Solution essentials
- Release tuning: release rate is set by the silicone matrix and device geometry; pick the polymer for the target profile.
- Cure compatibility: some APIs/excipients inhibit platinum cure — validate cure with your formulation, or select a compatible grade/cure system.
- Compliance: long-term implantable → unrestricted; choose by contact type and duration; ISO 10993 / documentation per device.
- Combination products: align material documentation with your drug-device regulatory pathway (master-file references where available).
What BIO provides
BIO provides selection, cure-compatibility advice, documentation and supply of NuSil / Avantor silicone for China drug-device combination teams.
FAQ
Why is silicone used for drug delivery?
Its permeability and tunable matrix allow controlled, sustained release; release rate is set by the silicone and device geometry, making it well suited to long-term implants and combination products.
Will my drug interfere with silicone cure?
It can — some APIs and excipients inhibit platinum (addition) cure. Validate cure with your actual formulation; if needed, select a compatible grade or cure system.
Restricted or unrestricted grade?
By contact type and duration — long-term implantable devices need unrestricted implant-grade silicone with ISO 10993 device-level evaluation.
