Impact Modifiers

SpectraSyn liquid polymer modifiers improve polyolefins by enhancing their performance range. SpectraSyn polymer modifiers can be used to enhance impact strength, flexibility, elongation, elasticity, and optical properties of all types of polyethylenes, polypropylenes, TPOs, TPVs, ethylene plastomers, and specialty olefinic TPEs. They also have some compatibility with styrenic TPEs such as those based on SEBS. SpectraSyn polymer modifiers are highly compatible with polyolefins and have minimal effect on heat resistance. They also improve processability and filler dispersion by lowering melt viscosity, which can improve cycle times and line speeds.

SpectraSyn liquid polymer modifiers improve polyolefins by lowering their melt viscosity, which enables faster cycles and line speeds and also aids filler dispersions. These modifiers also enhance flexibility, toughness, and elasticity of polyethylenes, polypropylenes, TPOs, TPVs, ethylene plastomers, and specialty olefinic TPEs.

Novel Liquid Modifiers for Polyolefins Have Multiple Functions
A family of liquid polymer modifiers with a proven track record in EPDM compounds has been expanded for use in a broad range of polyolefins.
Metallocene PP & PE Weld Strongly to Each Other
Multilayer film applications such as packaging and diapers are just two areas that could benefit from spot welding (instead of gluing) polyethylene to polypropylene. Normally these two resins show poor adhesion to each other. But two years of research at the University of Minnesota in Minneapolis and at ExxonMobil Chemical in Houston show that metallocene-catalyzed polyolefins can weld to each other with bond strengths much greater than are possible with conventional Ziegler-Natta catalyzed polyolefins.
