From Food-Contact Safety to High-Cycle Durability – IOTA HTV 335 Elevates Your Silicone Parts Portfolio
In the competitive world of automotive interiors and precision molded goods, your material must pass more than just mechanical tests – it must pass market expectations. The IOTA HTV 335 Series delivers on all fronts: rebound resilience, compression set resistance, processing ease, and regulatory peace of mind.
This fumed-silicone family (30A to 70A) is built for demanding applications like automotive keypads, where haptic feedback and long-term shape retention are non-negotiable. With a Williams plasticity range from 140 to 260, each grade offers predictable, stable viscosity for injection or compression molding – reducing setup time and improving yield.
Key benefits for manufacturers and brand owners:
Superior rebound – maintains tactile click-feel over extended use.
Low permanent set – ensures gaskets and seals keep their function under constant load.
Fast, flash-free processing – compatible with standard peroxide cure systems.
LFGB-certified formulation – opens doors to food-contact tableware, matting, and kitchen accessories after proper post-cure (200°C / 4 hours).
Performance data across the 33530 to 33570 grades confirms reliable tensile strength (5.5–9.0 MPa), tear resistance (12–20 kN/m), and controlled density (1.08–1.18 g/cm³). Whether you need a soft, high-elongation compound or a firmer, wear-resistant material, there is a grade ready for your cavity.
Storage is straightforward – 20 kg cartons, shelf life of 1 year (unopened), with a recommendation to use within 3 months for best workability. Even beyond that period, simple remilling often restores processability, giving you flexibility in inventory management.
Don’t settle for ordinary silicone when your application demands extraordinary resilience. Explore the IOTA HTV 335 Series – where durability, safety, and process efficiency converge.
