Packaging

SILPURAN® HCR is delivered in blocks (profile diameter = approx. 90 x 100 mm) that are wrapped in an antistatic film and heatsealed in a bag. The customer can thus be sure that the material is not contaminated before it enters the cleanroom. SILPURAN® HCR is packaged in accordance with class 8 clean room standards (DIN EN ISO 14644).

SILPURAN® is neither produced nor packed under sterile conditions, so the final product has to be sterilized prior to use, if necessary.

Storage

Please store the cardboard boxes in a dry and cool place. Already opened boxes should be closed again to avoid any contamination.
The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
