Functional masterbatches

Modifying polymers through the use of additives makes it possible to create specialized blends and individualized plastics with improved processability, appearance and properties. Granula Group custom formulates functional additive masterbatches with specific performance properties to meet our customers’ every application requirement.

What are combination colour masterbatches?

Combination colour masterbatches are ready-to-use plastic concentrates in granular form. They combine colours and functional additives within a single carrier polymer. This enables plastics to be coloured in one step while simultaneously imparting properties such as as laser marking, UV protection, flame retardancy, antistatic performance, antiblocking or lubricity.

Advantages for plastics processors

  • Simplified processes - colour + additive in a single masterbatch
  • Cost efficiency - reduced handling and sotrage requirements
  • Enhanced safety - fewer dosing errors, greater production stability
  • Consistent quality - uniform distribution of colours and additives
  • Flexibility - functions precisely tailored ot the final product

Typical additive functions in combination masterbatches

Combination masterbatches may include: 

  • UV stabilisers/antioxidants - protection against light ageing, oxidation
  • Antistatic/conductive agents - reduction of static charge
  • Flame retardants - delayed flammability
  • Lubricants / anti-blocking agents - easier processing, non-stick performance
  • Biocides / antimicrobial additives - hygiene protection
  • Barrier additives - enhanced resistance to oxygen or moisture
  • Impact modifiers - improved crack and fracture resistance
  • Effect pigments - metallic, pearlescent, glossy or matt  finisehes

Applications

Typical fields of application include:

  • Packaging films - food contact, UV protection
  • Household products - antistatic, antimicrobial, hygienic properties
  • Electronics housings - flame retardant or antistatic performance
  • Garden and construction products - UV-stable, wather-resistant

Our masterbatch formulations optimise processing in production and safeguard polymers against harmful environmental influences such as UV light, oxidation, and high temperatures. Tailor-made additive systems prevent discolouration and the loss of essential mechanical and physical properties. Granula® masterbatches deliver tangible added value both both during processing and troughout de product's service life.

We also design and produce combination masterbatches with pigments, additives, processing aids or antioxidants specially engineered for temperature or abrasion-sensitive polymer blends.

Compliance and safety

Granula AG develops customised combination masterbatches precisely tailored to product requirements. Compliance with EU, FDA, MDR, PPWR, and REACH regulations is always ensured – providing tested safety and reliable certification.
