EPDM Number 7 and TFM baked EPDM diaphragms have been designed specifically to improve performance in applications requiring frequent steam cycles.
Innovative formulations in EPDM and PTFE technology mean that the Diaphragm Direct FDA diaphragms can stay in service significantly longer than conventional diaphragms.
EPDM Number 7 compound complies with 21CFR 177.2600 and conforms to 21 CFR 177.1550, and conforms to USP Class VI.
An independent accredited laboratory undertook all diaphragm testing.
A complete validation package is available for trouble-free validation and a quality guarantee.
All finished diaphragms are sealed in individual packages to prevent damage from handling and transit.
Quality: Diaphragm Direct compounds and moulded TFM diaphragm with Number 7 EPDM backing complies to 21 CFR 177.1550 (a), and test requirements as outlined in USP XXIV Class VI Biological Reactivity Tests section 87 and 88.
Diaphragm Direct compounds and moulded peroxide cured Number 7 EPDM complies to 21 CFR 177.2600, and test requirements as outlined in USP XXIV Class VI Biological Reactivity Tests section 87 and 88.
Testing was undertaken by the independent accredited laboratory, NAMSA.
The diaphragm is fully traceable to European specification: EN10204.31B.
A physical properties certificate is available upon request.
Further information regarding the qualitative identification will be available upon written request under supplier/customer confidentiality agreement.
TFM 1600 PTFE Diaphragms PTFE is one of the purest fluoropolymers available today with virtually zero extractables or leachables.
TFM 1600 PTFE is a modified polytetrafluoroethylene (PTFE) that maintains the exceptional chemical and heat resistance properties of conventional PTFE, but has a significantly lower viscosity giving better fusion during sintering resultant smoother surfaces.
This gives benefits of improved resistance to creep and lower deformation under load - reduced cold flow, reduced permeability, denser polymer structure with fewer voids and trapped air, which reduces the risk of trapped contaminants.
The smooth, pore free surface allows for easier cleaning during CIP cycles.
Lower melt viscosity and better fusion during sintering.
Higher tensile strength.
Increased working life of the diaphragm in process involving frequent steam sterilisation (SIP).
This innovative formulation results in diaphragms that can stay in service up to four times longer than conventional diaphragms.
Ultimately, less time will be spent routinely replacing diaphragm, and, there will be fewer interruptions in process run time and reduced cost of the replacement of the diaphragm.
