Where Resilience Meets Processability – IOTA-HTV 318 Series for Demanding High-Elasticity Applications Manufacturers of premium silicone goods face a constant challenge: achieving high rebound without sacrificing moldability or mechanical strength. The IOTA-HTV 318 Series solves this with a balanced fumed-silica formulation that delivers industry-leading rebound values (50–60%) across a full hardness spectrum from 30 to 70 Shore A. This makes it the go-to solution for producing durable sports seating, non-slip kitchen mats, vibration-damping gaskets, and long-lasting sealing profiles that require repeated flexing.
Performance data speaks volumes. Using 1.0% bis(2,4-dichlorobenzoyl) peroxide curing at 175°C for 5 minutes, the series achieves tensile strengths up to 9 MPa and tear strengths up to 20 kN/m, ensuring your products withstand punctures and dynamic stress. Elongation at break ranges from 550% (softer grades) to 200% (harder grades), offering design freedom for thin-walled or thick-section parts. The semi-transparent appearance also supports aesthetically sensitive applications where visual quality matters.
Equally important is its processing advantage: consistent plasticity levels (140–260) guarantee reproducible mill mixing, reduced batch-to-batch variation, and clean demolding. The compound flows readily into intricate cavities, reducing reject rates and cycle times. Furthermore, it meets ROHS, REACH, and LFGB requirements, giving you immediate access to global markets including Europe and North America without extra certification hurdles.
Each 20 kg box ensures easy handling, and with an 18-month shelf life under recommended storage conditions, you can plan production confidently. Don’t settle for ordinary silicone—choose the IOTA-HTV 318 Series to elevate your products’ rebound, durability, and market appeal.
