Delpowder™
General Series

Asahi Kasei's Delpowder™︎'s General series is a methacrylic resin with fine, spherical particles that are easily dissolved. It is ideal for compounding.

General Series

Small particle size
Ideal for compounds

Delpowder™ is a methacrylic resin formed into spherical beads of a small particle size so that they are easily dissolved. It is added to other resins to give them a glossy finish, and is used as a material for artificial marble and adhesives. We offer a wide range of molecular weights to meet your needs.
