Plastic Rosette Ring – Multiple Materials for Chemical Stability

Plastic rosette ring, a type of typical random packing, is made of various plastic materials, has excellent corrosion and chemical resistance performance. it can be used in different temperature conditions for excellent filtering applications. The plastic teller rosette ring, is composed of several small rings in radial distribution and a big ring. The rings are sintered together to maintain high liquid holding capacity. It has similar structure with plastic teller rosette ring, which has a bit complex structure than rosette ring.
