Durability of rubber products - University of Twente Research
The invention of useful rubber is commonly attributed to Charles Goodyear.4 Natural or India rubber, as it was then known, had little uses. Rubber products melted in hot weather, froze and cracked in cold, and adhered to everything they touched. In 1830 Goodyear began experimenting with raw rubber to turn it into a useable product.

Rubber Recycling | Department MS3 - Universiteit Twente
The EU obliges the automotive industry to recycle at least 95% of the car materials before 2015, and this implies that the rubber industry cannot escape from recycling of the rubber parts anymore. Devulcanization of rubber breaks the polysulphidic crosslinks so that the polymer molecules can be vulcanized again for other rubber applications.

An in-rubber study of the interaction of silica with proteins present in natural rubber shows that the latter compete with the coupling agent during the silanization reaction; the presence of proteins makes the silane less efficient for improving dispersion and fillerpolymer coupling, and thus negatively influences the final properties of the

Warpage of rubber pressed composites — University of Twente
The rubber pressing process is applied for the rapid production of thermoplastic composite products. However, rubber pressed products show geometrical distortions, such as warpage, due to process-induced residual stresses. It is believed that these stresses build up as a result of the large thermal gradients that are present during consolidation.
