Acrylic embedment

The process is used for preserving specimens, encapsulating electronics, and making decorative items such as trophies (deal toys) and jewelry.

In the early 1940s, Armand G. Winfield was interested in preserving biological and geological specimens.

[1][2][3] The process starts with two basic ingredients, an acrylic resin powder polymer and clear liquid monomer.

There, heat cures and pressure (exceeding 12 atmospheres) compresses the air bubbles to completely harden the embedment.

If flaws or any other defects are detected, the part is returned for additional finishing or rejected for recycling.

This entire procedure makes the result more expensive but because of its glossy look an acrylic embedment is very much in demand.

Because of the high amount of technical knowledge required, the total number of manufacturers remains small.
