Filler masterbatches are based on calcium carbonate and talc. They are used for property modification (e.g. as anti-split in PP tapes and as impact modifiers in PP) or to reduce cost and improve processing of plastic products.

Our Filler masterbatches are used in injection, blow-moulding, film, sheet and tapes applications. They offer the following advantages :

Injection & blow-moulding 

• Lower raw materials cost, as they are usually more economic than polymer resins. 
• Increased output due to faster mould cooling.
• 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 %. 

Film, sheet, sacks, bags 

• Lower raw materials cost, as they are usually more economic than polymer resins.
• 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 2-20 %. 

PE & PP tapes

• Anti fibrillation (also known as anti splitting).
• Lower raw materials cost, as they are usually more economic than polymer resins. - Reduced need of pigmentation.
• Higher final product stiffness. 
• Improved weld ability and printability. 
• Improved anti-blocking properties. 
• Improved weaving ability. 
• Easier processing. 

Usual addition rate of FILLER masterbatches in tapes is 3-8 %. 

A PE based “anti-splitting” masterbatch adds a certain elasticity to the tape, while a PP based one is more compatible with the polymer. 

PS products

• Our fillers are used to add rigidity and reduce cost of PS products. 
• Additionally some of our products contain talc and are used to improve mechanical properties of PS products while they can be also used as a nucleating agent in foamed PS sheets.
