Advantages:

(1) Reduced Raw Materials Cost
(2) Improved Flowability
(3) Reduced Resin Demand
(4) Improved Insulation Values
(5) Reduced End Product Weight
(6) Resistant to Resin Absorption

Features: They have excellent fluidity as well as sound,electric and heat insulation,cenospheres are a filler used to replace minerals and resins where the benefits may be as diverse as weight reduction,improved thermal insulation ,reduced shrinkage ,improved fire resistance or simply easier application.
