Acrylic PolymersARUFON®

ARUFON® is a general name for our acrylic polymer products obtained through Uniform Functional Oligomer (UFO) technologies, which are being developed by Toagosei. UFO technology is used to manufacture low molecular weight polymers with 100% efficiency by continuous polymerization of composite materials at high temperatures, especially acrylic monomers.



ARUFON® obtained through UFO technology is 100% polymer, so it is environment-friendly and uses almost no auxiliary materials such as chain transfer agents in accordance with high temperature continuous polymerization procedures, making it an acrylic polymer with superior durability (including weather resistance and heat resistance). Additionally, it is possible to manufacture acrylic polymers over a wide range of glass transition point (Tg) and molecular weight range by using raw materials with different characteristics.
