Plasticized animal specimens are water and local fat in animal remains or animals or structural organs soaked in formalin, which are replaced by active plastics, silicone rubber and polymeric resin. After vacuum treatment, the structural organs and overall shape of animals still adhere to their pre-existing forms. Because the specimen contains no water, it can be preserved for a long time. Let's take a look at how to make plasticized animal specimens.

The proces of making plasticize animal specimens is mainly divided into four steps:

(1) fastness: use 5%- 10% formalin, and dehydration and drying should be avoided in this process;

(2) Dehydration: acetone is commonly used for dehydration;

(3) Forced rubber infiltration: in a vacuum state, acetone in structural organs is forcibly replaced by active plastics, rubber and other materials;

(4) Hardening: also known as curing, the specimen is firmly shaped with tools such as wooden sticks and iron wires, and then the curing agent is repeatedly sprayed on the specimen for curing, and finally it is shaped.
