CHAPTER 2 | PROCESS SETTINGS
Density Modified Formulations
Gravi-Tech™ polymer-metal composites are high-density materials developed as thermoplastic-
based alternatives to metals.
Solvent
Solvents soften surfaces of plastic (plastic
must be soluble)—best for amorphous or
low crystalline plastics, such as ABS, acrylic,
cellulosic, PC, PS, PPO, and vinyls.
