Beat the Heat with Precision – IOTA-HTV 330 Series Thermally Conductive Silicone Rubber
In the world of thermal management, every degree matters. The IOTA-HTV 330 Series is engineered for manufacturers who demand consistent heat dissipation, mechanical strength, and processing reliability—all in one versatile material platform.
This series covers a broad hardness range from 30 to 80 Shore A, giving you the flexibility to match durometer to application, whether you are producing soft thermal tapes or firmer gap pads. What sets the HTV 330 apart is its balanced property profile: tensile strengths reach up to 800 KN/m, tear strengths remain stable between 0.8–0.9 MPa, and elongation at break adapts from 6% to over 11%, depending on grade.
Thermal conductivity spans from 0.5 to 2.0 W/(m·K), with model-specific values clearly defined—from IOTA-HTV 33030 through 33080. This allows engineers to select the exact thermal performance level without overspecifying or compromising on processability. The material is cured using a DBPMH system, which provides excellent heat resistance and is compatible with compression molding processes.
Importantly, the IOTA-HTV 330 series is fully compliant with RoHS and REACH requirements, supporting your global market access and sustainability commitments.
Processing is straightforward: with just 1% of a 50% DBPMH paste curative, typical molding conditions are 175°C for 5 minutes at 15 MPa. The material is supplied in 20 kg cartons and offers a 12-month shelf life when stored unopened in a cool, dry place away from direct sunlight. For best results, we recommend using within three months of receipt; beyond that, a simple extended mixing time restores full workability.
Whether you are scaling up production or developing new thermal interface products, the IOTA-HTV 330 Series delivers predictable performance, batch-to-batch consistency, and the technical support you need.
