specialty elastomers
Exxelor™ modifiers
Exxelor™ modifiers are used to enhance the performance of a variety of engineered thermoplastics and other technical polymers. They are based on functionalized elastomeric and polyolefinic polymers and are produced through reactive extrusion.
With Exxelor modifiers, characteristics such as resistance to impact at low temperature, improved homogeneity and surface aspects in filled compounds can be advanced compared with untreated materials.
Roles for Exxelor modifiers
Impact modifiers
Exxelor modifiers improve the overall toughness of polymers. Under optimal dispersion, the rubbery phase of Exxelor modifiers helps improve impact strength and elongation. At higher levels, Exxelor modifiers can provide enhanced ductility in polyamide blends at low temperatures (down to -40°C/-40°F) while maintaining good heat resistance.
Compatibilizers
Acting as a solid surfactant, Exxelor modifiers increase interphase adhesion and achieve compatibility between most commonly used polar polymers and polyolefins.
Coupling agents
Exxelor modifiers promote chemical bonding between fillers, reinforcements and the polymer matrix.
Adhesion promoters
When added to nonpolar polymers, Exxelor modifiers enhance adhesion to materials such as metal, thermoset rubbers and most polar substrates, including glass.
