Potential applications of polycarbohydrates, lignin, proteins, polyacids, and other renewable materials for the formulation of green elastomers

Review of hospital plastic waste management strategies for Pakistan

“…For example, intravenous (IV) bottles of glass, tubing made of rubber, and surgical instruments of metals were used widely until the 1930s when IV bags of polyvinyl chloride (PVC), tubing of PVC, and catheters made out of silicone were introduced (Modjarrad and Ebnesajjad 2003 ). Nowadays, polymers, rubbers, and polymer composite–based materials have occupied the market in the field of food packaging, medical instruments, furniture, automotive, health care instruments, and various other applications (Abid et al 2012 ; Adeosun et al 2013 ; Gill et al 2018 , b , c ; Salernitano and Migliaresi 2020 ; Zagho et al 2021a ; Zeng et al 2021 ). The utilization of plastics in medical devices includes simple tools such as spatulas, syringes, and dressings along with complex instruments, i.e., MRI, X-ray machine, surgical devices, etc.…”

Upscale recycling of nonwoven polypropylene waste using a novel blending method

“…21 CB is named as the most efficient filler among all other fillers as its addition to rubber enhances the properties of rubber such as tear resistance, tensile strength, hardness, and viscosity. 22 Due to the inherent UV absorption property of CB, it also acts as a UV stabilizer for rubber and other plastics. 23 This research aims to study the variations in different properties of nonwoven PP waste by incorporating the CB nanofiller at different weight percentage loading.…”

High‐performance atactic polypropylene modified bitumen blends fabricated via conventional, hot, and in‐situ blending techniques

“…8 Various polymeric materials including polypropylene, 9 high-density polyethylene, 10 acrylonitrile butadiene styrene, 11 thermoplastic polyurethane, 12 polyethylene terephthalate 13 (self), nylon, 14,15 and various elastomers including natural rubber, nitrile rubber, styrenebutadiene rubber, carboxylated acrylonitrile butadiene, and hydrogenated acrylonitrile butadiene owing to their high-performance properties are used as modifiers in bitumen. [16][17][18] Cai et al 19 investigated the use of polyacrylamide as a stabilizer material and styrene as a coagulant to prepare latex-modified bitumen emulsions of styrene block copolymers (30% polystyrene).…”

“…Extensive studies on the utilization of polymers as a modifier in bitumen for property modification include improving fatigue resistance, minimizing reflective cracking, increasing low‐temperature cracking resistance, increasing tenacity (structural stability), and increasing thermal stability 8 . Various polymeric materials including polypropylene, 9 high‐density polyethylene, 10 acrylonitrile butadiene styrene, 11 thermoplastic polyurethane, 12 polyethylene terephthalate 13 (self), nylon, 14,15 and various elastomers including natural rubber, nitrile rubber, styrene‐butadiene rubber, carboxylated acrylonitrile butadiene, and hydrogenated acrylonitrile butadiene owing to their high‐performance properties are used as modifiers in bitumen 16–18 . Cai et al 19 investigated the use of polyacrylamide as a stabilizer material and styrene as a coagulant to prepare latex‐modified bitumen emulsions of styrene block copolymers (30% polystyrene).…”
