Description

HYPOL EMULSION, developed by Hampshire Chemical Company, is a specialized liquid isocyanate-capped polyurethane prepolymer. It is engineered for the creation of hydrophilic polyurethane foams and is particularly suited for biotechnological applications, such as cell immobilization.

Key Features

  • Rapid Wet Out: This emulsion is characterized by its rapid surface wetting properties, achieving wet out in less than 30 seconds, and often in under 5 seconds.
  • Foam Properties: The resulting foams exhibit densities ranging from 4.0 to 9.5 lbs/ft³, with dry tensile strengths reaching up to 46.3 psi and elongation capacities up to 480%.

Composition

The formulation includes:

  • Polyether Polyol with a high ethylene oxide content.
  • Isocyanate components, such as methylene diphenyl diisocyanate.
  • Silicone Glycol Copolymer Liquid Surfactant used in small proportions.

Applications

HYPOL EMULSION is ideal for producing hydrophilic foams used in absorptive devices like clean room wipes. In biotechnological settings, it effectively immobilizes cells such as Escherichia coli, enhancing biocatalysis processes like the conversion of ammonium fumarate to l-aspartic acid. This application benefits from increased production rates at higher temperatures and a broad pH range.

Handling Guidelines

Proper handling is crucial due to its sensitivity to shear and pressure. Key guidelines include:

  • Avoiding high-pressure pipelines and ensuring thorough drying of pump components to prevent water contamination.
  • Designing systems to prevent backflow of dilution water into emulsion storage.
  • Implementing appropriate filtration methods, avoiding mesh sizes below 500 μ, and refraining from in-line filtration and agitation before use.

These measures help maintain the stability of the emulsion and prevent unwanted gel formation, ensuring optimal performance in its intended applications.
