Material Introduction

Spring Seal/ spring energized seal/ Variseal is a U-type Teflon built-in special spring high-performance seal with appropriate spring force plus system fluid pressure to eject the sealing lip (face) Gently press the sealed metal surface to create a very good sealing effect. The actuating effect of the spring overcomes the slight eccentricity of the metal mating surface and the wear of the sealing lip while maintaining the desired sealing performance. The special seals developed for high temperature corrosion, difficult lubrication and low friction applications. The combination of different Teflon composites, advanced engineering plastics and corrosion resistant metal springs can meet the increasingly stringent industrial requirements. The diversity of needs.

PTFE pan plug material storage and use guide

1. In the case of powder, the powder may agglomerate during vibration or high temperature during transportation. The material may be cooled before use and sieved with a sieve or pulverized with a loose machine/pulverizer for normal use.

2. The granulation material will not cause agglomeration. It is recommended to use a stainless steel spoon to dip.

3. The storage temperature is recommended to be in the range of 20-25 ° C and humidity 25 - 55%.

4. If the material is not used after opening, tie the double-layer plastic bag with a tie and change the cover to avoid moisture absorption or contamination.

5. In the correct storage environment, material storage time can be almost unlimited and will not expire.

6. During the production process, workers are advised to wear adequate labor protection (masks, gloves, etc.).

7. For more information on safe use, please contact your Cylex sales staff.
