Recent developments in the synthesis of poly(hydroxybutyrate) based biocomposites

“…They have chemical and impact resistance while they are expensive than the thermosets and melt on heating to certain temperatures. 50 The polymers like, poly(ethylene) (PE), poly(ethylene terephthalate) (PET), poly(styrene) (PS), and poly(vinyl chloride) (PVC) are considered as conventional thermoplastic polymer materials. 51 They are not fully biodegradable and cause environmental pollution, which limits their applications in biocomposites development.…”

“…Thermoplastic materials become soft when heated as they are not cross‐linked and can be recycled or remolded easily. They have chemical and impact resistance while they are expensive than the thermosets and melt on heating to certain temperatures . The polymers like, poly(ethylene) (PE), poly(ethylene terephthalate) (PET), poly(styrene) (PS), and poly(vinyl chloride) (PVC) are considered as conventional thermoplastic polymer materials .…”

Design and Manufacturing of a Disposable, Cyclo-Olefin Copolymer, Microfluidic Device for a Biosensor †

“…These materials afford the implementation a variety of structures, while keeping desirable features such as low cost production, chemical resistance and mechanical strength [ 5 , 8 ]. Thermoplastic materials, in addition to these qualities, offer flexible manufacturing possibilities through different techniques (milling, hot embossing, injection molding) [ 9 ]. Although semi-crystalline and amorphous thermoplastics have been employed to produce molded parts, the later type of material displays a wider molding temperature range, which allows a more flexible usage of replication techniques [ 10 ].…”

“…Although semi-crystalline and amorphous thermoplastics have been employed to produce molded parts, the later type of material displays a wider molding temperature range, which allows a more flexible usage of replication techniques [ 10 ]. Amorphous thermoplastics such as polystyrene (PS), polycarbonate(PC), polyvinyl chloride (PVC), poly(methyl methacrylate) (PMMA), cyclic olefin copolymer (COC) and cyclic olefin polymer (COP) are found as usual materials of microfluidic substrates [ 5 , 7 , 9 ].…”

Polybutene-1 tube with in situ microfibering polystyrene via helical convergent flow: an economical pathway to continuously fabricate biaxially reinforced polyolefin tubes for medical application

“…tubes and catheters, have been indispensable for the treatment of critical cases since they offer additional and essential advantages such as ease of manufacturing, low cost, and disposability. 1 Being amenable to gamma and electron beam radiation sterilization and effectively reducing the occurrence of infectious diseases, polyolen-based single-use products are considered as the most promising and recommended polymeric devices for medical use. 2,3 The mass production of polyolen tubes or catheters, i.e., extrusion, shows two signicant defects: the weld line issue and the axial orientation, exposing aws in lessened mechanical performances in the hoop direction.…”
