Additives are substances that are used in the manufacture of products. These additives are added to specifically influence certain properties of the product. These properties may be involved, for example:
- Ageing resistance
Additives are characterized by the fact that they only make up a small proportion of the amount of material used in the product. This distinguishes them from fillers, which can take up a significantly higher volume.
#1 Definition Additive
Additives are additives that are added to products in small quantities in order to specifically influence certain product properties.
#2 Additives in sealing technology
Elastic sealing elements such as O-rings usually consist of elastomer materials that are composed according to extensive formulations.
These are also known as compounds. In addition to the base elastomer, additives and fillers are also used in production. Additives are used, among other things, for ageing protection, improved vulcanization or conductivity.
Additives therefore play an important role in matching sealing elements to their intended use.
