This product combines the lightness of foam with the proven power of traditional sponge rubber. The new S-600 and S-800 silicone foam tapes from Pres-On seal and protect outdoor communications, electronics cabinets, HVAC units and lighting enclosures from rain, fine particles, and extreme climates. Both tapes are recognized for flame retardance and gasketing. Available in several thicknesses, colors and lengths up to 60 feet, the medium density tapes feature either an acrylic or silicone pressure-sensitive adhesive on one or two sides. The company says that both tapes exhibit excellent “memory” and resistance to ultraviolet light, ozone and corrosion.
