Rogers, Connecticut - Rogers Corp has developed a polyurethane-foam-based cushioning material specifically for the protection of LCD screens of hand-held devices from shock.
Applications for the material, designated ShockSeal, include cell phones, netbooks and PDAs (personal digital assistants) where Rogers says it reduces impact force by more than four times that of competitive materials, making them more resistant to everyday shocks from being dropped, the firm claims in a 25 Oct announcement.
The materials are specifically engineered to meet the challenging cushioning, sealing and protection requirements that larger visual displays demand, says Rogers, adding that Poron ShockSeal foam is available in sheets as thin as 0.5 mm, and conveniently conforms to some of the smallest and most intricate manufacturing designs.
This will help equipment designers and manufacturers face new challenges with these increasingly complex technologies, such as the demand for thinner, larger and more expensive LCD displays, the Rogers statement added.
Poron ShockSeal foams have the same excellent compression set resistance as other Poron products, the firm asserts, and essentially the same outstanding compressibility as the Poron 92 formulation. This allows them to maintain spring forces over time and effectively seal out dust and other harmful particles, Rogers concludes.
