2. Casting - Wikipedia

   en.wikipedia.org/wiki/Casting

   Plaster and other chemical curing materials such as concrete and plastic resin may be cast using single-use waste molds as noted above, multiple-use 'piece' molds, or molds made of small rigid pieces or of flexible material such as latex rubber (which is in turn supported by an exterior mold). When casting plaster or concrete, the material ...

3. Foam latex - Wikipedia

   en.wikipedia.org/wiki/Foam_latex

   To create foam latex, a liquid latex base is mixed with various additives and whipped into a foam, then poured or injected into a mold and baked in an oven to cure.The main components of foam latex are the latex base, a foaming agent (to help it whip into a froth), a gelling agent (to convert the liquid foam into a gel), and a curing agent (to turn the gelled foam latex into a solid when baked).

4. Talalay process - Wikipedia

   en.wikipedia.org/wiki/Talalay_process

   The Talalay process is a method of producing molded pieces of latex foam rubber. A liquid latex rubber base is introduced to a closed mold and is then vacuumed of air. The mold is then frozen to stabilize the cell structure. Carbon dioxide gas is introduced and the mold is heated to cure the rubber.

5. 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 ...

6. Foam rubber - Wikipedia

   en.wikipedia.org/wiki/Foam_rubber

   Foam rubber (also known as cellular rubber, sponge rubber, or expanded rubber) is rubber that has been made with a foaming agent so that its structure is an air-filled matrix. Commercial foam rubber is generally made of synthetic rubber, natural latex, or polyurethane. Latex foam rubber, used in mattresses, is well known for its endurance.

7. Resin casting - Wikipedia

   en.wikipedia.org/wiki/Resin_casting

   A flexible mold can be made of latex rubber, room temperature vulcanized silicone rubber, of which there are two types:Tin catalysed [2] (sometimes called condensation cured due to the alcohols weeping out as a by product of the reaction) or Platinum [3] (or addition cured, thus no byproduct) catalysed. Other similar materials can be used at ...
