Flow polymers
WebFlow Rate Ratio (FRR) is commonly used as an indication of the way in which the rheological behaviour of a thermoplastic is influenced by the molecular mass distribution of the material. Since polymers are made up of varying lengths of polymer molecular chains, the length of the chain determines the flow characteristics.
