GENERAL DESCRIPTION

click to resize photo Victrex plc and PBI Performance Products have introduced a new T-Series family of products, a range of proprietary polymer blends featuring PEEK (PolyEtherEtherKetone) and PolyBenzImidazole (PBI). This innovative new product series is designed to perform in the most demanding applications requiring high thermal, strength, and wear resistance.

Comprised of four grades, TU-60, TL-60, TF-60V, and TF-60C, the new T-Series products expand the current mechanical and tribological capability of existing products with enhanced stiffness, wear, hardness, and temperature performance that are made possible with the blending of PEEK (polyetheretherketone) polymer and Celazole PBI. T-Series polymers are a great replacement for metals and non-melt-processable high-temperature plastics.


T-SERIES PROPERTIES

High Temperature Resistance
T-Series polymers are the most thermally stable thermoplastics on the market, offering excellent mechanical performance at high temperatures up to 300°C (572°F). This semi-crystalline material retains mechanical properties well above the polymer’s glass transition temperature. T-Series polymers are currently the highest performing melt processable thermoplastics for use in applications requiring physical property retention and wear resistance at elevated temperatures. They are a great replacement option for metals and non-melt processable high temperature plastics (i.e., polyimides).

Excellent Tribology
T-Series PEEK-PBI polymers are inherently lubricious with a very smooth surface finish. They are low sloughing and offer exceptional abrasion resistance.

Environmental Resistance Ratings
In high temperature exposure to organic chemicals, molded parts made with T-Series PEEK-PBI polymers offer outstanding chemical resistance and property retention, even after extended exposures. They have excellent resistance to a range of extreme environments that degrade most plastics.

Other properties
• Excellent wear and strength at high temperatures for long-lasting components • Excellent thermal insulator (does not melt) • Excellent hardness (25% increase in Rockwell A Scale) • Creep resistant (up to 30% better than other PEEK materials) • Increased design and processing flexibility • Superior chemical resistance versus metals and other high performance polymers • High purity and does not outgas • Naturally opaque


EXAMPLE APPLICATIONS

• Plasmas torches • Conveyor belting, tilt pad bearings • Glass handling • Pumps • Turbines • Compressors • Seals • Seats • Thrust washers • Bushings • Bearing cages • Balls • Electrical insulators • Soldering tools • Wafer transportation and chamber parts in spin coating, etching, PVD • Lifting pins, screws, bushings • Cassettes • End-Effector pads • Lamp holders


T-SERIES GRADES

These T-Series PEEK-PBI grades are available in limited quantities of machinable pre-molded sheet and rod forms ONLY from Boedeker Plastics:

TU-60
Unfilled, unreinforced (neat) PEEK-PBI blend suitable for high performance in high-temperature and high-strength applications.

TL-60
Lubricant filled PEEK-PBI blend designed to reduce friction and wear in bearing and sliding applications.

TF-60V
Glass reinforced PEEK-PBI polymer blend for even greater rigidity and dimensional stability while maintaining many of the useful characteristics of the unfilled grade. The glass reinforcement yields a product with an exceptional strength-to-weight ratio and increased tensile strength.

TF-60C
Carbon reinforced PEEK-PBI polymer blend for highest strength, stiffness and dimensional stability while maintaining many of the useful characteristics of the unfilled grade.
