High Heat Resistance Sulfur Rubber Chemical Additives in Netherlands
Sulfur Content | Polymer Chemical Characterization | Smithers
This sulfur cure or vulcanization process imparts the recovery properties for which rubber is noted. Sulfur vulcanization promotes strength, toughness, fatigue resistance and improved wear characteristics to the completed product. Quantitative sulfur determination is necessary to permit reconstruction of a sulfur-cured rubber formulation.

Rubber - Additives | Britannica
Rubber - Rubber - Additives: A number of ingredients are added to both natural and synthetic rubber in order to obtain certain desirable properties. By convention, mix formulations begin with the amount of the designated elastomer—for instance, natural rubber (NR), butadiene rubber (BR), or styrene-butadiene rubber (SBR)—given as 100 parts by weight.

An overview of chemical additives present in plastics
Chemical recovery (tertiary recycling), involves chemicals, e.g. raw materials such as monomers, being recovered and/or converted from the plastic material . This can potentially be done by catalytic depolymerisation or by controlled thermal degradation, such as thermolysis, which is a non-catalytic cracking process [16] .

Enhancing the reversion resistance of natural rubber
This chemical is extremely soluble in rubber compounds and offers a unique activation for sulfur-cured systems. As a result, fewer regions of the vulcanizate become highly cross-linked (which improves reversion) and fewer regions are lightly cross-linked (which improves heat build-up).

Polymer stabilizers
Stabilizers are a class of chemical additives commonly added to polymeric materials, such as plastics, to inhibit or retard their degradation. Polymers can be subject to various degradation processes, including oxidation, UV-damage, thermal degradation, ozonolysis, combinations thereof such as photo-oxidation, as well as reactions with catalyst residues or other impurities.
