Physical and mechanical characterization of a recycled polypropylene and wood flour without additives
(Univ Fed Rio De Janeiro, Lab Hidrogenio, 2014-01-01)
Recycled polymer matrix composites reinforced with wood flour can be a viable alternative for the replacement of wood and virgin polymers in materials used in floors, door frames, windows and external cladding. The objective ...
Preparation and characterization of porous microfiltration membranes by using tailor-made propylene/1-octadecene copolymers
(ELSEVIER SCIENCE BV, 2008-08-15)
Tailor-made isotactic polypropylene (iPP) and propylene/1-octadecene (CiPP-OD) copolymers synthesized via
a metallocene catalyst were used for membrane preparation by the thermally induced phase separation (TIPS)
process. ...
Studies of lignin as reinforcement for plastics composites
(2016-03-23)
The growing environmental concerns and depletion of fossil fuels resulted in an increased interest in environmentally friendly materials based on natural polymers. Efforts are being made to introduce the lignin in plastic ...
Preparation of a milk spoilage indicator adsorbed to a modified polypropylene film as an attempt to build a smart packaging
(Elsevier, 2014-09)
A colorimetric sensor of milk spoilage was built from adsorption of methylene blue (MB) onto a modified polypropylene film (PP). First, acrylic acid (AA) was grafted onto PP surface by photograft polymerization reaction, ...
Long-chain branched polypropylene obtained using an epoxy resin as crosslinking agent
(Springer, 2017-06-26)
A reaction between a linear polypropylene functionalized with maleic anhydride (PPg) and epoxy resin (bisphenol A diglycidyl ether) was carried out on the molten state to generate long-chain branches (LCB) in the molecular ...
The effects of specimen size and testing conditions on fracture toughness evaluation of polypropylene homopolymer
(John Wiley & Sons Inc, 2007-04-07)
The results of an experimental test program performed to investigate the influenceof specimen dimensions and testing rate conditions on room temperature fracturetoughness of PP homopolymer are presented. The material ...
Influence of talc morphology on the mechanical properties of talc filled polypropylene
(Springer, 2013-04-30)
Injected polypropylene (PP)/talc composites were studied to evaluate the influence of different talc morphologies on their final mechanical properties. Talc genesis is responsible for type and content of associated minerals, ...
Polypropylene/clay nanocomposites produced by SCORIM: deformation and fracture properties
(Assoc Mechanical Engineers Technicians Slovenia, 2013-10)
The effect of distinct morphologies induced by shear controlled orientation in injection molding (SCORIM) in the mechanical and fracture performance of polypropylene (PP) and PP/nanoclay mouldings is examined in this work. ...
Fracture and failure behavior of jute fabric reinforced polypropylene. Effect of the interface modification
(Smithers Information Ltd, 2006-12)
The tensile fracture and failure behaviour of jute cloth (25 wt.%) reinforced polypropylene (PP) composites were studied as a function of certain interface modification procedures. The latter covered esterification of the ...
