What Is The Best Advantages For Aquasust Smart Disc Diffuser ?
In order to make long life of the Disc diffuser, the most important is the good fomula of EPDM (Ethylene-Propylene-Diene Monomer).
After 10 years development,Aquasust design a very good formula which be 3 to 5 years longer life and lower resistant, high deformation resistance and elasticity

About The Aquasust Smart Disc Diffuser Core Material
1. Import High quality EDPM 8600 from Exxon Mobil USA
2. High quality Carbon which from Cabot from USA
Aquasust Has The Most Advanced Production Equipment
Aquasust are a production-oriented factory, and advanced equipment is the basis for quality assurance. Try to use the control of the device to reduce the chance of human error. Use equipment to improve production efficiency and reduce labor intensity.
How Does A Perfect Disc Diffuser Come Out?
Development of Membrane Materials
1.Exxon Molecular Weight "Bimodal" Distribution EPDM Original Gum
2.DMS company controllable long chain branching technology EPDM
3.Double peroxide vulcanization crosslinking technology :
The peroxy system forms carbon-carbon crosslinks, which have short crosslinks, high rigidity, high stability, low compression set, and high resilience, but also have the
disadvantages of low tear strength and elongation. The double peroxycuring system improves tear strength and elongation.
The increase in strength makes it possible to increase the number of pores per unit area:
1.The number of holes is increased to: 25-30 holes/cm2
2.Tubular aeration membrane, 32,000 holes per meter
3.The pores are 30% smaller, and the ventilation resistance is also 20% smaller
