Abstract
The invention relates to a hydrocarbon wax composition with superior properties as ozone- and aging-protecting additive in rubber products, the production thereof and the use thereof as ozone- and aging-protecting additive. The hydrocarbon wax composition is characterized by its distribution of hydrocarbon molecules by number of carbon atoms per hydrocarbon molecule and its distribution of branched and linear hydrocarbons.
Claims16
A hydrocarbon wax composition comprising hydrocarbons with 15 to 110 carbon atoms, wherein
- 25 to 40% of the hydrocarbons are linear short chain length hydrocarbons having 20 to 30 carbon atoms;
- 5 to 18% of the hydrocarbons are linear medium chain length hydrocarbons having 31 to 38 carbon atoms;
- 25 to 40% of the hydrocarbons are linear long chain length hydrocarbons having 39 to 60 carbon atoms;
- 5 to 15% of the hydrocarbons are branched short chain length hydrocarbons having 21 to 31 carbon atoms;
- below 5% of the hydrocarbons are branched medium chain length hydrocarbons having 32 to 39 carbon atoms;
- and
- 5 to 15% of the hydrocarbons are branched long chain length hydrocarbons having 40 to 61 carbon atoms;
- wherein the percentage in each case is relative to the total number of hydrocarbons having 15 to 110 carbon atoms.
