Stair Step Ring Filler Made of PP MaterialThe side ends are reinforced with flanges, which not only enhance the mechanical strength of the filling ring but also increase the directional probability during filling due to the disruption of the filling structure's symmetry. Additionally, the influence of the flanges causes the contact between filling ring gaps during stacking to shift from primarily linear to predominantly point contact.

PP step ring packingThe internal structure of the rings is similar to plastic Baer rings, and they come in both Chinese character and cross patterns. Our company's step rings are available in single and double-layer designs. Materials include plastic step ring fillers (PP, PVDF, PPS, RPP, PTFE, CPVC, etc.).
