PTFE Coated Fibreglass Fabric – Comprising the coat which is PTFE and the substrate-Fibreglass Fabric adhered together through a coating system. PTFE (Polytetrafluoroethylene), when coated on fiberglass fabric, makes it a high tensile membrane.
PTFE Coated Fibreglass Fabric – Comprising the coat which is PTFE and the substrate-Fibreglass Fabric adhered together through a coating system. PTFE (Polytetrafluoroethylene), when coated on fiberglass fabric, makes it a high tensile membrane. PTFE makes the fabric thermally stable, chemical resistant, insoluble in almost all solvents, UV resistant, flexible and does not break when subject to stress, high resilience characteristics, lowest friction coefficients, dielectric constant, nonflammable, waterproof and excellent insulator. Whereas Fibreglass maintains the structural function of the safety spray shield. Fiberglass has high modulus elasticity and high tensile strength.
We take utmost care in choosing the fabric for the flange guards and ptfe shield so that there are no pin holes which eventually may lead to accidents. Coating thickness is checked so that ptfe flange guard can perform in extreme conditions for extended periods. We use Kevlar threads, to assemble our flange shield, which are strongest and decomposes at 800 degrees Fahrenheit or 426 degrees Celsius. Kevlar threads have very little stretch and are 2-3 times stronger than nylon or polyester. Kevlar threads are only available in Yellow color and are very very expensive. They also have a very high maximum operating temperature.
All our flange guards are made of multiple layers of PTFE Coated fiberglass fabric with an inner scrim. Saifex PTFE Flange Guard
The inner scrim helps the safety spray shields in holding on to the flanges. Braided PTFE coated ropes are used on the safety shield which are fire retardant and do not decompose in extreme conditions. Cotton or nylon ropes will not last under these extreme conditions and eventually compromise the safety of the guard. Velcro is provided on the extreme ends of the safety spray shields giving it the second fastening system.
The Spray Guards are available for the following:
PTFE Flange Shield
PTFE Ball Valve Shield
PTFE Butterfly Valve Shield
PTFE Expansion Joints Shield

Polypropylene is low density thermoplastic and enjoys a high melting point of 160 degrees Celsius and above.It has a operating temperature of 125 degree Celsius.
Successful Stainless steel creation goes back to 1913 when Harry Brearley created a steel with 12.8% chromium and a carbon percentage of merely 24 percent. Stainless steel was made with the sole purpose of creating a weather and acid resistant steel.
