Description
Rigid foam ASTI-OP 300, 0.865 kg is a lightweight, easy-to-machine material for precise thermoforming models and cosmetic covers in prosthetics. It is designed for orthopedic technicians, model makers and workshops that need a dimensionally stable base with a smooth surface. Thanks to its excellent sandability, the foam can be shaped efficiently, delivering a precise fit and a professional finish for everyday workshop use.
With rigid foam ASTI-OP 300, 0.865 kg, you can create stable models and covers without adding unnecessary weight. The material is designed for controlled foaming, supporting reproducible results in model making. A practical workshop advantage: the foam is very easy to sand, allowing contours, transitions and edges to be finished precisely—a decisive benefit when a smooth surface is essential for subsequent work steps.
Typical applications for rigid foam ASTI-OP 300, 0.865 kg include thermoforming models and the manufacture of cosmetic covers for prosthetics. It helps reduce common challenges such as time-consuming reworking and uneven surfaces. ASTI-B is used as the B component during processing, so you can work with a coordinated system and structure your manufacturing processes clearly.
