Effect of gasket material size

Effect of gasket material size

a. Effect of gasket thickness: Under the same compression load and the same medium pressure, the leakage rate decreases with the increase of the thickness of the gasket. This is because under the same axial load, the thick gasket has a large amount of compression rebound. Under the condition that the initial sealing condition has been reached, the thick gasket with larger elastic reserve can compensate more than the thin gasket. The relative separation between the sealing surfaces caused by the medium pressure and the large residual compressive stress of the gasket surface, thereby reducing the leakage rate.

Pearl cotton (EPE) environmentally friendly packaging materials

Pearl cotton (EPE) environmentally friendly packaging materials

Polyethylene foamed cotton long and short cross-linked closed-cell structure, also known as EPE pearl cotton, is a new environmentally friendly packaging material. It consists of low density polyethylene glycol by physical foaming to produce a myriad of independent bubbles. It overcomes the shortcomings of common styrofoam, such as fragility, deformation and poor recovery. It has many advantages such as water-proof, moisture-proof, shock-proof, sound-proof, heat-insulating, good plasticity, toughness, reincarnation, environmental protection, strong impact resistance, etc. It also has good chemical resistance. It is an ideal substitute for traditional packaging materials.
