Caoutchouc

What is caoutchouc?

Elastic polymers – from which rubber is made – are known as caoutchouc. There are two types of caoutchouc: synthetic caoutchouc, which is produced based on petrochemical raw materials, and natural caoutchouc, which is mainly obtained from the white sap of the caoutchouc tree.

By reacting with sulfur, caoutchouc turns into rubber. This process is known as vulcanization. When this rubber compound, is heated to 145°C (293.0°F), it becomes sticky. At over 170°C (338.0°F) it dissolves and finally burns with a still flame.

Excellent release properties

Caoutchouc is also processed into, for example, sealing profiles. Liquid rubber has to be poured into molds, in order to take on the desired sealing form. To prevent the sticky mass from sticking to the molds, a release paper is often placed between the molds and the mass.

BRANOperl is a paper coated on one or both sides, which can be used excellently as a release paper The paper has good heat resistance and is available in a bleached or unbleached version. Due to its excellent release properties, it reliably prevents strips or sheets of material from sticking together or to other materials.
