 SINSTON-M401 Improved PTFE gasket
Modified PTFE Gasket
Modified PTFE gasket are in order to meet the needs of customers
to different working conditions, and reduce the cost.
Walyman
research and design the modified PTFE gaskets.
Benefits
> Reduced creep relaxation;
> Chemical resistant;
> Cost saving;
> Tighter seal.
>Modified PTFE gaskets improved performance over conventional
PTFE, Reduced product loss and emissions. Excellent bolt torque
retention, unique manufacturing process minimizes cold flow
problems typical of skived and expanded PTFE Sheets. Withstands
a wide range of chemicals for extended service life in a wide
variety of applications.
