IOTA HTV 335 Series – The High-Rebound, Low-Compression-Set Silicone That Redefines Automotive Keypad Reliability
When every press matters – from a driver’s climate control to a start-stop button – your silicone must deliver tactile confidence, dimensional stability, and lasting performance. The IOTA HTV 335 Series does exactly that.
Engineered for high-rebound, low-compression-set applications, this fumed-silicone rubber series (hardness 30–70 Shore A) combines exceptional resilience with outstanding processability. Whether you are molding premium automotive keypads, sport equipment seats, or high-end sealing components, HTV 335 ensures that parts return to their original shape quickly and consistently – even after millions of cycles.
What sets this series apart?
Low compression set – minimal permanent deformation means longer service life and sustained sealing force.
Excellent flow and mold release – reduces scrap, speeds up cycles, and lowers production costs.
Transparent grades – easy to color-match for interior design requirements.
LFGB compliance – safe for food-contact applications when post-cured at 200°C for 4 hours.
Typical physical properties speak for themselves: tensile strength up to 9.0 MPa, tear strength up to 20 kN/m, and elongation tailored from 550% (soft grades) down to 200% (firm grades). Process with 1.0% peroxide (DBPMH), cure at 175°C for 5 minutes, and get consistent, high-quality 2 mm sheets – batch after batch.
Packaged in 20 kg cartons and stable for 12 months in unopened, cool, dry storage (best used within 3 months for optimum processing), the IOTA HTV 335 Series is the reliable choice for engineers who demand performance without compromise.
