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
Material familyEVA, silicone foam or another reviewed cushioning grade; each family is quoted on its own data basis
ThicknessRepresentative cross-family conversion window: 0.50–25.40 mm; exact range depends on foam family and tooling
Silicone foam densityRepresentative selected-grade range: about 192–320 kg/m³
Compression force-deflectionRepresentative silicone constructions: about 20–310 kPa at their published strain and test method
Compression setRepresentative selected-grade range: about 5–30% under the stated time, strain and temperature
TemperatureSelected silicone grades may cover approximately -51 to 204°C; EVA and adhesive limits are confirmed separately
Compression force-deflectionLoad at the target strain can be compared across EVA, silicone and other candidate foams
Compression set / creepLong-term thickness recovery reviewed for temperature, dwell time and duty cycle
Density and hardnessGrade data used together with thickness and geometry rather than as the only selection criterion
Shock and vibration behaviorPrototype sets can be made for system testing under the customer’s actual mass and input
Temperature and moistureEnvironmental limits, water absorption or sealing behavior reviewed by material family
Flammability / complianceUL 94, RoHS, REACH and halogen status confirmed only for the exact selected grade
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.
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.
- Material and grade comparison
- Custom outline and openings
- Adhesive-free zones
- Pull tabs and liners
- Lamination with film or mesh
- Prototype comparison sets
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.
- Part function: spacing, cushioning, sealing or anti-rattle
- Nominal gap and tolerance stack
- Target compression and force limit
- Shock, vibration and supported mass
- Temperature, moisture and fluid exposure
- Drawing, adhesive surface and annual volume
Engineering boundary
Cushioning performance depends on installed compression, supported mass, vibration or shock input, temperature and long-term set. Candidate parts require evaluation in the complete assembly.
