Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is a high-density high-strength core product, specially developed for high-strength components, load-bearing parts and high-density scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with high-density fillers and strength modifiers, featuring ultra-high density, dense structure, high mechanical strength, fine uniform closed-cell structure, good elasticity and density stability. It has a density of ≥1.2 g/cm³, high tensile strength, high compressive strength, no deformation, effectively bearing load, solving the problem of traditional foaming materials’ low density and poor strength in high-strength scenarios. Compatible with most of our high-strength and load-bearing products, it is ideal for high-density components, load-bearing buffers and high-density scenarios.
