A Mathematical Model for the Devolatilization of EPDM Rubber in a Series of Steam Stripping Vessels
… model for the stripping section of an industrial EPDM rubber production process was developed for a three-tank process, and two four-tank processes. The experiments that were conducted to determine model parameters such as equivalent radius for EPDM particles, as well as solubility and diffusivity …

Compatibilisation and stabilisation of immiscible polymer blends by reactive processing
… (PP), ethylene propylene diene monomer (EPDM) and mixtures of PP-EPDM, and to optimise synthetic routes for production of PP/EPDM copolymers for the purpose of compatibilisation of PP/EPDM blends. The MA-functionalisation was achieved using an internal mixer in the presence of low …

Mechanochemical synthesis and evaluation of rubber-thermoplastic polymer blends
… dicumyl peroxide. Ethylene-propylene terpolymer (EPDM)was also used in an attempt to improve the adhesion between the two phases. However, the results shown in this work con firm that no such interaction takes place in the presence of EPDM and the overall properties of the blend is lower than in …

A methodology for developing high damping materials with application to noise reduction of railway track
… types of viscoelastic material, butyl and EPDM rubbers with various amount<br/>of fillers and plasticisers are investigated. The properties of both rubbers have been<br/>measured over the range of temperatures for frequencies 300-3000 Hz. For this a test<br/>rig had to be modified. For …

A techno-economic study of the recycling of mixed plastics to useful products
… increase the toughness of the blends (e.g. EPDM in PE/PP blend and SBS in PE/PS blend). Also, EPDM is found to be very effective for improving the toughness of single component polypropylene. However, the improved Technical properties of such blends have been accompanied by a fast rate of …
