PTFE Diaphragms Manufacturer and Supplier
PolyTetraFluoroEthylene (PTFE) is a form of thermoplastic resin that is resistant to practically everything. Hence, it is one of the best materials for diaphragm because of its chemical stability and resistance.
PTFE diaphragms have been one of the most successful components that have lead to a breakthrough in the pump industry• They have been widely produced and are extremely successful in oil chemical industry, coal industries, paper making, weaving, food and beverage industry, pharmaceuticals and bio-processing industry.
AVAILABLE SIZES OF PTFE DIAPHRAGM
Based on the difference in how the material handles other chemicals during actuation, existing actuators need to be improved. Hence, the following sizes were manufactured in order to suit the requirements of different buyers:
1) 1 inch PTFE diaphragm
2)1.5 inch PTFE diaphragm
3) 2 inch PTFE diaphragm
4) 3 inch PTFE diaphragm
APPLICATIONS OR USES OF PTFE DIAPHRAGM
The PTFE diaphragm has been widely accepted by all the buyers because of its stability and resistance. However, the most common consumers of the diaphragm are:
• Food processing industry
• Sanitary application industry
• Chemicals and refineries
• Electronic industry
• Water and waste processing industries
• Pharmaceutical industry
• Chemical production industry
PROPERTIES OF PTFE DIAPHRAGM
The major properties of PTFE diaphragm are:
• It is extremely chemically resistant to most of the substances. Hence, it is often used with heptanes and methyl chloride.
• It is completely resistant towards steam.
• It is not a complete elastomer and has a clod flow issues that can result in leaking sometimes.
• The cost of PTFE diaphragm is relatively higher than the rest of materials used for making a diaphragm.
BENEFITS OF PTFE DIAPHRAGM OVER OTHER MATERIALS
The benefits of PTFE diaphragm over other diaphragm materials are:
• Extreme chemical resistance
• Extreme heat resistance
• Extreme steam resistance
WEAKNESSES OF PTFE DIAPHRAGM
Some of the weaknesses faced by PTFE diaphragms are:
• It has cold flow issues that can result in leaking.
• It is more expensive than the other diaphragms of other materials
• It is hard to work with during maintenance.
OPERATING TEMPERATURE RANGE
The recommended temperature range for PTFE diaphragms are (39°F to 500°F) or (4°C to 260°C)
