Why dispensing valves degrade?
There are various reasons why dispensing valve degrade after a working period. However, the most popular reason is being exposure to chemical for a long time, especially metal filtered adhesive/ thermal paste/ solder paste. To solve this problem, wetted parts of valve must be designed with suitable materials. For example, our GV-525UP.
Why use Teflon for wetting part of dispensing tube and tips?
PTFE can withstand temperatures as low as -450°F and as high as 500°F. Liquids roll off the material, and it doesn’t react to chemicals. It’s simple to clean and commonly used in medical applications for its biocompatibility (compatibility with the human body). As a result, PTFE is widely used for dispensing tube and tips.
