Polymer structure influences behaviour without setting a complete rating
- Cross-linking
Connections between chains create a network. The actual cure, formulation and environment determine the resulting material response.
- Crystallinity
Ordered regions differ from disordered chain arrangements. Crystallinity describes a structure, not a universal performance advantage.
- Plasticizer / plasticization
The added molecules alter the formulation’s mobility and response. Compatibility and possible migration require the actual material data.
- Glass-fiber reinforcement
Reinforcing fibres sit within the polymer matrix. Fibre content and orientation affect strength, processing and dimensional response.
- Polyethylene (PE) / XLPE
PE and cross-linked PE have different network structures. The cable material designation must be read with its actual compounded grade and specification.
- AnisotropyThis term
Material response can differ with direction. Match the test direction and loading direction when comparing specifications.
Links between chains, ordered regions, additives and fibre orientation alter a polymer’s response. Their effect depends on the actual formulation and processing.
