Product Description

Product Summary

HONG YE SILICONE liquid silicone foam is a premium two-component platinum addition curing RTV2 Silicone Sponge. Featuring 2–7 times adjustable foaming ratio, uniform pores and ultra-low shrinkage, it maintains stable elasticity at -65℃ to 200℃. Eco-friendly and easy to process, it perfectly matches our Mold Making Silicone, Pad Printing Silicone, Electronic Potting Compound, robot silicone and Human Body Silicone for industrial solutions.

Product Overview

Liquid Silicone Foam , also known as Foamed Silicone and silicone sponge, is a professional dual-component heat-vulcanized Addition Curing Silicone rubber. Composed of flowable A and B liquid components, it forms lightweight, soft and elastic foam through chemical foaming reaction. The material has no finished product thickness limitation, with simple operation and stable structural performance. It never migrates or atrophies after long-term use, serving as an ideal eco-friendly flexible material for global mass industrial production.

Technical Specifications

This industrial RTV2 foamed silicone adopts a standard 1:1 mixing ratio for A/B components. It supports 2–7 times stable volume expansion with ultra-low linear shrinkage and excellent rebound resilience. The cured foam retains lasting soft elasticity in extreme temperatures from -65℃ to 200℃. It features non-toxic, non-corrosive and radiation-free properties, with superior chemical inertness, electrical insulation and flame retardancy, fully compliant with global industrial safety standards.

Product Features & Competitive Advantages

Different from ordinary foam materials, our liquid silicone foam boasts highly uniform foaming structure and outstanding stability. It is lightweight with premium soft hand feel, free from deformation and shrinkage after repeated compression. Adopting eco-friendly platinum-cured formula, it supports safe civilian and industrial contact. Strict batch quality control ensures consistent stable quality, effectively reducing manufacturer defective rates and long-term production costs.

Step-by-Step Operation Guide

1. Separately stir component A and B thoroughly to eliminate material stratification caused by long-term sealed storage.

2. Mix the two components at a 1:1 ratio and stir evenly for 2–3 minutes to ensure full homogeneous blending.

3. Conduct vacuum defoaming and use the mixed silicone immediately to avoid premature coagulation and guarantee perfect foaming effect.

Application Scenarios & Buyer Value

Widely used in multiple industries, it manufactures industrial sealing gaskets, strips, foam boards and printing sponge rollers. It also produces automotive interior accessories, household cushions, silicone insoles, children pillows and fitness equipment parts. Additionally, it acts as high-quality filling material for robot silicone crafts. Simple processing greatly improves production efficiency and cuts raw material waste for global factories.

Certifications and Compliance

The product complies with ISO9001, CE and RoHS international quality and environmental standards. Every production batch undergoes strict pre-production testing and pre-shipment inspection, ensuring reliable and stable performance for global industrial and commercial applications.

Customization Options

We support personalized customization of foaming ratio, density, hardness and formula parameters. Custom solutions are available to meet unique production demands for automotive, electronics, daily consumer goods and intelligent equipment industries.

Packaging & Storage Instructions

Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Transported as non-dangerous goods. Store in sealed, cool and dry environments. Avoid sunlight exposure, high-temperature baking and contact with water, sulfur, phosphorus and heavy metal impurities.

FAQ

Q1: What causes curing failure of liquid silicone foam?

A1: Platinum-cured addition silicone is sensitive to impurities. Contact with water, sulfur, tin and heavy metals will inhibit curing. Long-term sun exposure and high-temperature baking will also damage foam structural stability.

Q2: Why choose HONG YE SILICONE foamed silicone?

A2: We provide stable adjustable foaming performance, uniform pores and zero shrinkage deformation. With complete certifications and stable batch quality, it can be matched with mold making silicone and electronic Potting Compound for one-stop procurement, saving production costs for buyers.
