Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a lightweight & high-strength high-density-ratio core product, specially developed for aerospace, lightweight equipment and high-strength lightweight scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with lightweight fillers and high-strength modifiers, featuring ultra-lightweight, high strength, fine uniform closed-cell structure, good elasticity and strength stability. It has a density of 0.2-0.3 g/cm³ (lightweight) and tensile strength of ≥1.5 MPa (high strength), achieving an excellent strength-to-weight ratio, effectively reducing equipment weight while ensuring structural strength, solving the problem of traditional foaming materials’ low strength in lightweight scenarios. Compatible with most of our aerospace and lightweight products, it is ideal for lightweight high-strength components, lightweight buffers and high-strength lightweight scenarios.
