Engineering selection
Data your engineering team can specify
We define the finished part around the selected material grade, test basis, drawing and assembly conditions. The items below can be included in the project review and data package.
Typical screening rangeCustomizable by FLEXCENDGrade-specific data availableAssembly validation required
Data pointWhat FLEXCEND can define or provide
Graphite layer thicknessRepresentative standard window: 0.070–0.100 mm; other thin grades reviewed to drawing
In-plane thermal conductivityRepresentative selected-grade range: 700–1,000 W/m·K, with direction and test basis identified
Graphite densityApproximately 0.85–1.21 g/cm³ across the reference thickness range
Heat resistanceGraphite-only reference up to 400°C; adhesive, PET/PI film and edge treatment usually set a lower stack limit
Electrical behaviorConductive material; reference electrical conductivity about 10,000 S/cm, so isolation is added where required
GeometryCustom die-cut outlines, openings, alignment features and laminated isolation zones
In-plane / through-plane dataThermal data can be supplied for the selected grade with direction, thickness and test basis identified
Thermal resistance / stack-upReviewed across graphite, adhesive, protective film, insulation layer and contact interfaces
Density and finished part massCalculated after the material grade, laminated construction and die-cut geometry are fixed
Operating temperatureConfirmed for the complete laminated construction rather than the graphite layer alone
Bend and handling limitsReviewed against bend radius, cut direction, narrow webs, openings and the customer assembly method
Material complianceRoHS, REACH, halogen or flame documentation matched to the selected grade when available
How to read these values: Published ranges are representative design-screening windows across material families FLEXCEND can source, convert and evaluate. They are not one universal finished-part specification. Final values are confirmed against the exact grade, thickness, adhesive stack, test method, approved drawing, production lot and complete customer assembly.
Representative sample

This image was extracted from the supplied product library and shows a representative part family. Exact material, grade, thickness and dimensions are defined by the approved drawing and material specification.
Engineering evidence
A project data package—not a generic material claim.
The exact content is agreed by program. Performance values stay linked to the selected material, thickness, method and test condition.
Performance evidence
Supplier TDS or relevant test data tied to the selected grade, thickness, method and test condition
Dimensional control
Critical dimensions and tolerances reviewed against material behavior, part geometry, tooling and process route
Prototype / first article
Fit samples, comparison sets and dimensional reporting can be agreed before production release
Compliance documents
RoHS, REACH, halogen, flammability or other declarations supplied only when supported by the exact selected material
Traceability and delivery
Drawing revision, material or production lot, inspection plan, liner format, kitting and packaging defined by program
Made to drawing
Configure the complete part—not just the base material.
We review how material, adhesive, liner, lamination, geometry and delivery format work together at assembly.
- Protective film lamination
- PET or PI isolation layer
- Adhesive zones
- Pull tabs and liners
- Complex die-cut geometry
- Prototype and production tooling
Fast technical response
Send the inputs engineers use to make a real selection
A drawing plus these operating conditions lets us recommend a practical construction instead of a generic material.
- Heat-source location and power
- Available spreading area and heat destination
- Maximum part thickness and weight target
- Need for adhesive or electrical isolation
- Bend, fold or repeated-flex requirement
- 2D drawing, prototype quantity and annual volume
Engineering boundary
Thermal performance depends on grade, spreading area, contact interfaces and assembly design. Final selection is validated around the customer’s heat path.
