltage applications as well.
Rod is available in 12.7 mm up to 102 mm diameter and plate is available up to 44 mm thick on a made-to-order (MTO) basis. Drake makes samples of stock sizes available for qualified customers and applications.
