Mar 14, 2013· Sometimes, there is a misconception that a rubber compound is one ingredient and is the same for every different polymer type. This could not be further from the truth. A rubber compound could be a combination of 3 to 15 different ingredients of thousands of different compositions and vendors. A typical rubber formation based on parts per hundred is: Polymer 100 phr Filler 30 - 60 phr ...

Addivant™ supplies a range of phenolic, phosphite & amine antioxidants in solid & liquid forms for the elastomer & latex industries. These are added to the rubber during processing to achieve the performance characteristics required for different applications, or to the emulsion elastomers before coagulation to protect the polymer latex during finishing & storage.
Nov 03, 2017· PVC COMPOUNDING & PROCESSING TECHNIQUE: POLYVINYL CHLORIDE:. PVC is a product based on two of the earth's natural resources, salt and oil. Salt water electrolysis yields chlorine (in addition to caustic soda and hydrogen).
The first step in rubber compounding is mastication or polymer "breakdown". This is essentially development of the polymer's viscoelasticity to make it receptive to the additives. Most synthetic elastomers are produced with the uniformity in chemistry, viscosity and stability that minimizes or precludes the need for mastication.
