SBS (Styrene-Butadiene-Styrene) is an effective toughening agent for recycled PS, addressing its inherent brittleness while maintaining processability. To balance performance and cost, here are key principles for selection:Molecular Weight Control: Optimal range is 80,000–200,000.Below 80,000: SBS t

EVA has become the mainstream base material for foamed shoes such as slippers, children’s shoes, and casual footwear, thanks to its low cost and excellent processability. However, EVA has clear shortcomings: insufficient resilience and support, weak abrasion and slip resistance, low tensile strength

SEBS (Styrene-Ethylene-Butylene-Styrene) is often called the “golden rubber” due to its outstanding weather resistance, aging resistance, recyclability, and the fact that it does not require traditional vulcanization. It has been widely applied in automotive, wire & cable, medical devices, electroni
