High Resilience and Low Compression Set – IOTA HTV 335 Series Silicone Rubber
When application requirements call for durable, high-rebound elastomers with excellent dimensional stability, the IOTA HTV 335 Series stands out as a trusted solution. Developed using fumed silica reinforcement, this silicone rubber series is engineered to deliver consistently low compression set and superior resilience, ensuring long-term performance in dynamic sealing and cushioning applications.
The series covers a comprehensive hardness range of 30 to 70 Shore A, allowing designers and engineers to select the optimal grade for specific functional needs. From automotive keypads to sporting goods seats and industrial sealing components, IOTA HTV 335 provides reliable mechanical performance across a variety of demanding environments.
Processing efficiency is a key advantage of this material. With excellent millability and molding characteristics, it supports stable production cycles and minimizes waste. The product also meets food contact material standards, broadening its suitability for applications where regulatory compliance is required.
Key physical properties include tensile strength up to 9.0 MPa, tear strength up to 20 KN/m, and elongation tailored to each hardness level. These properties are achieved using a 1.0% peroxide curing agent (DBPMH) under standard press cure conditions. For end-use applications, a post-cure of 4 hours at 200°C is recommended to realize the material’s full potential.
Packaged in 20 kg containers, IOTA HTV 335 Series offers a one-year shelf life when stored properly. To maintain optimal processing and performance, it is advisable to use the material within three months after opening. Backed by consistent quality and comprehensive technical support, this series delivers dependable results for manufacturers seeking high-performance silicone materials.
