Quick Q&A

  • Do you provide medical‑grade polymer documentation? Documentation options depend on the project scope; we can align required QC items.
  • Can you blend with CaP/45S5? Yes—polymer/CaP composite systems can be designed for OEM needs.
  • How to request a sample? Share target use, size range, and region/device class; we’ll propose a suitable spec window.
