Silicone rubber for molding can be broadly classified into two types: silicone rubber compound (Millable Rubber) and LIMS (liquid silicone rubber injection molding system).

Positioning of Silicone Rubber for Molding

Excellent Properties of Silicone Rubber for Molding

Silicone rubber for molding has a number of features not found in other organic rubbers.
The diverse properties of silicone rubber not only enable high quality and high functionality of products, but also contribute to the efficiency of manufacturing processes and energy savings by offering a lineup of types that do not require post cure.

Application Examples of Silicone Rubber for Molding

They are used in a wide variety of products in fields ranging from automobiles to electrical and electronic equipment, machinery, leisure goods, and household goods.

General Properties of Silicone

High Binding Energy

Silicone (dimethylpolysiloxane), which has a siloxane bond (-Si-0-Si-) as its main backbone,
has a large binding energy of 106 kcal/mol, while the carbon bond (C-C) has 85 kcal/mol, and is very stable.

As a result, it has superior heat resistance, electrical insulation, and chemical stability compared to ordinary organic polymers.

Low Intermolecular Forces and High Coil-forming Capacity

Silicones have a helix structure (coiled) and are highly elastic due to low intermolecular forces,
compressibility, and excellent cold resistance.
In addition, the methyl groups located on the outside of the coil structure can rotate freely, resulting in unique interfacial properties such as water repellency and mold release.
