The case is the first line of defense against external impact. Making the most of the particular material properties of two types of plastic, the case of the CF-U1 is made from both polycarbonate and elastomer resin.
Polycarbonate resin is so strong and weatherproof that is often used for helmets and car bumpers.
By contrast, elastomer resin has excellent resilience and great tensile strength. Moreover, when impacted, molded elastomer is capable of shaking off the force and bouncing back to close to its original form. Having elastic properties and a feel similar to rubber, elastomers often feature in product design, such as in non-slip cell phone grips.
Because elastomer resin resists damage and is well able to absorb impact, it has already been used for parts of the body of the Toughbook CF-30.
Making the most of the properties of each of these plastics, the CF-U1 has a polycarbonate inner case, and a surrounding elastomer outer casing that is easy to hold. The case is designed to be tough and hard to break, at the same time, it absorbs shock and is easy to carry.
