SI Group Polymer Modifiers are the industry's leading compatibilizers, which are also known as functionalized polymers, coupling agents or impact modifiers. They are used in applications such as PVC calendaring, PVC profiles, engineering thermoplastics compounding, thermoplastic elastomers, epoxy adhesives and coatings, masterbatches, polyolefin compounding, filler coupling, solvent adhesives, and alloy compatibilization.
Problems Solved
Difficulties dispersion of polar fillers in non-polar polypropylene resins Poor adhesion of fillers to the polypropylene matrix High moisture absorption in polyolefin products and resins Creep and low flexural strength in thermoplastic products and formulations Low impact resistance and cracking issues in polyolefins and engineered resins Long lead time and supply issues of polyolefin compatibilizers and coupling agents
POLYBOND™ 7200 acts as a high-efficiency coupling agent for cellulose fiber-filled polypropylene by reducing water uptake and providing higher flexural/tensile strength and impact properties than convential coupling agents.
ROYALTUF™ 527 is a maleic anhydride grafted EPDM impact modifier that is especially useful for improving low-temperature performance polyamides. It is effective in improving physical properties of recycled nylon compounds.
Workhorse coupling agent for filled polypropylene and polyamide / polypropylene blends. Can be used with glass, mineral, or cellulose fiber reinforcing materials.
