When designing to protect portable device displays, thinner profiles, variations in manufacturing tolerances, fluctuating temperatures, waterproofing, and drop tests all add to the challenge. PORON® Polyurethane Foams offer a broad portfolio of solutions to absorb and distribute impact energy and protect displays from shock, dust, moisture and particulates.

Shock Protection

To protect displays from the shock of impact, a display or LCD gasket must absorb and distribute impact energy to prevent cracks or other damage due to mechanical shock. PORON® Polyurethane Foams absorb and distribute impact energy, helping to prevent unwanted cracks in display screens. PORON ShockSeal® (4790-79) foam or PORON 92 polyurethane foam (4790-92) offer excellent protection from mechanical shock and impact damage.

Display Back Pads

For tablet and other device touch screens, display back pads help deliver an excellent user experience and provide long term reliability. Back pad applications require extremely soft material that can distribute force, provide good compression set and compressibility with low push-back force, as well as good stress relaxation resistance. PORON® SlimGrip™ SGRL-06020 polyurethane foam is an ideal solution for many touch screen back pad applications.

Ruggedized Displays

In outdoor or industrial touch screen applications, the LCD display must weather vibrations, physical shocks, and temperature fluctuations, while providing sealing and gap-filling with a high degree of conformability. PORON Polyurethane Foams, particularly the PORON 40 and 50 Series, are known by industrial designers for their exceptional durability and long-term performance. Highly resilient, the PORON 40 and 50 Series, are known by industrial designers for their exceptional durability and long-term performance and offer good levels of vibration isolation and impact absorption under rigorous conditions.
