1 antioxidants antidegradants polymer degradation chemistry
Antioxidant polymer stabilizers are widely used to prevent the degradation of polymers such as rubbers, plastics and adhesives that causes a loss of strength and flexibility in these materials. Polymers containing double bonds in their main chains, such as natural rubber and polybutadiene, are especially susceptible to oxidation and ozonolysis.

-KONTAKT 35 1. Introduction
continuous pressureless vulcanization methods (e.g. UHF, LCM or Hot-Air-Vulcanization) are commonly used in the rubber industry. An important elastomer for the production of tubes and profiles is certainly EPDM. The use of calcium oxide (Deosec R/ RG) as a desiccant is compulsory for those processes to avoid porosity of the vulcanizates. As a result of the

Vulcanization | rubber manufacturing | Britannica
Vulcanization, chemical process by which the physical properties of natural or synthetic rubber are improved; finished rubber has higher tensile strength and resistance to swelling and abrasion, and is elastic over a greater range of temperatures. In its simplest form, vulcanization is brought about by heating rubber with sulfur.
