Black light seal foam enables low light transmittance and with excellent light shielding. With a wide range of compression force profiles, foam materials have many applications within electric vehicles (EV), wearable devices, smart appliances, smartphones, tablets, computers and other devices. Foam is a workhorse within electronic devices. Exceptionally lightweight, foams are constructed to be durable, robust materials and ideal converting solutions. When used as a gasketing material, foams may be used to deaden noise pollution from devices and even block light.
