What are the impact modifiers used in polypropylene outdoor seating?
Polypropylene outdoor seating requires specialized impact modifiers to improve durability and resistance to environmental stressors. Common modifiers include elastomers like EPDM (ethylene propylene diene monomer) and SEBS (styrene-ethylene-butylene-styrene), which enhance flexibility and shock absorption. Mineral fillers such as talc or calcium carbonate are also used to improve stiffness and impact resistance. Additionally, UV stabilizers and antioxidants are incorporated to prevent degradation from sunlight and weathering. These additives ensure polypropylene furniture remains robust, crack-resistant, and long-lasting even in harsh outdoor conditions. Understanding these modifiers helps manufacturers optimize performance for outdoor applications.
