Filler Masterbatches

 
Corbi offers mineral-filled compounds, based on PE/PP/PS, that contain Caco3, talk, Baso2 and others. Depending on the application, they can impart properties to film and molded articles that include increased stiffness or a paper-like appearance. Other advantages may include increased efficiencies through more rapid cooling of the film bubble and reduced energy consumption during processing. These masterbatches typically contain 30-80% mineral content in a polymer carrier. Corbi filler masterbatches offer a convenient way of incorporating Caco3 and other minerals in thermoplastics, without contamination by dust. They have perfect dispersion and optimized flow properties, ensuring easy processing. Filler masterbatches are used in injection, Blow-moulding, Film, Sheet and Tapes applications.
 
They offer the following advantages:
 
flashInjection & blow-moulding
 - Lower raw materials cost, as they are usually more economic than polymer resins.
 - Increased output due to faster mould cooling.
 - Reduction of  colour masterbatch requirement.
 - Higher resistance to heat deflection, higher rigidity and stiffness.
 - Improved dimensional stability, weldability and printability. 
Addition rate of FILLER masterbatches in injection & blow-moulding applications can  be up to 50 %, however, most usual levels are between 5-30 %. 
 
flashFilm, sheet, sacks, bags
 - Lower raw materials cost, as they are usually more economic than polymer resins.
 - Reduction of  colour masterbatch requirement.
 - Higher stiffness, paper-like effect.
 - Improved weldability and printability.
 - Improved anti-blocking properties 
 - Better bubble stability. 
Addition rate of FILLER masterbatches in film applications is 2-80 %. 
 
flashPE & PP tapes
- Anti-fibrillation (also known as anti-splitting) 
- Lower raw materials cost, as they are usually more economic than polymer resins.
- Reduction of  colour masterbatch requirement.
- Higher stiffness.
- Improved weldability and printability.
- Improved anti-blocking properties.
- Improved weaving ability.
- Easier processing 
Usual addition rate of FILLER masterbatches in tapes is 3-8 %.
