Triblock copolymers–modified SBR/EPDM rubber blends

Abstract

Butadiene-styrene/ethylene-propylene-diene monomer rubber blends were prepared with different blend ratios and modified with styrene-isoprene-styrene (SIS) and styreneisobutylene-styrene (SiBS) triblock copolymers as compatibilizers. Influence of the triblock copolymers on the blend compatibility was examined utilizing scanning electron microscopy and differential scanning calorimetric analysis. Thermal stability of the prepared rubber blend vulcanizates, with and without incorporation of SIS and SiBS copolymers, was assessed by determining their physico-mechanical properties after exposure to thermal aging accelerated. Furthermore, the swelling behavior of the rubber blend vulcanizates under investigation was evaluated in organic solvent, oil, and in brake fluid.

“…SBS elastomerinin kimyasal formülü [23] Şekil 2. SIS elastomerinin kimyasal formülü [24] Şekil 3. SEBS elastomerinin kimyasal formülü [25] Etilen vinil asetat (EVA) kopolimeri, mekanik özelliklerde yüksek ve çok yönlü performansı nedeniyle en çok kullanılan polimer tiplerindendir fakat düşük sıcaklıkta sınırlı performansa sahiptir.…”

Vulcanization, static mechanical properties, and thermal stability of activated calcium silicate/styrene‐butadiene rubber composites prepared via a latex compounding method

“…Rubber is an important polymer material with high elasticity, which is commonly used in the pharmaceutical, automotive, aerospace, military, and health industries 1,2 . Owing to its resistance to cracking, aging, weathering, and wear, styrene‐butadiene rubber (SBR) has been a focus of increasing interest in recent years, particularly in the context of the development of so‐called “green tires” 3–6 . Approximately 74% of global SBR consumption is associated with the production of products other than tires including conveyor belts, extruded rubber products, molds, hoses, and assorted consumer products 7 .…”
