Rubber curing process

Vulcanization (British: Vulcanisation) is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include … See more Rubber—latex—had been known for thousands of years in Mesoamerican cultures, used to make balls, sandal soles, rubber bands, and waterproof containers. Rubber was processed for specific applications within the See more In contrast with thermoplastic processes (the melt-freeze process that characterize the behaviour of most modern polymers), vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible.

WebThe rubber is placed in the process of mixing with raw materials, and after complete mixing, it enters the second stage, which is called rubber curing, and the desired part, under certain pressure and temperature, is baked by press machines. This stage when sulfur is added as a rubber curing agent is called vulcanization. WebFeb 18, 2016 · Mastication, the process by which the viscosity of natural rubber is reduced to a suitable level, is an important step in the mixing process. Rubber polymers such as Natural Rubber (NR) require mastication to reduce their viscosity/elasticity and to even out variations between different polymer lots.
