PTFE - The Optimum Choice For Hose Linings Section from a PTFE Molecule, 16 Angstrom Units long PTFE, or Polytetrafluoroethylene, comprises of longchain molecules of carbon atoms, each linked to two fluorine atoms. The fluorine atoms provide a helical spiral which surrounds the carbon chain and protects it. It is this structure which creates the unique properties for which PTFE is well-known. • Excellent Chemical Resistance PTFE is renowned as the most chemically resistant material known. Only a very few, very unusual substances and conditions can affect it, like Fluorine gas at high temperature...

Bioflex Ultra - The New Product Design from Aflex Hose The World’s Leading Manufacturer of PTFE Flexible Hose Aflex Hose, founded in 1973, pioneered the concept of PTFE lined flexible hose for the transfer of process fluids. Over the years since then, hundreds of thousands of custom-built PTFE Lined hoses have been designed and manufactured by Aflex Hose to cope with the most difficult of operating conditions, and Aflex have continuously developed and expanded their product range having pioneered and introduced Antistatic hose, Polypropylene Braided hose and many other innovations in response...

Bioflex Ultra Hose Design and Comparative Properties Bioflex Ultra Hose Design Options Bioflex Ultra Hose Grades are made up by combining the Design Options, which are defined by 2 letters as shown below, and fully described on the indicated pages. For example, “Bioflex Ultra AS, PB, SG” defines a hose with an Antistatic PTFE liner (AS) and a Polypropylene braid (PB) and an outer “Safegard” (SG) spiral HDPE protection sleeve. PTFE Liner Tube Options - GP (Natural PTFE) and AS (Antistatic PTFE) - Braid Options - TO (Tube Only, No Braid), SS (316 SS Wire), and PB (Polypropylene) - Rubber Cover...

Bioflex Ultra Hose: Special Test Program Bioflex Ultra has been designed to fulfil the most demanding of customer expectations and, as such, has been subjected to a rigorous Accelerated Service Life Testing Programme in comparison with competitive hose products. The ‘Rolling U’ Test. Bioflex Ultra samples were run side by side with competitors’ products, including smoothbore FEP, PTFE or PFA lined Rubber hose products, and also smooth flex products, on a ‘Rolling U’ test rig. The 1” bore samples were “Rolled” at the minimum bend radius and at the maximum working pressure quoted for the competitor’s...

Bioflex Ultra Specifications: Temperatures, Pressures & Flow Rates Temperature vs Pressure Temperature & Maximum Working Pressure Graph for Bioflex Ultra Due to its extremely strong RC & BK Grades construction, Bioflex Ultra 3/8” Maximum Working Pressure (MWP) Variation with Temperature: MWP for SS grade hose, also for RC, BK and SI grades are as given in the graph, BUT only within the temperature range for the particular grade of hose, as given below: PTFE lined hose. MAXIMUM WORKING PRESSURE IN BARS much higher than that of TEMPERATURE IN DEGREES CENTIGRADE Min/Max Operating Temperatures: Bioflex...

The MWP of the hose reduces as the operating temperature increases as specified...

Bioflex Ultra Hose: Special Usage Conditions • Cleaning & Sterilising Systems - CIP, SIP and Autoclave CIP & SIP – PTFE liner tubes are chemically resistant to all CIP, SIP and Autoclave conditions. A primary consideration is whether the cleaning and purging cycle is likely to develop an electrostatic charge on the internal surface of the liner, in which case AS (Anti-Static) grade hose is required. AS grade hose and Electrostatic charge generating systems are fully described in the hose liner section. CIP systems using high electrical resistivity solvents like Toluene will require AS grade hose....

Quality Assurance, Certification and Approvals, and Hose Testing EN ISO 9001:2008 Aflex products are all manufactured in accordance with BS EN ISO 9001: 2008 Quality Management Systems independently assessed and registered by National Quality Assurance Limited (NQA). EN12115 Bioflex Ultra meets the relevant requirements of EN12115, but the correct specification for the electrical and electrostatic requirements is EN ISO 8031 Annex A.
