PMMA (UV), or Acrylic was one of the first synthetic materials of the 20th century as an alternative to glass, in airplanes, in automobiles, and in ships.

PMMA is better known as acrylic glass or plexiglass.

Because PMMA is UV active, it will glow in a black light/UV light, or in a disco, which makes it a popular choice with customers.

 

Given that PTFE does not conduct electricity, it can be worn during surgical operations, X-Rays, CT scans, or MRIs.

Like PTFE and PMFK, PMMA is not magnetic.

Stretching jewelry and corkscrews are available in different colors for PMFK, and thanks to their hardness and light weight, they are well suited for stretching a piercing.
