From Raw Gum to Flawless Parts – Engineered Consistency in Every Pellet
What defines a premium high-transparency silicone? Not just initial clarity, but how that clarity holds up after molding, aging, and repeated sterilization. The IOTA HTV320 Series is formulated to deliver enduring optical performance alongside mechanical robustness—making it the preferred choice for manufacturers of premium infant care products, medical disposables, and transparent industrial components.
This range covers five hardness points (30A to 70A), with plasticity systematically calibrated to ensure smooth mixing, easy pigment incorporation, and uniform dispersion. Even at higher durometers (e.g., HTV32070), elongation remains an impressive 400%, while the 50A and 60A grades offer a sweet spot of 10 MPa tensile and 25–30 kN/m tear strength—ideal for thin-walled, high-flex parts that must survive repeated stretching without whitening or stress-cracking.
The numbers speak for themselves: density ranges from 1.08 to 1.20 g/cm³, and light transmittance increases progressively from 85% to 88% as hardness rises—a unique trend that ensures visual appeal across the entire product line. All data are generated using a standardized 2 mm plaque cured with 1.0% peroxide at 175°C for 5 minutes under 15 MPa pressure, providing a reproducible benchmark for quality control.
Beyond physical properties, the HTV320 Series has been independently verified against three major global safety frameworks: RoHS (restriction of hazardous substances), REACH (chemical registration), and LFGB (German food-contact safety). This triple certification streamlines your market access, reducing redundant testing and accelerating time-to-launch for sensitive-use products.
Storage is straightforward—unopened cartons maintain shelf life up to 18 months at ≤50°C—and each 20 kg box is clearly labeled with lot numbers for full traceability. While the data table serves as a reliable reference, we always recommend running pilot trials under your actual processing conditions to fine-tune parameters.
