2. Vulcanization - Wikipedia

   en.wikipedia.org/wiki/Vulcanization

   Worker placing a tire in a mold before vulcanization. Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. [1] 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 ...

3. Thermoplastic vulcanizates - Wikipedia

   en.wikipedia.org/wiki/Thermoplastic_vulcanizates

   This resulted in the commercialization of "Uniroyal TPR" thermoplastic rubber. [5] [6] TPVs are a blend between a thermoplastic matrix and vulcanized rubber - combining the properties of both. A combination of elastomeric properties, including compressibility, tension sets, aging performance, and chemical resistance, characterizes TPVs.

4. Membrane roofing - Wikipedia

   en.wikipedia.org/wiki/Membrane_roofing

   These are: (1) Cured (or vulcanized) elastomers, (2) Uncured elastomers, and (3) plastomers. Cured Elastomers (often referred to as Thermoset) – Thermosets are synthetic rubbers that have undergone the vulcanization or "Curing" process. Seams of materials are bonded by adhesives or chemicals, which over time weaken and separate unless ...

5. Sulfur vulcanization - Wikipedia

   en.wikipedia.org/wiki/Sulfur_vulcanization

   Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur [citation needed] or sulfur-containing compounds. [1]

6. Thermosetting polymer - Wikipedia

   en.wikipedia.org/wiki/Thermosetting_polymer

   In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer . [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst .

7. Spin casting - Wikipedia

   en.wikipedia.org/wiki/Spin_casting

   The spin casting process typically uses vulcanized silicone or organic rubber as the mold-making substrate. Vulcanization is an integral step that occurs halfway through the mold-making process. Prior to vulcanization, the mold rubber is a soft and malleable solid-like fluid, in many ways very similar to Silly Putty. Because of the clay-like ...

8. RTV silicone - Wikipedia

   en.wikipedia.org/wiki/RTV_silicone

   RTV silicone rubber can be used to cast materials including wax, gypsum, low-melt alloys/metals, and urethane, epoxy, or polyester resins (without using a release agent). A more recent innovation is the ability to 3D print RTV silicones.

9. Cross-link - Wikipedia

   en.wikipedia.org/wiki/Cross-link

   In vulcanization, sulfur is the cross-linking agent. Its introduction changes rubber to a more rigid, durable material associated with car and bike tires. This process is often called sulfur curing. In most cases, cross-linking is irreversible, and the resulting thermosetting material will degrade or burn if heated, without melting.
