Key Documents & Design Files

Overview

The dihydrate form of calcium sulfate used in low temperature thermoset plastic and specialty cement applications. Often used as a flame-retarding filler when processed at room temperature.

Main Features

Terra Alba No. 1is a dihydrate form of calcium sulfate produced by fine grinding and air-separating high-purity, white gypsum containing 20% water of crystallization. It releases combined water as it is heated above 50°C, releasing 75% of water as temperatures reach 180°C (only when temperatures exceed 400°C is water totally removed). USG Terra Alba No. 1:

  • Can be used as a flame-retarding filler when processed at room temperature
  • Contributes to desired expansion, green strength and controlled set in specialty cement applications
  • Is a relatively soft material (2-3 Mohs scale hardness) contributing to minimal wear on equipment.
