Teralink™S (sliding grade)

Teralink™ is a thermoplastic engineering plastic material that is cross-linked by irradiating electron beams onto molded components. Characterized by low abrasion loss, a low friction coefficient, and high fatigue strength, Teralink™S (sliding grade) ensures a longer service life than commercially available nylon and POM, and helps reduce the face width in design, thereby achieving reduction in space.

Features
  • Teralink™S is characterized by low abrasion loss, a low friction coefficient, and high sliding performance.

  • Due to the high fatigue strength, this material achieves a longer service life than commercially available materials.

  • The face width can be reduced by 15%–40% compared with nylon 66.

Main applications
  • Sliding parts including gears, washers, and sliders

FEX™ (cross-linked fluoroplastics)

FEX™ (cross-linked fluoroplastics) is characterized by significant improvement in abrasion durability and adhesion with base materials, while retaining a low friction coefficient. The fluoroplastics are cross-linked by irradiating electron beams. Sumitomo Electric has been developing FEX™-coated products and other application products, which are expected to reduce torque and increase durability, heat resistance, wear resistance, weather resistance, mold releasability.

Ganpla™ (parts material)

Ganpla™ is an engineered plastic material in which lubricant components are uniformly distributed. Due to the low abrasion coefficient and high wear resistance, Ganpla™ is widely used as a sliding material for automotive bearings and sliders, etc.

Four features of Ganpla™
  • Ganpla™ has superb friction characteristics in high-load friction. Unlike conventional materials, Ganpla™ can be applied to sliding parts.

  • The added lubricant components are independently distributed in proximity to one another. Unlike oil-impregnated sintered metals, internal lubricant is not consumed due to the pumping effect. The lubrication effect lasts over a long period of time.

  • The added lubricant components do not vaporize even at high temperatures, helping retain the heat resistance of the base resin. The surface of molded components is dry, ensuring easy handling.

  • Ganpla™ enables molding at almost at the same conditions as those for the base resin by using ordinary molding machines.

  • In the case of injection molding, a small amount of lubricant bleeds to the mold surface in the molding process, helping increase mold releasability and eliminating the need for draft angles.
