Technical Article Briefs
Reclaiming ground tire rubber at low temperatures: benefits and limitations
Lower extrusion temperatures during rubber reclamation lead to a reduction in toxic degradation products and improve the mechanical properties of vulcanizates, at the expense of reduced processability.
Flame retardancy of halogen-free composites prepared by rapid heat cycle molding
Adding glass fibers to polycarbonate/acrylonitrile butadiene styrene composites aggravates combustion by a ‘candlewick’ effect.
New biodegradable composites for food packaging
Beer spent grain fibers are a biodegradable waste resource that forms breathable thin films by conventional extrusion film blowing under processing conditions scalable to industrial production.
Foaming mechanism and control in microcellular injection molding
The formation mechanism of inner and external bubble morphology, and of the solid skin in microcellular injection molding, is elucidated and verified for effective bubble morphology control.
Green technology for modification of poly(vinyl chloride)
Biodegradable poly(hydroxybutyrate) copolymers plasticize, toughen, improve processing, and reduce UV discoloration.
Biopolyesters filled with date seed powder
Using date seed powder to reinforce the biodegradable polyesters poly-L-lactide and poly(butylene adipate-co-terephthalate) improves their properties.
Post-industrial waste nylon for automotive applications
Although slightly lower in tensile and fatigue strength, glass-fiber-reinforced waste nylon can be a viable substitute for reinforced prime nylon in cyclically loaded under-hood automotive applications.
Enhancing properties and value of recycled plastics
Adding graphene nanoflakes to recycled high-density polyethylene drastically improves its performance.
Bioplasticized poly(vinyl chloride)
Treatment with epoxidized soybean oil and bis(2-ethylhexyl) succinate for wire and cable applications softens the polymer but preserves tensile elongation properties after heat aging.
Synthesis and properties of polystyrene/silicon dioxide nanocomposites
An in situ sol-gel process enables good compatibility between organic and inorganic phases and leads to increased thermal stability with increasing inorganic content.
Modified resin for high-performance composites
A simple and practical modification makes a new class of phenolic resinâ€â€benzoxazine resinâ€â€stronger and more resilient.
Voids in composites with continuous fiber reinforcement
An enhanced void formation model was developed to accurately predict the void content of composite laminates fabricated from prepreg after humidity exposure and across a range of processing pressures.
Effect of chemical treatment on newspaper fibers
De-inking and modifying newspapers with acetic anhydride, sodium hydroxide, and potassium permanganate enhances interfacial adhesion between a polyvinyl chloride matrix and the newspaper fibers.
Screw speed and nanocomposite rheology
Process conditions affect the intercalation, exfoliation, slippage of polymer chains, and relaxation times of polymer-clay nanocomposites.
Typical interactions of composite additives with polyethylene and nanoclay
Maleated polyolefins are commonly used to compatibilize wood fiber-reinforced composites, but can decrease tensile strength. Dicumyl peroxide may be a superior choice when natural fibers are not used.
Toughening epoxy with liquid and preformed powdered rubber
Phase-separation-formed submicron liquid rubber and preformed powdered nanoscale rubber fillers balance the mechanical and thermal properties of epoxy resin nanocomposites.
Exploring the mixing performance of triple-screw extruders
The central region of the triangle-arrayed triple-screw extruder has an extension effect in processing that plays an important part in compounding high-viscosity-ratio polymers.
Facile exfoliation of graphite for preparation of polypropylene/graphite nanocomposites
Combining rotating solid-state mixing and dynamic packing injection molding enables graphite flakes to be well-exfoliated and dispersed in polypropylene matrices, resulting in high-performance composites.
Enhanced cold crystallization of glassy poly(L-lactic acid)
Glassy PLA samples prepared by rapid compression possess lower onset crystallization temperature, higher crystallization rate, and larger final crystallinity than samples prepared by other methods.
Antibiotic wound dressings
Incorporating ampicillin into electrospun polyurethane makes bandages that control common infections.
