Through the use of additives during processing, plastics achieve their technical and optical properties. Requirements such as durability, appearance, feel, flammability, etc. are largely determined by additives. Through a professional selection of the correct additives, each plastic component can be given its individual performance.
Antimicrobial additives protect plastic surfaces against the growth of microorganisms such as algae, bacteria or fungi. They are embedded in the polymer matrix and prevent the spread of microorganisms through chemical reactions.
Antioxidants for plastic additive
Antioxidants react with radicals in the polymer chain, which are formed in the processing process and thereby stop unwanted molecular chain degradation or composition.
Antistatics for Plastic additives
Dust explosions caused by electrostatically charged plastic surfaces cause devastating damage, especially in manufacturing companies. Permanent antistatic agents prevent these charges and consequently significantly reduce the risk of explosion. In addition, the use of antistatics minimizes dust pickup on components.
Flame retardants for plastic additives
Flame retardants suppress the flammability or retard the flammability of polymers. By adding it, it is possible to achieve a variety of fire protection classes and criteria, which are partly required for the use of plastics in certain applications.
Lightstabilizers for plastic additives
Light stabilizers such as UV absorbers and HALS (sterically hindered amines) protect the polymer from UV radiation in sunlight. The discoloration caused by UV radiation, embrittlement or cracking is delayed by the use of these additives.
Multi-component additive packages
Additive packages make it easier for the processor to precisely dose the additives. Several additives are contained in a blend and adapted in their product form to the application criteria of the processor.
Nucleating agents for plastic additives
The addition of nucleating agents influences the crystallinity and the crystal structure in order to achieve greater transparency. They are soluble in the melt and achieve a much higher nucleation density.
Optical brighteners for plastic additives
An optical brightener is a finishing agent to achieve a high degree of whiteness. These are chemical compounds with fluorescent properties, which are introduced into the plastic in the same way as dyes and cause lightening. Another field of application exists as a fluorescence indicator for various materials and applications.
Process & heat stabilizers
Process stabilizers are radical scavengers and protect the polymer during processing from unwanted chain degradation / buildup.
In addition to aging and sunscreen agents, there are a variety of specialties with which the required properties of the polymer can be achieved.
