Description
Material Notes:
U series resins are polymer alloys that are improved in resistance to oils and chemicals, the shortcoming of amorphous resins. They are transparent and have a greater moisture blocking property than other resins having similar structures. They are also suitable for blow molding.Characteristics:Transparent, resistant to chemicals, especially to oils, alcohols and others Weather Resistance Blended into PET resins for improvement in heat resistance.Information provided by Unitika Ltd.
