Brief: 
3-D Elastic packing screened polyolefin and polyamide several corrosion, temperature resistance, aging of high-quality varieties, mixed with hydrophilic, adsorption, thermal oxide and other additives, using a special drawing, yarn hair system process, the yarn interspersed fixed in the center of the rope corrosion-resistant, high strength, due to the excellent selection and formulation process, rigid moderate, the yarn was 3-D evenly radiation conditions, made the hang-3- D Elastic packing monomer filler in the effective area can stretch 3-D full uniform covered, so that gas, water, biofilm is fully mixed infiltration exchange exposure, biofilms not only evenly implantation in each of filaments on the bar, to maintain good activity and gap variability, and to get greater and greater than the surface area during operation, but also for a good metabolism, this phenomenon is the current characteristics and other filler match. 
Uses: 
Widely used in biological contact oxidation pond, hydrolysis acidification pool for Biological packing. 
Performance characteristics: 
3-D Elastic packing filler compared with the rigid class cellular porosity variability, it is not clogged; compared with soft fillers, long material life, stick connecting group; compared with Semi-soft packing, large surface area, hanging Film rapid, low cost. Thus, the filler can be confirmed, following a variety of rigid fillers, fourth-generation High efficient energy-saving new packing soft fillers and Semi-soft packing after.
