Studies have revealed that EVAL with hydrophilic groups responds well to electron beam-induced graft polymerization. This led to the discovery that SOPHISTA fiber made from EVAL is also very effective at metal collection.

About FELIBENDY
The world's first nonwoven fabric made using steam jet technology. Utilizing Kuraray's proprietary SOPHISTA as a raw material, the Company applies unique production conditions to produce a wide range of FELIBENDY nonwoven fabrics.
Nonwoven fabrics made from high-temperature, high-pressure processed SOPHISTA can be further processed to manufacture thick board with a number of functions, including air permeability, sound absorbency, shock absorption and insulation.
Kuraray is responsible for development and KURARAYKURAFLEX the production and sale of FELIBENDY.

About EVAL (ethylene vinyl alcohol polymer resin)
EVAL was developed by Kuraray as the world's first copolymer EVOH (ethylene vinyl alcohol polymer resin) in 1972. Its structure consists of a number of hydroxyl groups hanging from a chain of carbon hydrate (CH2). Owing to its gas impermeability, EVAL is used as a barrier material for food packaging materials and plastic gas tanks.
