Additive masterbatches

Description

Additives are ingredients pivotal for polymers’ employment success. Without antioxidant additives, for example, all products made of polypropylene and polyethylene largely used both for private and industrial purposes would not be available. Other materials, such as dispersant additives and process aids, ensure polymer materials are processable so as to ease their transformation in all diverse formats.

The mechanisms that regulate degradation and stabilisation accordingly, but also rheology and processing, are strictly linked to the polymer – the basics of compound formulation. It is therefore necessary to understand the related  physical-chemical phenomena to calculate the reaction likely to happen by adding any additive. A plasticiser, for example, can affect the transformation process and also the article’s tribological properties. The same as a stabilising additive can affect mechanical properties, electrical and thermal conductivity. Different additives can also produce synergetic effects.

Characteristics

Some of the physical-mechanical properties that are influenced by additive masterbatches are:

  • Mechanical properties
  • Thermal resistance
  • Light resistance
  • Ozone resistance
  • Flame-resistance and self-extinguishing properties
  • Rheology
  • Thermal and electrical conductivity
  • Specific gravity
  • Resistance to fungi and bacteria
  • Traceability
