 Industry Application - IV Builder |
For rPET, the IV level can vary depending on the source of the recycled material and the recycling process used. Generally, as a result, rPET tends to have a lower Intrinsic Viscosity than virgin PET. During the recycling process, polymer chains can be broken, leading to a reduction in molecular weight.
When higher mechanical properties are required for specific applications, these additives can provide valuable assistance. ColorWay's IV Builder function as chain extenders, elevating molecular weight and improving the mechanical characteristics of rPET accordingly.
