Can prevent liquid or fine grain from the joint area to cause permeating or invading inside outside of machines parts.
Drinking Water Certification: We attach great importance to the quality and safety of drinking water. To avoid contamination from raw materials, we independently produce rubber materials formulated for drinking water while ensuring and comprehensively requiring that the quality of the rubber materials must meet the certification conform to the NSF (USA), to the NSF (USA), WRAS (UK), KTW (Germany) and ACS (France)…and so forth.
The height of pressure and the circle change of pressure will affect the life of seal items. The higher pressure the cause of affecting seal items is bigger. Its involving affect the other factors, such as temperature, speed, choice usage of material and the gap between seal items and contact surface. If it appears crack, the whole hydraulic pressure pneumatic component is going to lose effectiveness.
When operating seal items,temperature will change following it, therefore, it is harder to regulate the proper temperature to use seal items.
The following factors will affect the friction between seal items and object's surface. Such as: surface rough degree, surface feature, temperature, pressure, medium, seal items' pattern, seal items material and operating speed.
If seal items'surface is higher rough degree,seal items' moving speed and standing surface pressure and medium temperature will become direct ratio. It will cause damage of seal items.
The best seal pad have commonly hard surface and the inside soft.
Hard surface: can guarantee inside seal property. Inside soft : can maintain a regular flexibility to be able to have the effect of deformation.
