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.
