Product Description

Product Summary

HongYe silicone rubber.Precision low shrinkage dimensional stable Silicone Foam is a high-tolerance addition curing Foamed Silicone for precision molding. It features ultra-low linear shrinkage and zero post-curing deformation, ensuring consistent size and flatness for every finished piece. Stable and easy to process, it works with Prototype silicone and robot silicone, ideal for precision customized foam parts and high-tolerance industrial accessories.

Product Overview

Precision dimensional stable liquid silicone foam is an upgraded RTV2 Foaming Silicone Rubber developed for high-precision customized molding. Traditional foamed silicone often suffers from shrinkage, warping and size deviation after curing, while this optimized formula realizes ultra-low shrinkage rate and excellent structural stability. The foaming structure is uniform and dense without local hollowing or uneven stress. Unrestricted by product thickness, it features simple 1:1 operation, safe environmental performance and long-term dimensional stability. It is highly compatible with prototype silicone and Mold Making Silicone, perfectly meeting high-precision size tolerance requirements.

Core Features & Advantages

1. Ultra-low linear shrinkage, no warping, twisting or deformation after curing.

2. High dimensional consistency, zero batch size deviation for mass production.

3. Uniform internal stress, no local collapse or uneven foaming.

4. Long-term stable size, no shrinkage or atrophy in long-term use.

5. Wide temperature resistance, stable size under temperature alternation.

6. Easy precise molding, suitable for complex special-shaped parts.
