What is Plastic PEEK Material

Plastic PEEK material, with its excellent heat resistance, wear resistance, and dimensional stability, is an ideal material choice for automotive hood and underhood structural components.

LNP™ LUBRICOMP™ LGL33 (PDX-L-90086), produced by SABIC, is a composite modified PEEK material (PEEK-CD15-PTFE15). By adding 15% graphite and 15% PTFE, its stability and life in high-temperature friction environments are significantly improved.

In automotive underhood systems, LGL33 can be used to replace traditional metal or unfilled PEEK components, reducing vehicle weight while improving wear resistance and noise performance, meeting the demanding operating conditions of the underhood.

01 | Material Highlights

Outstanding wear resistance

  ・Containing 15% graphite and 15% PTFE, the material forms a self-lubricating system internally, significantly reducing wear under repeated friction or sliding conditions.

Stable coefficient of friction

  ・The static friction coefficient is 0.39 and the dynamic friction coefficient is 0.36 (ASTM D3702), maintaining smooth operation in a continuous friction environment.

Good mechanical strength

  ・The tensile strength reaches 65 MPa, and the flexural modulus exceeds 4300 MPa. It can maintain structural integrity even after long-term use.

Excellent heat resistance

  ・The heat distortion temperature can reach up to 298°C (ASTM D648, 0.45MPa), and it can withstand the high-temperature environment in the engine compartment of automobiles.

Stable in size and low water absorption rate

  ・The water absorption rate is only 0.03%, maintaining precise fit and reliable performance even under changes in humidity.

02 | Processing and Technology Compatibility

LNP™ LUBRICOMP™ LGL33 is specifically designed for injection molding applications.

  ・Flow characteristic balance: The modified filler structure ensures uniform distribution of the material during the molten flow process, reducing warpage and internal stress.

  ・Low shrinkage rate: The shrinkage rate is 1.3% in the flow direction and 1.5% in the vertical direction, ensuring precise product dimensions.

  ・Suggested mold temperature: It is recommended to control it between 170 and 190°C to balance surface quality and crystallinity.

It is suitable for structural components, wear-resistant parts and moving components with extremely high requirements for dimensional accuracy.

03 | Typical Applications

Automobile hood and engine compartment components

  ・It has both heat resistance and wear resistance, and can replace metal parts to reduce weight and cost.

Compressor and pump body assembly

  ・It exhibits stable wear resistance under dry friction or boundary lubrication conditions, thereby extending the service life of equipment.

Mechanical bushings, gears, sliders

  ・It has excellent silent effect and low wear characteristics, making it suitable for industrial equipment that operates continuously.
