®FPC, Graphite & Foam Process Films
Process-film families matched to fragile FPC, graphite and foam surfaces through transfer, thermal processing, die cutting, waste removal, shipment and final release. Different roles require different grades; one generic protective film cannot cover every step.
What the material stack contains.
Read the layers in functional order; the exact construction remains grade-specific.
- 01PET carrier
- 02Application-specific acrylic or silicone PSA
- 03Optional release liner
- 04Optional antistatic or pre-shrunk variant
Named grades for technical selection.
Each ECLEAR model identifies a distinct material role and construction. Manufacturing cross-references remain controlled in the ECLEAR product master for traceability.
Adhesion is tuned to the surface and to the removal event.
01FPC, graphite and foam present different mechanical risks. Thin graphite can fracture or delaminate, flexible circuits can warp or suffer copper and coverlay damage, and cellular foam can stretch or tear when a film is removed.
02A process film therefore has a defined job: transfer, high-temperature support, die-cut carrier, waste pickup, shipment protection or temporary surface cover. Similar-looking PET films are not interchangeable when the dwell, heat exposure or removal angle changes.
03Surface roughness, porosity and cohesive strength determine the safe adhesion window. Antistatic or high-temperature variants are separate controlled grades, not universal properties of the entire family.
Performance framed around the application.
Benefits are evaluated on the intended substrate, process and finished assembly.
Coordinated films for transfer, thermal processing, converting and shipment
Controlled adhesion for smooth, matte, porous or fragile surfaces
High-temperature and antistatic variants by controlled grade
Clear removal-point definition for process traceability
From material definition to a qualified production stack.
Qualification links the material, converting route and customer production line.
Transfer, heat, die cutting, shipment or temporary cover.
Record smooth/matte face, porosity, roughness and cohesive strength.
Use the full time-temperature, pressure, chemical and dwell profile.
Check residue, damage, deformation, static and surface imprint.
Evidence to collect before specification release.
Use representative substrates, process conditions and aging sequences.
- Peel window on the exact smooth, matte or porous surface
- Thermal shrinkage and PSA creep through the complete process profile
- Graphite fracture, FPC delamination and foam deformation after removal
- Surface residue, ionic cleanliness and optical/cosmetic imprint
- Static generation and dissipation where ESD control is required
Values require a method and an approved revision.
Typical values support selection; controlled specifications come from the approved TDS.
Typical values are not specifications. Final limits are subject to the approved ECLEAR TDS and customer validation.
Questions engineers ask before a line trial.
Resolve the material role, interfaces and process window before sampling.
Why are graphite grades separated by surface face?+
Smooth and matte graphite surfaces can present different roughness, particle and adhesion behavior. A grade qualified on one face should not be assumed equivalent on the other.
Is every EC-HT film suitable for the same temperature?+
No. Time and temperature are grade-specific. Historical family data must not be converted into a blanket temperature guarantee.
Can ECLEAR recommend a grade from an application description alone?+
A first shortlist is possible, but a production recommendation requires the substrate, layer construction, equipment, process sequence, test method and acceptance criteria. ECLEAR normally moves from requirement definition to laboratory matching, samples, line trial and a frozen approved specification.
Are the values shown on this page guaranteed specifications?+
No. Website values and constructions are selection guidance. Guaranteed limits, test conditions, packaging and shelf life are controlled only by the latest ECLEAR-approved TDS, quality agreement and customer qualification record.
Where this platform is evaluated.
Each application still requires stack-level compatibility and line validation.
Parameters to control.
Record the complete process window, not only one nominal setting.
- Define substrate face, roughness, porosity and contamination limits.
- Document lamination pressure, dwell, temperature and removal angle.
- Use the complete thermal profile, not only peak temperature.
- Validate residue, static, deformation and surface imprint after removal.
What we need to know.
These inputs allow ECLEAR to narrow the grade and validation plan.
- Q1Which exact process step does the film serve?
- Q2What are the substrate surface and thickness tolerances?
- Q3What temperature, dwell and chemical exposure occur?
- Q4When and how is the film removed?
What a disciplined trial should expose early.
Early failure checks reduce scale-up risk and prevent false material comparisons.
Using a shipment film as a high-temperature carrier
Graphite delamination or fracture during stripping
Foam tearing or stretching from excessive tack
Residue, static charge or surface print-through
