BIOFLON GRADE GP
Bioflon GP is the ‘General Purpose’ grade, for use in all applications where fluids or gases are being conveyed which do not generate a risk of static charge development (see Bioflex Grade “AS”).
MATERIALS & SPECIFICATIONS
Bioflon GP has a virgin PTFE liner, manufactured from hose grade PTFE which conforms to the requirements of: FDA 21 CFR 177.1550.
The PTFE Liner is covered by a Grade 304 SS braid, then a Grade 304 SS helical reinforcing wire.
An external cover of blue, EPDM rubber (Grade RC) or clear, platinum cured silicone rubber (Grade SI) is applied over the outside of the construction.
GP & AS GRADE APPROVALS
The full list of approvals and certifications can be found in the Quality Assurance Section
BIOFLON GRADE AS (ANTISTATIC)
Bioflon AS is an essential requirement in applications where there is the risk of an electrostatic charge build-up on the inside surface of the PTFE tube which may then discharge through the tube wall. Media passing through which create such a risk are fluids which have a Conductance of less than 10-8 S/m (Siemens per Metre), or 104 pS/m such as fuels, solvents, freons, some WFI (ultra-pure “Water for Injection”) and non-polar organics which are being transferred at a medium to high flow velocity.
All twin or multi phase media, and any non-mixing media, such as powder in air, or water droplets in steam, in gases or in oil, also colloidal fluids constitute a particular hazard for static charge generation, and always require grade AS.
If in doubt, consult Aflex Hose.
