Application-led compound development
HFFR formulation is a balance between the polymer matrix, mineral flame retardant, interfacial compatibility and processing package. Nova Polymer helps you define this balance around the cable layer and intended application, with separate targets for material properties and finished-cable performance.
Technical focus areas
- Polymer blend selection and mineral filler loading
- Dispersion, interfacial adhesion and retained elongation
- Extrusion pressure, surface quality and output stability
- Smoke, acidity and flame-test requirements appropriate to the cable design
From formulation brief to validation plan
Begin with the intended cable layer, construction and operating environment. Define the target properties and relevant test methods before comparing formulations. Review compound behaviour under representative extrusion and, where applicable, crosslinking conditions.
Material screening, production trials and finished-cable qualification provide complementary evidence. The applicable specification and acceptance criteria should be agreed for the specific project.
