PVDF Level Indicator DN15-50

PVDF (Polyvinylidene Fluoride) and FRPP (Fiberglass Reinforced Polypropylene) are materials that can be used to make level indicators.
PVDF level indicators are made of polyvinylidene fluoride, which is a strong, tough and abrasion resistant thermoplastic material. PVDF level indicators are often used in corrosive chemical processing, pharmaceutical production and water treatment because of its excellent chemical resistance and high temperature resistance.
FRPP level indicators are made of fiberglass reinforced polypropylene, which is a composite material made of polypropylene reinforced with fiberglass. The material is strong, durable, and resistant to corrosion and high temperatures. FRPP level indicators are often used in industrial and commercial applications where these properties are required, such as in chemical and petrochemical plants.
It's worth noting that while PVDF and FRPP both have high chemical resistance and temperature resistance, PVDF is a more corrosion resistant material and it is more appropriate to use in more aggressive chemical environments. On the other hand, FRPP can be relatively more affordable option for less demanding applications
The choice of material for level indicators will be based on the specific application, environment and the chemical resistance required.
