Which is better, PP fume hood or all-steel fume hood?
        all-steel fume hoods are relatively common now. They are mainly due to the greater flexibility in transportation and installation of assembled parts. The overall color is optional. For larger laboratory projects, the corresponding color matching can be selected according to the overall style. The fire and explosion resistance is relatively good, and the price is relatively low.
      In recent years, due to the development of raw materials and processing applications,  PP fume hoods have good prices, good quality, and good choices. They are more resistant to acid, alkali and corrosion. Since the whole unit is made of welding, it is generally shipped in one piece. It is easy to be damaged during transportation and installation. PP general The material of the fume hood is polypropylene. It is generally dangerous to have fire or high temperature in laboratory experiments. However, some fume hoods are added with flame retardant materials to avoid danger. Secondly, the hardness of PP fume hoods is not high and the durability is not good. It will deform itself over time. When choosing, choose a keel or thickened material.
