What do you mean by plastination?
Plastination is a technique or process used in anatomy to preserve bodies or body parts, first developed by Gunther von Hagens in 1977. The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay, and even retain most properties of the original sample.

What chemicals are used in plastination?
The chemicals used in polyester plastination include fixatives (if necessary), acetone, methylene chloride (if necessary) and polyester resin. The basic steps of polyester plastination include prepa- ration of the specimen, fixation (if necessary), slicing, dehydration, impregnation and curing.
When did plastination begin?
1977
Plastination is an innovative method of conserving anatomical specimens, where all bodily fluids are exchanged with a polymer, which can be hardened. Plastination was invented by Dr Gunther von Hagens in 1977 and he and his team have further developed the process since then.
Who invented plastination?
Gunther von Hagens
Plastination/Inventors
Von Hagens invented the plastination technique in 1977 while working at Heidelberg University in Heidelberg, Germany. Von Hagens’ plastination technique preserves real bodies and tissues by the removal of the fluid and replacement with resin. Body Worlds features three-dimensional, plastinated human bodies.
Why was plastination created?
Plastination is a technique for preserving tissues, organs, and whole bodies for medical purposes and public display. Gunther von Hagens invented a form of the method in 1977 at Heidelberg University in Heidelberg, Germany, after he observed medical students struggle working with cadavers that quickly decomposed.
Who created body world?
von Hagens
After years of research and small-scale presentations of his work, von Hagens created Body Worlds, or Körperwelten in German. The attraction, which has been viewed by greater than 25 million people, has spread the study of anatomy into the public realm, making it possible for many to see inside an actual human body.
What is plasticization and why is it dangerous?
Plasticization also tends to lead to a loss of mechanical strength and this can result in total membrane failure due to the collapse of the support structure. Plasticization can be caused by a number of gases that are readily sorbed within the membrane including carbon dioxide, water and a range of linear hydrocarbons and aromatics.
What are the methods of plasticization of polymers?
There are two main principal methods exist for plasticization – Internal Plasticization and External Plasticization. A polymer can be internally plasticized by chemically modifying the polymer or monomer so that the flexibility is increased.
What is the effect of temperature on plasticization?
Conversely, higher temperatures can lead to accelerated ageing in all systems. Plasticization is a technique used for modifying and improving flexibility, distensibility, processability, and properties of biopolymers intended for suitable applications by lowering the glass transition (second order) temperature (Tg).
What is plasticization of a resin?
Plasticization of a resin or plastic can be accomplished by external or internal means. The examples given above are external, which refers to the addition to a resin of a plasticizer that is usually a liquid ranging in molecular weight from under 300 to greater than 10,000.
