The whole process of medical silicone raw material production is revealed: the key to quality control from raw materials to finished products
- Three major production barriers of medical silicone raw materials
Raw material purity: use medical grade silicon dioxide (purity ≥ 99.9%), heavy metal content is less than 0.001ppm;
Sterile workshop: 10,000-level clean workshop, full dust control in vulcanization and slitting;
Process accuracy: twin-screw extruder temperature control accuracy ±1℃, ensuring molecular structure uniformity.
- 16 quality inspection processes escort safety
Biocompatibility test: 100% pass rate for cytotoxicity and sensitization tests;
Chemical performance test: extraction experiment (simulated body fluid immersion) has no precipitate;
Physical performance test: tensile strength ≥ 8MPa, tear strength ≥ 25kN/m.
