In-mold(IM)-type

In-mold (IM) type of keypads are a combination of injection molded plastic parts and liquid silicone material molded around the plastic parts.
In-mold type of keypads are used for remote keyless entry modules. The characteristics of molded thermoplastics do not provide durable formed parts under harsh environmental circumstances as shapes may deform at higher temperatures. Silicone rubbers however are polymer materials that provide molded shapes by chemical cross linking, making parts very durable and rigid over a long term. The adhesion between plastic frame parts or plastic buttons and the silicone rubber is based on Shin-Etsu superb knowledge of matching silicone rubbers with other materials as shown with the PB-type of keypads and the variety of Inter-Connector products.

Specifically for automotive parts, Shin-Etsu IM-type is very suitable for making membrane switches for RKE units or doorlatches.
