Complex Masterbatches
Our design rules for formulations
As in all well-done things, the best result is obtained if there is “teamwork”. Rifra translates this motto into a preference for solutions that combine color formulation with the most high-performance chemistries, providing “all-in-one” additive structures directly in the plant. We mention some of the most common solutions, emphasizing that it is, in principle, always possible to create a complex by combining the desired color with the active ingredients necessary to make the process more efficient and enhance the qualities required of the finished product.
| Rifra solutions | Synergistic advantage | Guaranteed efficiency |
|---|---|---|
| RIFRACHEM CX NUCLEANTE | Color guides the crystallization of semi-crystalline polymers: pigments act as heterogeneous nucleation sites, while the nucleating additive optimizes crystal growth. Together they create a fine and homogeneous structure that enhances color depth and boosts mechanical resistance. | The synergy guarantees intrinsic dimensional stability and faster cycles: it reduces the thermal gradient and internal stresses, minimizing warpage on complex geometries and cutting cycle times with more efficient cooling. |
| RIFRACHEM CX AOX | The antioxidant selectively protects the polymer’s chemical bonds from oxidative stress during thermal transformation, ensuring that pigments and dyes develop a pure and repeatable shade without risks of “shade shift” or yellowing of the carrier that would alter the compound’s base color. | The stabilized system offers tolerance to extreme process conditions, allowing high temperatures and waste reuse without chromatic degradation, maximizing production yield and operational flexibility in molding cycles. |
| RIFRACHEM CX SLIP | Slip molecules migrate to the surface, forming a lubricating layer that preserves the perceived shade. The result is a colored part with a low-friction surface, ideal for moving components or fluid joints without chromatic alterations. | Smoother extraction from the mold, reducing mechanical stress on the part. The decrease in friction minimizes internal stresses, warpage, and surface scratches on the newly consolidated colored area, optimizing quality and production yield. |
| RIFRACHEM CX ANTIBLOCK | Antiblocking particles, homogeneously dispersed in the coloring system, generate a controlled micro-roughness on the part’s surface. This ensures optimal release from the mold without affecting color brilliance, preserving its intensity and aesthetic uniformity. | Drastic reduction of release sprays and defects from imperfect release. Variable opacification and spray halos are eliminated, guaranteeing a uniform and repeatable surface finish batch after batch in continuous production. |
| RIFRACHEM CX PPA | The process aid (PPA) eliminates flow instabilities that generate aesthetic defects and distort the chromatic perception of the molded part. The synergy guarantees a smooth and uniform surface, enhancing color depth and homogeneity in high-precision applications. | Optimal mold filling with reduced injection pressure. PPA facilitates flow in thin walls and complex geometries, distributing color uniformly across the entire surface and minimizing production waste. |
| RIFRACHEM CX UV | An integrated protection system for polymers: UV stabilizers selectively shield the harmful wavelengths that degrade the polymer. In CX UV formulations, selected pigments and active ingredients resist external aggression, maximizing color tone retention and performance for the entire life of the product. | Pre-determined and certifiable durability in critical applications. UV protection, homogeneously dispersed at the molecular level in the coloring system, permeates the entire mass, allowing for the design and validation of the product’s useful life in terms of aesthetic and mechanical performance. |
