Perla PReexpandida
The perla Pre-expandida FANOSA (pre-expanded pearl) is produced through the primary expansion of small, pure polystyrene grains in a continuous operation system and fed with water vapor under controlled temperature and pressure; these pearls contain fire retardant additives.
According to the needs, a wide array of pearl densities can be obtained through the manufacturing process, resulting in excellent thermal and electrical resistance properties, a lightweight and floating product, shock absorbent, and low water absorption. Due to these properties, the pearls are extensively used to improved heat insulation and to produce a lightweight, highly resistant, low-cost and high-performance concrete and cement mix.

What pearl sizes are available?
Densities ranking from 12.8 up to 50 kg/m3
What are the pearl's main advantages?
Some of the main advantages are its low-cost, lightweight and insulating properties, high-performance on the worksite and its great variety of applications.
How are the polystyrene and concrete mixed?
To mix the polystyrene with the concrete just substitute the aggregate on the mix. Since the pearl tends to float, it is recommended to moisten it a little before adding the rest of the ingredients.
