Reversible hydrocolloid: The standard of excellence
The Journal of Prosthetic Dentistry, 1988Reversible hydrocolloid is the oldest elastic dental impression material and, with the appropriate methodology, the advantages outweigh the disadvantages. Skill, care, and comprehension of the physical properties of the materials ensure success.

Lubricity of dilute solutions of hydrocolloids
Journal of Pharmaceutical Sciences, 1967To determine relative lubricity of hydrocolloids at low viscosities, the friction values of dilute solutions of seven hydrocolloids were measured with the lubrimeter. At very low viscosities, hydrocolloids impart no lubricity to water. A certain consistency appears to be a prerequisite for hydrocolloid dispersions to be effective as lubricants, except ...

Emulsification properties of hydrocolloids
Polymers for Advanced Technologies, 2001Water soluble/dispersible polysaccharides, termed hydrocolloids or gums, are known as viscosity builders and/or gelling agents in aqueous systems. Technologists call them stabilizers, since they can improve long-term stability in systems consisting of water and oil.

Hydrocolloid coating of cheeses
Food Hydrocolloids, 2000Abstract Semi-hard and dry white brined cheeses were coated with hydrocolloid films based on κ-carrageenan, alginate and gellan. The cheeses were immersed in the gum solution followed by cross-linking of the gum solution to produce a coated product. A few coating films were then dried by airflow to induce better adherence of the coating to the coated

Boxing impressions with irreversible hydrocolloid
The Journal of Prosthetic Dentistry, 1985A boxing method that uses irreversible hydrocolloid for boxing final impressions made with four different final impression materials was described. The boxing material separated from the impression in one piece with all impression materials. No separation media was required.

Role of hydrocolloids in wound management
British Journal of Nursing, 1993This article describes the actions of hydrocolloid dressings and the type of wounds for which they are most suitable. The range of hydrocolloid products is reviewed along with their individual advantages and disadvantages.

A cellular solid is an interconnected network of solid struts or plates that forms the edges and faces of cells (Gibson and Ashby, 1988). Cellular materials such as cork, first mentioned for use as bungs in wine bottles in Roman times, have been used for centuries. Recently, different artificial cellular solids have been developed.

Agricultural uses of hydrocolloids
1997The release of agricultural chemicals (including pesticides) can be controlled by the use of polymers. These polymers control the rate of delivery, the mobility and the length of time for which the component is considered effective. The greatest advantage of controlled-release formulations is that less chemical is used during a given time interval ...
