Interface Connect (IC®) builds a strong, durable interphase between polymer (PTFE) and engineered fillers. Below are our two core IC®-Mica/PTFE and IC®-Graphite/PTFE, with typical characteristics, advantages, and where they shine.

IC®-mica/PTFE composite

IC-Mica/PTFE is your go-to when dimensional control, stiffness, and wear resistance matter most. IC strengthens the polymer–filler interphase so mica truly reinforces PTFE rather than just “sitting” in the matrix.

Key advantages:

  1. Higher stiffness and reduced creep

  2. Lower wear rate and broad chemical resistance of PTFE

  3. Lower shrinkage for tight tolerances

Properties (standard):

  1. Density: 2.11 g/cm³

  2. Hardness (Shore D): 67

  3. Shrinkage: 0.4%

  4. Tensile modulus (ASTM D638): 428 ksi (≈ 2.95 GPa)

  5. Wear rate (JIS K 7218): 1.336 × 10⁻⁷ mm³/(N·m)

Six cylindrical engine bearing shells with a copper-colored exterior and black interior, arranged on a white surface.

Typical applications :

Valve seats and stem/rod seals requiring dimension hold across temperature/pressure; Gaskets and pump components for chemical service; Guide rings/wear elements where stability > maximum lubricity; Precision parts in instrumentation/analytical where drift must be minimized

IC®-graphite/PTFE composite

IC-Graphite/PTFE prioritizes low friction. With IC, the interface carries load and moves heat more effectively, supporting longer life in dry or marginally lubricated service.

Key advantages:

  1. Low coefficient of friction; excellent dry/wet sliding behavior

  2. Effective heat dissipation via graphite network

  3. Broad chemical compatibility

Properties (standard):

  1. Density: 2.07 g/cm³

  2. Hardness (Shore D): 63

  3. Shrinkage: 1.08%

  4. Tensile modulus (ASTM D638): 329 ksi (≈ 2.26 GPa)

  5. Wear rate (JIS K 7218): 4.895 × 10⁻⁷ mm³/(N·m)

Typical applications :
