| CESA-conductive | While the good insulation properties of polymers are desirable in a wide range of applications, their typically very low electrical conductivity sometimes restricts their area of application. The use of CESA-conductive compounds and masterbatches improves electrical conductivity, enabling plastic parts, for example, to protect highly sensitive electronic components from damage caused by electrostatic discharge. Conductive compounds are also increasingly used in components for transporting hazardous materials. |
| CESA-IR | CESA-IR masterbatches have been developed for use in agricultural thermal films. While maintaining transparency, they allow penetration of short-wave IR radiation coming from solar rays, yet prevent the emission of longer-wave IR radiation. This increases heat retention, supports plant growth and allows greenhouses to maintain an adequate temperature, even at night. |
| CESA-dry | CESA-dry desiccant masterbatches eliminate the need for pre-drying resin before processing, and also help to protect metal tools from oxidation. They are particularly recommended in applications where high moisture levels negatively influence processability. For example, CESA-dry MB 1, a concentrate of specific active substances in a polyethylene carrier, can be used to facilitate processing of recycled resins, resins containing biodegradable starch and other high-moisture-level polymers. It is also suitable for injection and blow molded polyolefins. |
| CESA-mix | When resins and certain reinforcing materials are not compatible, the addition of an appropriate compatibilizing material may allow them to be blended or alloyed. CESA-mix compatibilizers bridge the gap between different resin chemistries, enabling them to form a homogeneous structure. |
| CESA-release | The addition of CESA-release masterbatches to polymers during processing prevents parts from sticking to the mold cavity, facilitating their removal. Other advantages include reduced cycle times and increased machine output. |
| CESA-clean | Plastics processing periodically requires complete removal of thermo-oxidized deposits from extruders and injection molding machines. CESA-clean masterbatches permit fast, economical cleaning of machinery to facilitate color or resin changes with minimal downtime and loss of virgin material. |
| CESA-extend | Re-using post-industrial or post-consumer polyester regrind has typically been limited due to the adverse effects of heat and moisture on the virgin resin . CESA-extend masterbatches utilize an oligomeric reactant to repair the damage and restore the resin's Intrinsic Viscosity (IV). Processors can then use higher proportions of recycled resin while maintaining the same processing properties as virgin PET.
A series of CESA-extend masterbatches with a variety of carrier resins is available for clear and opaque applications. These include extruded polyester sheet and strapping, stretch blow-molded PET bottles, foamed PET sheet or film and pelletizing undried recycle or scrap. |
| CESA-lux | Phosphorescent pigments are characterized by their ability to absorb and store the energy of natural or artificial light, and then emit this energy in the form of visible light in the dark. CESA-lux masterbatches enable molder to produce glow-in-the-dark extruded or molded articles. |
| CESA-bright | Often a brilliant appearance with a bluish undertone is desirable for thermoplastic articles, particularly for polymers with an inherently slightly yellow cast. Topical optical brighteners have typically been used to improve the surface whiteness of plastic articles and synthetic fibers. Adding CESA-bright concentrates to the polymer itself produces much better brightness retention over time than surface treatment with topical optical brighteners. CESA-bright masterbatches convert UV radiation into visible, bluish light, improving the long-term appearance of finished products. |
| CESA-mat | CESA-mat masterbatches contain application-specific additives to modify the surface properties of plastic products. They reduce gloss, giving as matte or frost-like effect to PET sheets and bottles, polyolefin films and a wide range of other products. They also are used to impart whiteness and opacity to plastic products, enhancing their appearance by light diffusion. Available in a number of different carriers ranging from polyolefins and styrenics to engineering resins, CESA-mat masterbatches are suitable tor use in injection and blow molding, film and sheet extrusion and other processes. |
