Heat Chemical Resistant Fiber, PROCON

Characteristics

Procon

  • PROCON® is PPS (Polyphenylene Sulfide) fiber developed by Toyobo.
  • PROCON® fiber has excellent chemical resistance against acids and alkaline media at high temperatures of 150 to 190.
  • PROCON® fiber is not susceptible to hydrolysis at all.
  • PROCON® fiber with trilobal cross section increased its fiber surface for good filtration efficiency.
  • PROCON® is a trademark of TOYOBO in Japan.

Chemical Resistance (Dipping Test) (362KB)
Stability of PROCON® against Hydrolysis (221KB)
Gas Treatment Test (225KB)
Gas Treatment Test (10% O2) (125KB)
Thermal Stability of PROCON® in Air (552KB)

Disposal of used bags

Both PROCON® and P84 filter bags after using can be disposed in house incinerator as main gases generated in combustion are CO, CO2, NOx and Sox, not included toxic ingredient such as HF. Also the residue is very lower.

1.
The Procedure for the combustion gas analysis is conformed to JIS K 7217, temperature 750.
2.
The procedure for the residue after combustion is conformed to the guidance written by Japan Waste Management Association, temperature 600 for 3 hours in air.

Technical Support

The right choice for the appropriate filter media has to be made in conjunction with all flue gas data available. It is necessary to know as precisely as possible parameters like temperature (continuous temp. and peak temp.), oxygen, bromine and nitrogen-dioxide contents.
Toyobo offers a technical support for end users based on long term working experience in filtration as well as on a data base with a lot of installations worldwide.
