Ampacet ProVitalTM+ Gamma-Protect preserves polypropylene-based medical plastics during sterilisation process

Ampacet, a global masterbatch leader, has introduced ProVital+ Gamma-Protect, a medical-grade additive designed to preserve mechanical and optical properties of polypropylene-based medical and pharmaceutical articles during gamma and e-beam sterilisation processes.

Gamma and e-beam sterilisation techniques are commonly used by the medical industry to eliminate microorganisms such as bacteria, viruses and spores from medical devices, in-vitro diagnostic equipment and packaging systems. However, gamma and e-beam sterilisation methods are known to alter the optical and mechanical properties of the polymers, including elongation, tensile and impact strength.

Ampacet ProVital+ Gamma-Protect is an efficient medical grade additive solution that stabilises polypropylene during gamma or e-beam sterilisation processes and helps to preserve mechanical and optical properties and prevent degradation of the polymer. Applications include medical devices, in-vitro diagnostic equipment and pharmaceutical packaging systems.

Ampacet ProVital+ Gamma-Protect has also been successfully pre-evaluated for biocompatibility according to ISO 10993 part 5, 10 and 23 (cytotoxicity, sensitisation and irritation) at a letdown ratio of 5%.

Ampacet ProVital+ Gamma-Protect provides full consistency of formulation with a no-change policy for raw materials at CAS and commercial levels, with manufacturing under consistent process parameters and cleanroom production to minimise cross contamination risks.
