Sanlo is a professional floating ball factory that integrates production, research and development, and design. We have engineers with 30 years of experience in floating ball production, and our workers have over 20 years of experience in producing floating balls. As customer application demands increase, some clients require float balls for use in harsh working environments involving strong acids, strong alkalis, high temperatures, and high pressures. To meet and assist our customers in solving the problems they encounter, Sanlo has been continuously searching for materials that can meet their requirements. This 48*50*20 PVDF Float Ball for Strong Acids and Bases, after repeated testing, successfully meets the customer's requirements for corrosion resistance in high-temperature and high-pressure environments, and its service life meets customer expectations. Therefore, our company focuses on promoting this product to our vast customer base. For applications that require a very specific working environment and where stainless steel materials cannot meet the requirements, this PVDF float ball can fulfill the needs.
Product Features
With a specific gravity of 0.8, this durable 48*50*20 PVDF Float Ball for Strong Acids and Bases can withstand temperatures below 200 degrees Celsius, exhibits corrosion resistance and resistance to strong acids and alkalis, can withstand a pressure of 2MPa, and has a milky white color throughout, making it very aesthetically pleasing.
PVDF is relatively rare as a raw material in floating balls, as most floating balls are made of stainless steel, NBR, slightly higher-grade titanium, Monel, and so on. Although PVDF floating balls are relatively expensive, their performance under special working conditions is indeed excellent. This is why many customers insist on using this material despite its high cost.
