Catalyst-free methods of forming polyurethanes from pentafluorophenyl carbonates

One catalyst-free method of forming a polyurethane comprises forming a first emulsion comprising a first monomer, a surfactant, a water immiscible organic solvent, and water. The first monomer comprises two or more pentafluorophenyl carbonate groups. The first emulsion is combined with an aqueous mixture containing a second monomer comprising two...

Aliphatic Polyester Polyols with Recycled Content for Flexible Polyurethane Foam

Polyurethane formulators continue to develop new applications using INVISTA's TERRIN™ polyols, which are 100% aliphatic polyester polyols with unique structures that contain a minimum of 50% recycled content; some also have renewable content. These polyols offer formulators alternatives that can help achieve the often contradictory objectives of...

Novel Catalyst for Low-Emission Viscoelastic (VE) Foams

Viscoelastic (VE) foams are a type of flexible polyurethane foam which exhibit characteristics of both resiliency and viscosity. VE foams exhibit low resiliency, high viscosity, vibration damping, sound absorption and good texture. These characteristics have led to increased demand for VE foams in products such as high quality pillows, mattresses,...

Improved Viscoelastic Foam Formulation Technology

A continued trend in the manufacture of viscoelastic polyurethane flexible foams is to achieve higher quality and even lower density foams. Past formulation or machine processing limitations can be overcome by new formulation techniques which can reduce the need for multiple, unique polyols and/or isocyanates. This paper will introduce these...

Highly Sophisticated Cell Opener for Viscoelastic Foam

TDI 80 viscoelastic formulations have a tendency toward closed cell structures, which often result in shrinkage. The role of the cell structure - cell fineness and porosity - turns out to be significant for viscoelastic foams relying on the pneumatic as well as the adhesion effect. Therefore, careful control of cell regulation and cell opening are...

Isosorbide, a cyclic, rigid and renewable diol was used as a chain extender in two series of thermoplastic polyurethanes. Isosorbide was used alone or in combination with butane diol to examine the effects on the morphology of polyurethane (PU). Two series of materials were prepared - one with dispersed hard domains in the matrix of...
