Descrizione dei prodotti
Coace® W5A-2 è un elastomero poliolefinico modificato con glicidilmetacrilato ad alto tasso di innesto.
In the field of material science, the quest of increasing the toughness and resilience of polyester-based materials has resulted in ground-breaking discoveries. Among these, one product stands out: a polyester toughener with a high glycidyl methacrylate concentration. This product, distinguished by its glycidyl methacrylate-modified polyolefin elastomer with a high grafting rate, promises to revolutionize the performance and versatility of polyester materials in a variety of industries.
This sophisticated polyester toughener is based on a painstakingly developed glycidyl methacrylate modified polyolefin elastomer. This structure is intended to maximize toughness and compatibility with polyester matrices, hence improving overall material qualities. Through high grafting rates, the toughener forms strong interfacial connections with polyester, giving the composite material excellent toughness and resilience.
