Electronic Grade Foams protect devices against shock.
Press Release Summary:
Used as shock pads, spacers or snubbers, energy-absorbent CONFOR foams help protect hard disk drives, miniaturized computers, hand-held electronics and PDAs from shock and vibration, with no silicone off-gassing. Semi-open celled foams also provide acoustical insulation. CF-40E low-stiffness formulation and CF-45E medium stiffness formulation meet HF-1 of Underwriter's Laboratory's UL94 flame standards at 2mm and 2.5mm thicknesses. Original Press Release:
E-A-R Offers Electronic-Grade Formulation Of CONFOR(R) Foam
Two non-silicone formulations of highly damped, slow-recovery CONFOR® foam now are available from E-A-R Specialty Composites. Both CF-40E-a low-stiffness formulation-and CF-45E-a medium stiffness formulation-meet HF-I of Underwriter's Laboratory's UL94 flame standards, at 2-mm and 2.5-mm thicknesses.
CONFOR CF-E-grade foams specifically address the shock protection needs of today's hard disk drives, miniaturized computers, hand-held electronics and personal digital assistants (PDAs). Used as shock pads, spacers or snubbers, the energy-absorbent foams help protect delicate components from shock and vibration, with no silicone off-gassing. The semi-open celled foams provide acoustical insulation as well.
Even as thin as 2 mm, CONFOR CF-E cushions and shock pads absorb and dissipate up to 97 percent of shock energy, without recoiling and amplifying the effect. In hard disk drives, they help protect against handling-related damage. In electronic devices, they help prevent circuit boards from colliding, speakers from crashing into the shell and LCD screens from cracking. Used as speaker and microphone seals, they can reduce audio distortion and background noise.
Non-silicone CONFOR CF-E foams have virtually the same physical and dynamic performance properties as the comparable, classic CONFOR formulations. Like all CONFOR formulations, CF-E foams are engineered to compress and conform under sustained pressure, and to slowly rebound when the weight is released. But when the foams receive a direct impact, they behave like semi-rigid foams, resist collapse and absorb the impact internally.
E-A-R Specialty Composites is a leading manufacturer and supplier of high performance materials that control unwanted mechanical energy-noise, vibration, shock and motion.
