Application of Hollow Glass Sphere in Epoxy Tooling Board
Epoxy Tooling Board filled with Hollow Glass Sphere has good performance in producing furniture parts、automotive model、architectural model、decoration、sculpture.
Adding different proportional of Hollow Glass Sphere into the original formula, not only can reduce the usage amount of resins, reducing cost, but also can make ideal product density.
The oil absorption rate of Hollow Glass Sphere is much lower than traditional fillers, such as calcium carbonate, which makes resin form the film effectively and enhance the adhesion.
Compared with traditional mineral additives, Hollow Glass Sphere has better fluidity and dispersity, which assure dimensional stability of product, reducing shrink and warpage and enhance toughness and impact strength.
