LONG-TERMMATERIAL TESTING
Reducing environmental impact does not mean compromising material lifespan.
Uniform samples of different resin formulations are observed under the same conditions. Transparency, colour, and surface condition are recorded on Days 0, 7, 14, and 28.
Natural-light exposure tests compare yellowing resistance, transparency retention, and long-term stability.
