Large Drug Delivery OEM

Before PolySource

OEM searching for a material for precision disposable cartridges that provides purity, drug compatibility, biocompatibility, and dimensional stability. The material must deliver consistent, reproducible performance and facilitates miniaturization of drug delivery systems.

However…

  • Traditional engineering plastics, or even glass, do not offer a non-ionic, minimally reactive surface.
  • Traditional engineering plastics polar substrate promotes adsorption, denaturation, aggregation, or precipitation.

Application Requirements

  • Complies with global medical and pharma regulations, USP Class VI, ISO 10993, BPA free and FDA complient.
  • A non-ionic, minimally reactive surface
  • A non-polar substrate that does not promote adsorption, denaturation, aggregation, or precipitation
  • glass-clear optics
  • Highly challenging tolerance levels
  • Multi-cavity tooling with fully interchangeable inserts among all cavities

PolySource Solution

Features

  • TOPAS COC provides purity, drug compatibility, biocompatibility, and dimensional stability.
  • TOPAS COC delivers consistent, reproducible performance and facilitates miniaturization of drug delivery systems
  • Unlike other engineering thermoplastics or glass, TOPAS COC offers a non-ionic, minimally reactive surface.

Advantages of New Material

  • The material delivers consistent, reproducible performance and facilitates miniaturization of drug delivery systems.
  • Repeatable performance

Bottom Line

  • By starting at the beginning and understanding “ALL” the complex processing needs, property needs and CTQs, including a non-ionic, minimally reactive surface, PolySource determined TOPAS COC to be the best candidate ensuring the customer consistent and reproducible performance.
