High temperature resistant reflective aluminum RFR rayon reflective shield is sewn with DuPont Kevlar 4-wire fire-retardant thread with high tensile force and flame retardancy. The outer PFR rayon reflective aluminum can reflect heat flow, which has the effects of fire retardation and heat flow reflection, and can reflect 96% of heat flow; Middle leather provides further insulation. Equipped with hand shield, ordinary welding gloves can reflect heat flow. Practical, efficient, convenient and fast
