grade-screening guide
EVA can serve as a versatile base resin in flexible cable compounds. Grade selection and formulation determine the balance between processing, filler acceptance, flexibility and final mechanical properties.
01 / ROLE OF EVA
EVA base resins for flexible cable compounds, insulation and shielding formulations.
Through formulation and compounding, EVA supports flexible cable compounds and specialty applications that require balanced processing and mechanical behavior.
FlexibilityCompound compatibilityProcessability
Flexible performance
Material softness can support bending, routing and installation demands.
Processing window
Melt behavior is selected around compounding and extrusion conditions.
02 / INFORMATION FOR GRADE SCREENING
What to include in an enquiry
A complete process description is more useful than a grade number alone.
Equipment and conditions
Conversion method, temperature profile, line speed, residence time and any known processing constraints.
Other materials in the system
Fillers, crosslinkers, tackifiers, waxes, additives, blend partners or layer construction.
Required test results
List target properties, test methods, acceptance limits and relevant service conditions.
Trial and supply information
Sample quantity, packaging preference, expected annual volume and required qualification timing.
