SILPURAN® 8630/60

is an addition-cure, two-component high consistency silicone rubber for the manufacture of extruded articles. The vulcanizates show good to very good mechanical properties and a low coefficient of friction. Compared to SILPURAN® 8030/60 the coefficient of friction is reduced by 50 - 70 %.

SILPURAN® 8630/60 is designed for medical applications in compliance with the WACKER SILICONES HEALTH CARE POLICY including implantation for < 30 days.


SILPURAN® 8630/60 is packaged in accordance with class 8 clean room standards (DIN EN ISO 14644).

SILPURAN® 8630/60meets selected test requirements of ISO 10993 and United States Pharmacopoeia (USP) Class VI. The results of the biocompatibility tests are shown in the table 'Biocompatibility test data'.

Postcured parts can be used for food contact applications and are suitable for use under the Recommendation "XV. Silicones" of the BfR and FDA § 177.2600 under observance of any given limitations on extractable and volatile substances.

SILPURAN® 8630/60 may not be cured with peroxides, but only with the catalyst batch SILPURAN® Curing Agent X. SILPURAN® 8630/60 and SILPURAN® Curing Agent X are mixed homogeneously on a roll mill in a ratio of 100 : 2.0. Care must be taken to keep the mill and compound as cool as possible during mixing. The temperature of the rubber should not exceed 35 °C, since otherwise there is a risk of premature curing seriously reducing the pot life.

Crosslinking begins after SILPURAN® Curing Agent X has been added. The rate and degree of crosslinking depend on the storage time and temperature. At 23 °C, the mixture has a pot life of about 24 h. This can be extended by storing the catalyzed mixture at a lower temperature.

Verpackung / Gebinde

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.


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.
