Uncompromised Clarity and Strength – Redefining High-Transparency Silicone for Critical Applications
When every millimeter matters—whether in a baby’s feeding teat, a medical tube, or a precision-molded gasket—you cannot afford variability. Introducing IOTA HTV320 Series high-transparency gum silicone: a material engineered not just to meet standards, but to exceed expectations in clarity, mechanical resilience, and processing consistency.
Unlike conventional transparent silicones that sacrifice toughness for aesthetics, the HTV320 family delivers a rare balance: optical transmittance up to 88% (rivaling optical-grade polymers) combined with tensile strengths of 9–10 MPa and tear resistance reaching 30 kN/m. This means finished parts remain crystal-clear after molding, resist tearing under repeated flexing, and maintain their gloss over extended service life—critical for nipple, healthcare, and food-contact articles where visual inspection and durability are non-negotiable.
Processors will appreciate the stable plasticity values (155–280) across five hardness grades—30, 40, 50, 60, and 70 Shore A—allowing precise match to application needs without retooling. The compound responds predictably to standard peroxide curing (1% bis(2,4-dichlorobenzoyl)peroxide, 175°C×5 min×15 MPa), delivering flash-free demolding and low batch-to-batch variation. Whether you run injection, compression, or transfer molding, the HTV320’s excellent flow characteristics reduce cycle wastes and reject rates.
Importantly, this material comes fully validated to RoHS, REACH, and LFGB criteria—essential for global exports to the EU, US, and Asian markets. No questionable additives, no hidden leachables; just reliable, compliant performance backed by full traceability.
Packaged in convenient 20 kg cartons and stable for 18 months when stored below 50°C, the IOTA HTV320 Series is ready for rigorous production schedules. For engineers seeking a transparent silicone that doesn’t force trade-offs between clarity, strength, and processability, this series offers a proven, field-tested solution.
