In the field of silicone products for maternal and infant care, medical hygiene, and food contact applications, material transparency and safety are the core indicators of customer concern. The High-Transparency Fumed Silicone Rubber IOTA HTV320 series, launched by IOTA SILICONE OIL ANHUI CO.,LTD. (hereinafter referred to as "IOTA"), has become the ideal material choice for pacifiers, medical consumables, and high-transparency silicone miscellaneous parts, thanks to its high light transmittance, high strength, and multiple international certifications.
IOTA HTV320 is a high-transparency silicone rubber produced by IOTA using the fumed silica method. It has passed ROHS, REACH, and LFGB testing certifications. The main technical parameters are as follows:

|---|---|---|---|---|
| Hardness (Shore A) | 30 | 40 | 50 | 60 |
| Density (g/cm³) | 1.08 | 1.11 | 1.14 | 1.17 |
| Tensile Strength (MPa) | 9 | 10 | 10 | 10 |
| Elongation (%) | 850 | 750 | 650 | 550 |
| Tear Strength (KN/m) | 20 | 22 | 25 | 30 |
| Light Transmittance (%) | 85 | 86 | 87 | 87 |
Curing Condition: 1.0% peroxide (2,4-dichlorobenzoyl peroxide), compression cured at 175℃ for 5 minutes, tested on 2mm thick samples [1].
1. Maternal and Infant Products
Suitable for silicone pacifiers, baby teethers, feeding tools, and other products. The high transparency makes it easy to observe internal cleanliness, and LFGB certification ensures safety for food contact.
2. Medical and Hygiene Products
Can be used for medical catheters, seals, laboratory consumables, and other medical products with strict requirements for material purity, meeting the standards for medical device materials [2].
3. High-Transparency Silicone Miscellaneous Parts
Suitable for silicone products with high requirements for appearance transparency, such as cosmetic containers, lighting accessories, and decorative items, with a light transmittance of up to 87%.
4. Food Contact Products
Passed relevant FDA tests, making it safe and non-toxic for use in kitchenware such as baking molds, ice cube trays, and food sealing lids.
The core competitive advantages of IOTA HTV320 include:
When stored unopened at or below 50℃, the product has a shelf life of 18 months from the date of production.
Packaging: 20KG/carton. If the shelf life is exceeded, performance testing is required to confirm compliance before continued use [3].
With the rising consumer demand for the safety of maternal/infant products and food contact materials, the market demand for high-transparency, high-strength fumed silicone rubber continues to grow. IOTA provides customers with technical support ranging from material selection to process optimization, supporting sample testing and validation.
