Liquid silicone rubber is a high purity platinum-cure silicone.
Medical device manufacturers favour liquid silicone because of its biocompatibility and excellent part quality. Moreover, the reduced human contact during processing reduces the risk of contamination, especially when manufactured in a clean room environment.
It is typically supplied in two parts with one of the parts containing the platinum catalyst. These are then automatically mixed with any colours and ingredients which may be required. The mixing produces a very homogeneous material that leads to products that are not only very consistent throughout the part, but also from part to part.
The platinum-cure silicone used for Medisil products meets or exceeds the following globally recognised quality standards:
- ISO 10993
- US Pharmacopoeia Class VI
- European Pharmacopoeia 3.1.9
- FDA CFR177.2600
- BfR and FDA Food Contact Regulations
