Precision Polymer Engineering announces a new range of Food and Drug Administration (FDA) conforming perfluoroelastomers for use in all food and pharmaceutical applications
The seals are available in a full range of FDA, USP Class VI and FCN compliant elastomers for use in laboratory and bioanalytical equipment.
Demands for micro elastomer seals measuring a few millimetres are growing within analytical and bio research equipment markets where purity, and ability to withstand a wide range of chemicals and temperatures, are the norm.
PPE is offering equipment manufacturers the opportunity to replace individual seals with a single web of multiple seals.
The seal web makes equipment assembly quicker and ensures all seals are installed correctly.
PPE uses finite element analysis techniques and precision tooling to develop the micro seals which are normally bespoke to meet the needs of individual manufacturers.
The seals are also subject to cryogenic deflashing to remove all traces of surplus elastomer and produce a "clean" seal for immediate use.
"Micro seals are fiddly to handle and can sometimes be installed incorrectly where differences in individual seals may be just a few millimetres, by linking the seals together we overcome this potential problem and reduce the time taken to install the seals individually", says David Holt, International Business Manager, PPE.
Precision Polymer Engineering's FDA, USP Class VI and FCN compliant hygienic sealing materials range from grades of EPDM (ethylene propylene rubber), NBR (acrylonitrile butadiene rubber), silicone rubber, fluoroelastomer, through to HNBR (hydrogenated nitrile rubber) and Perlast FFKM perfluoroelastomers.
