ASPECT 4222

ASPECT 4222 is a fine, high aspect ratio wollastonite recommended for use in advanced materials. ASPECT 4222 offers good reinforcing properties, improved rheology, compressive strength, thermal stability, reduced coefficient of thermal expansion, dimensional stability and can act as a synergist in polymer composites. This product can be surface treated to further improve mechanical performance and coupling to the matrix. Surface treated grades can improve weld line and tensile strength. ASPECT 4222 provides benefits such as improved mechanical properties, thermal stability and dimensional stability which are highly desirable in advanced material applications.
