Coagulation is the first crucial step in the processing of natural rubber (NR) that happens naturally or is induced by various techniques. The mechanism of Hevea latex coagulation involves the destabilization and aggregation of latex particles that are influenced by different factors. By understanding the basics of coagulation process, the use of different coagulation techniques and their efficiency are illustrated in this paper. The corresponding impact on the technological properties of unvulcanized NR is connected to the choice of coagulation technique. For instance, the microstructure of natural coagulated NR relies on the precedence of microbial activities which further decides the mesostructure and macrostructure properties. As NR is widely used in the rubber manufacturing industry notably tyres, the subsequent impacts of coagulated NR using different techniques are described from the aspect of processing, vulcanization characteristics, mechanical properties, and ageing retention properties of NR vulcanizate. By providing such an overview, the connection of coagulation technique of Hevea latex to the rubber industries is established to have a more comprehensive understanding when selecting the best option for the respective application.
