Regalite hydrocarbon resins

​Regalite™ hydrocarbon resins are made from mixed aromatic/aliphatic resins which are subsequently selectively hydrogenated to produce a wide range of materials with low color, high stability and broad compatibility. Selective hydrogenation is the key to controlling the exact aromatic/aliphatic balance of the product which in turn determines the compatibility and application of the product. Regalite™ resins with a low level of hydrogenation will be more compatible with aromatic or polar polymers such as high vinyl acetate types of EVA. More highly hydrogenated grades will be more compatible with nonpolar polymers such as polyolefins. Each of the Regalite™ hydrocarbon resins can be used to achieve an optimal balance of mid-block and end-block compatibility in styrenic block copolymer formulations. Regalite™ hydrocarbon resins are available in a wide softening point range from liquid up to a softening point of 125°C.
