Altair® I-300

A cross-linked continuous cast acrylic sheet with enhanced thermoforming properties.

Opaque and Marbleized Sheet

Altair® I-300 has a special molecular structure, which provides superior product and performance properties. It is chemical, stain, UV and weather resistant in addition to having a durable, high gloss surface. Plumbingware and spa manufacturers have used Altair® I-300 as the surface material on their premium modular tub/shower, whirlpool and spa units for over 20 years. It is available in a variety of colors, including many stunning marbleized patterns. Aristech Acrylics® can also custom match and maintain color consistency from production run to production run.

The superior product properties of Altair® I-300 offers plumbing ware and spa manufacturers a durable surface with long-lasting aesthetics. The sheet is easily thermoformed and is so forgiving that is can be reheated and reformed.

Manufacturers have found Altair® I-300 can streamline the production process, cut mold costs, and shorten production time compared to traditional FRP units. Designers like the freedom of its superior thermoforming properties that our vast array of colors allow. Homeowners appreciate its stain and mildew resistance as well as its ease of cleaning. Just wiping it down with a mild detergent is all that's required to make it look like new. The brilliant, high-gloss colors are unique because the color is permanently cast throughout the product, not just on the surface. Colors don't fade, even after years of use and repeated cleaning with mild liquid cleansers. In fact, Altair® I-300 is non-porous and repels filth and grime, meaning it is hygienic and safe for the whole family to use.
