Engineered for Tough Applications – IOTA-HTV 313 Series High Tear Silicone
When your production demands durability, precision, and consistency, the IOTA-HTV 313 Series delivers. Designed specifically for high-strength molded parts such as protective covers, watch straps, wallets, erasers, ornaments, and more, this silicone rubber series combines exceptional tear resistance with outstanding processing ease.
The 313 Series offers six hardness grades—from 25 to 70 Shore A—giving manufacturers the flexibility to match material performance to exact end-use requirements. Whether you need a soft, flexible grip or a firmer structural component, there is a grade tailored for you. Each variant maintains a semi-transparent appearance and exhibits excellent mold release properties, reducing cycle downtime and improving production efficiency.
Performance data, tested under standardized conditions (1.0% peroxide, 175°C for 5 minutes at 15 MPa), confirms the series’ reliability. Tear strength values range from 14 to 30 kN/m, with tensile strengths holding steady at 7–8 MPa across the hardness spectrum. Notably, elongation at break reaches up to 850% for softer grades, ensuring outstanding flexibility in dynamic applications.
Beyond mechanical performance, the IOTA-HTV 313 Series is manufactured to meet rigorous international standards. It has successfully passed ROHS, REACH, and FDA compliance testing, making it suitable for applications with indirect food contact and consumer safety requirements. This certification saves you time in regulatory approval and expands your market reach.
Processing is straightforward with standard peroxide curing systems. The material shows good batch-to-batch consistency, and its plasticity index (ranging from 140 to 280) enables smooth feeding and uniform filling of complex mold cavities. With a shelf life of 18 months when stored unopened below 50°C, the product offers excellent inventory stability.
For manufacturers seeking a reliable, high-strength silicone that balances tear resistance, elasticity, and processability, the IOTA-HTV 313 Series is a proven solution. Contact our technical team to discuss grade selection and customized support for your production line.
