Molded silicone foam and sponge

The production of molded silicone foam usually involves a specific foaming process. There are two ways to vulcanize silicone rubber sponge model products: one-step method and two-step method. The one-step method is a one-time hair hole into a sponge of a certain shape and size in the mold, and the second stage vulcanization no longer hair holes; The two-step rule first vulcanizes the rubber in the mold for a short time, so that it initially develops holes and exactly forms a surface, and then it is placed in the oven and then develops holes into a certain shape and size.

The molded sponge has a porous structure, which makes the sponge have good elastic and cushioning properties. It is widely used in various fields, such as cushions, massage equipment accessories, automotive headrests and so on. In addition, sponges can also be used to make one-time products of various shapes.

When making molded silicone foam, it is necessary to pay attention to removing the bubbles in the rubber material to prevent damage to the sponge structure. The rubber material used for molding sponge products should be cut according to mold specifications after mixing and coated with spacer on the surface to prepare for mold vulcanization. Generally, talc powder is used as a spacer, and white carbon black can also be used.
To sum up, the production of molded silicone foam and sponge involves specific process flows and precautions, and they have a wide range of uses in daily life and industrial production.
