Optimizing the Properties of Polyether Based Polyurethane Foam

Abstract

Effect of different chemicals and additives used in producing polyester foam was investigated. Reference samples were produced from polyol, toluene di isocyanate (TDI), amine stannous octoate distil water, and silicone oil using laboratory mix formulation based on 500 g polyether based polyol. Other samples were produced by consecutively varying the content of all the additives with the exception of polyol. Standard sample dimensions for density test, indentation test, compression set test, tensile strength and elongation tests were produced from the samples. The various tests were carried out on the samples using the ASTM-D3574 standards. It was observed that the degree of indentation affects the value of indentation hardness and increasing the percentage content of TDI results in acceptable compression set value for the polyester samples. It was concluded that Holding all other parameters constant, reducing the water content and increasing the TDI content will yield polyester foam of optimum properties.

Enhancing Strength and Sustainability: Evaluating Glass and Basalt Fiber-Reinforced Biopolyamide as Alternatives for Petroleum-Based Polyamide Composite

“…They are produced as rovings, chopped strands, yarns, fabrics, and mats. Each type of glass fiber has unique properties, thus providing the possibility of various applications [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

Studies on thermoset blend of bismaleimide having multiple swivel groups and biscyanate ester

“…In the quest for the replacement of metals in demanding applications in defence and aerospace, together with excellent strength and light weight urged chemists to develop different matrix resin systems and a wide variety of both inorganic and organic fibres with broad spectrum of tailorable properties. 1,2 Hence development of composites having applications in various engineering fields along with good thermal stability and having ability to serve continuously at high temperature (above 250°C) is continuing. 3,4 Still there exists heavy demand for resin systems having lower cure temperature but higher thermal stability or degradation temperature.…”

Recycling effects on the bending, rheological, and structural properties of glass fiber-reinforced isotactic polypropylene composites

“…19,20 The use of glass fibers as reinforcement for many thermoplastics, especially the use of E-glass for relatively strong and lightweight plastic composites, has been reported. [21][22][23] They have applications in areas such as home and furniture, boats and marine, aviation and aerospace, automotive components, etc. 24 Recycling is a process aimed at recovering reusable parts and processable materials.…”
