Product Description

What Is The Best Advantages For Juntai 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,Juntai design a very good formula which be 3 to 5 years longer life and lower resistant, high deformation resistance and elasticity

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
