2. The material is dense, the water absorption rate is low to zero, the surface finish is extremely high, and the friction is extremely small, so the material residue is extremely small.
3. Very inert chemical stability, corrosion resistance, acid and alkali resistance, and high temperature resistance.
4. The thermal expansion coefficient is extremely small, the piston clearance fit is better, the filling accuracy is higher, and online cleaning and sterilization can be realized. 5. Super hard, wear-resistant, extremely small particle release, and long service life.
