Special design with composite material, the light blue part is made in food grade TPE  (Thermoplastic Elastomer), which can provide good seal performance.

 

About TPE

Thermoplastic elastomers (TPEs) combine the good processing properties of plastics with the elastomer properties that are so important for product developers and designers. Thermoplastic elastomers consist of thermoplastic end blocks and an elastic midblock. As regards their structure and behaviour, they belong to a material class that is positioned between plastics (thermoplastics) and rubber (elastomer) and have gradually been developed into a material class of their own.

 

They enhance products and enable processors to position their products ahead of those of their competitors. In addition, TPEs also fulfil technical functions that have up to now only been available with elastomers. The use of TPEs does not only offer a range of product advantages but also has significant commercial benefits for processors. Similar to thermoplastics, TPEs become plastic when heated and elastic when cooled down again. In elastomers, this behaviour is due to chemical cross-linking. In TPEs, it is the result of physical cross-linking, and any changes in behaviour caused by heating are reversible. When the material is cooled down, new cross-links are established, which bond the elastic blocks into rigid three-dimensional networks. This means that TPEs show elastic properties that are similar to those of elastomers, while allowing for repeat deformation and recovery as known from thermoplastics. Thermoplastic elastomers are thus free-flowing and formable

For ozone sterilizing, the sterilization rate depends on the equation concentration of ozone and contacting time, higher concentration, shorter contacting time.

The ozonation process can be various, such as Venturi tube, aeration tank, mixing pump or combined device.

For UV sterilizing, the sterilization rate depends on the dosage, here, the  related elements will be : flow rate,  lamp power, lighting time and distance.

The UV-ozone combined sterilizing solution can reach better effects than single process.

The ozone sterilization is quick and safe. When the ozone concentrations get to a certain percent, it kills the virus and germ immediately, then breaks up to oxygen, bring no secondary pollution. Compare with the other solution, ozone can diffuse quickly without shadow, operated easily and consume low energy.

The ozone has popular application and important value in the field of air purge, sterilization, deodorization, drinking water cleansing, food processing, dining service, medical etc.
