Product Description

Product Abstract

Closed Cell Foamed Silicone is a professional RTV liquid silicone foam with compact closed-cell structure, foaming multiple from 2 to 7 times. Featuring outstanding airtightness, waterproofness and compression resistance, this Silicone Sponge is designed for industrial sealing gaskets. It can cooperate with Liquid Tank Sealant for tank and pipeline sealing, effectively block water, dust and air leakage, and cut the maintenance cost of industrial pipeline systems for buyers.

Product Overview

This closed-cell foamed silicone is Addition Curing Silicone rubber in liquid state. Different from open-cell silicone sponge, it forms fully closed pores after foaming and vulcanization. It has stable chemical inertness and strong compression recovery, becoming the preferred material for high-demand industrial sealing parts and industrial Mold Silicone supporting products.

Core Product Features & Advantages

Airtight closed cell: Dense internal structure, excellent waterproof, dustproof and air isolation effect.

Strong compression recovery: Recover quickly after compression, keep stable sealing performance for a long time.

Chemical resistance: Resist weak acid, alkali and common industrial solvents, no chemical reaction.

Temperature stability: Work stably within -65℃ to 200℃ in harsh industrial environments.

Uniform foaming: Consistent pore size, stable overall size, no local deformation.

Step-by-Step Usage Instructions

Stirring: Fully stir A and B components to eliminate settlement caused by storage.

Mixing: Mix at 1:1 standard ratio and stir thoroughly for 2-3 minutes.

Defoaming & filling: Remove bubbles via vacuum, then fill into sealing molds quickly.

Curing & forming: Heat to complete foaming, obtain finished closed-cell sealing foam.

Application Scenarios

Ideal for pipeline flange gaskets, storage tank edge sealing strips, mechanical equipment dustproof cushions and outdoor cabinet waterproof gaskets. It matches Filter Potting Silicone to enhance the overall sealing performance of industrial filtration and storage equipment.
