The GYLON® Style 3522 material is made of 100% pure PTFE with no fillers or additives, making the material ideal for the most demanding, high purity requirements. Industries such as food, pharmaceutical, semi-conductor, recognize the uniformity of GYLON® 3522 that makes it an ideal gasket choice for those critical applications that cannot risk process contamination or premature failure.
CHALLENGES FACED BY CUSTOMER
The previous PTFE valve diaphragms were blistering from SIP cleaning between product runs and maintenance. This was causing premature failure of the diaphragms and bacteria build-up in between layers of the PTFE which was leading to costly downtime and potential product recalls.
EQUIPMENT OPERATING CONDITIONS
- Temperature- 300° F (148°C)
- Media- cleaning agents and dairy products
- Pressure- 145 psi.
SOLUTION AND BENEFITS
Garlock made a diaphragm from GYLON® 3522 which did not blister under the operating conditions; this led to less downtime and the parts lasted over 300k cycles without being changed. The unique structure of GYLON® 3522 reduces the amount of voids in the material and extends the flex life. GYLON® 3522 is 3-A certified.
The customer experienced great success with this solution and extended the service life of their equipment.
