Heavy-duty chemical protection suit with an ultra-large screen RHF-ⅠJZ-2

【Product Description】

The heavy-duty chemical protective suit is the protective clothing worn by rescue personnel when entering the accident site contaminated by chemical substances or corrosive items such as strong acids and strong alkalis for operations. This suit is made of high-strength flame-retardant anti-acid and alkali fabric in strict accordance with XF770-2008 "Firefighter Chemical Protective Clothing". It not only has the ability to resist strong acids and strong alkalis, but also possesses excellent flame-retardant and strength properties. This suit can be used in industries such as firefighting, petroleum, and chemical engineering.
