VF shapes are produced from corresponding level refractory fibre mixture through vaccum forming.

VF shapes without burning are free shear and bending. They are the ideal energy- efficient insulation materials for furnaces, pipings and other equipments.

Supporting surface hardening or completely hardening to every level VF shapes according to customers' demand.
