Innovative micro seal kits for precision engineered analytical equipment A micro seal production technique that replaces individual seals with a web of seals linked by an ultra-thin membrane has been developed by high performance seals specialist, Precision Polymer Engineering (PPE). The seals are available in a full range of FDA, USP Class VI and FCN compliant elastomers for use in analytical and bio-analytical equipment.
PPE is using 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", says David Holt, International Business Manager, PPE Ltd. 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. |
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.
