Cenospheres are low density, very useful in the manufacturing of plastics, sealants, automotive parts and under coatings, and in applications as diverse as aerospace, sound dampening, and putties where lightweight material is key. Using lower density materials in the manufacturing of construction materials is becoming more popular. The lightweight, yet strong nature of the cenospheres adds versatility, strength, lowered shrinkage and sag levels.
