Ceville has full traceability of all raw materials and pellets sold. We are also developing tracing and authentication procedures with our partners for recycled contents and their let-down ratios.
UL-2809 Ocean Bound Plastic
In our laboratory, our quality assurance teams inspect both the raw material and finished goods to ensure that every granule meets our high standards. We only use 100% clear flakes to ensure the best quality for our pellets. In addition, we perform the following checks:
For raw materials: moisture content, aged flakes, color, density
For finished product: IV, melting point (DSC), TiO2 content, powder content, ash content, iron content, DEG content, moisture content
SSP System for Controlling the Intrinsic Viscosity (IV)
Ceville’s dedicated Solid State Polycondensation (SSP) system is able to increase the intrinsic viscosity (IV) of the RPET pellets to between 0.8-1.1 dl/g, which is the same as virgin PET pellets.
