It also helps improve the adhesion properties of PVB resin. Thus, ensuring that it bonds effectively with various substrates. The careful selection and dosage of the plasticizer ensure that the filament has optimum performance in 3D printing processes.
Blending with Thermoplastic Polymers
PVB filaments are usually blended with other thermoplastic polymers in some cases. This is done to enhance their mechanical properties. Polymers such as Acrylonitrile Butadiene Styrene and Polycarbonate are common choices. These polymers improve the filament's toughness, creating a more balanced material that holds impact resistance and rigidity in equal measure. This blending process involves heating the PVB resin and the chosen polymer together until they are fully fused. The result is a homogeneous mixture that is extruded into filament strands.
Incorporation of Stabilizers and Additives
To improve the functionality of PVB filaments, manufacturers usually add UV stabilizers, antioxidants, and colorants. UV stabilizers like benzotriaazole are critical in preventing the degradation of PVB resin when exposed to UV light. This is especially useful in outdoor applications. Antioxidants such as hindered amine light stabilizers are incorporated to prevent oxidation. It avoids the resultant material's deterioration over time. Finally, additives like carbon black or titanium dioxide are added not only to give color but also improve the UV stability further.
