Plastics are materials that consist of synthetic or semi-synthetic organic compounds that can be formed into objects of various shapes. They are usually high molecular weight organic polymers containing a number of other substances called additives that are designed to change the processing and performance properties. Due to their properties, they can replace most natural materials, such as wood, stone, leather, glass, metal or ceramics. In addition, their features and functions can be designed depending on the application.
 

Polymer additives – why do we use them?

The industry uses many types of polymer additives that can be divided into four main groups:

Processing stabilizers

• Thermal stabilizers – they are used in the case of polymers that tend to decompose at processing temperatures.
• Process antioxidants – they are used to prevent the oxidation of polymers, as well as the formation of post-transformation (e.g. branching) during processing.

The PCC Group’s offer includes a number of such substances in the form of products from the Rostabil series, which as additives have a wide range of applications in the plastics industry. These products have antioxidant properties, they can also act as thermal stabilizers, preventing degradation of plastics during processing. They are also used as process stabilizers. The Rostabil series has high hydrolytic stability, does not adversely affect the mechanical properties of materials and prevents degradation during thermal processes.

Property Modifiers

• Mechanical properties modifiers – they are plasticizers, impact modifiers, foaming agents and cross-linking agents. This product group includes the Roflex series, i.e. professional high viscosity plasticizers. They have many times better migration resistance compared to standard plasticizers based on traditional PVC formulations. Accessories from the Roflex series are widely used in construction (technical films, coverings), electronics (cable insulation), furniture (projection screens, artificial leather), automotive (car upholstery), as well as transport (conveyor belts and tarpaulins).
