Custom Liquid Foamed Silicone Rolls for Global Sealing

Product Summary

liquid silicone Foam is a high‑performance two‑component addition‑curing RTV silicone rubber for industrial chemical foaming, sealing, cushioning and filling applications. Mixed at 1:1 ratio of A/B flowable components, it achieves controllable 2‑7 times foaming expansion, uniform cell structure, low linear shrinkage and lasting elasticity within‑65℃ to 200℃ working range. Non‑toxic, eco‑friendly and user‑friendly for mass processing. It pairs perfectly with our mold‑making silicone, pad‑printing silicone, electronic‑Potting Compound, human‑body silicone and robot silicone.

Product Overview

Also known as foamed‑silicone and silicone‑sponge, Liquid Silicone Foam belongs to platinum‑cured heat‑vulcanized silicone rubber. Two free‑flowing A and B liquid components generate lightweight soft foam via chemical foaming reaction after mixing and heating curing. There is no restriction on finished‑part wall thickness. Featuring light weight, soft touch and stable physical indexes, this eco‑friendly raw material simplifies production workflows and supports continuous large‑batch manufacturing for worldwide B2B industrial manufacturers.

Technical Specifications

This industrial‑grade addition‑curing‑silicone adopts standard 1:1 mixing ratio for Part A and Part B. It realizes adjustable foaming expansion from 200% up to 700% original volume, with ultra‑low linear shrinkage rate and excellent rebound resilience. Cured foam keeps stable soft elasticity under long‑term‑65℃‑200℃ service environment. It delivers outstanding electrical insulation, flame retardancy, heat & cold resistance as well as superior chemical inertness; the material is non‑toxic, non‑corrosive and non‑radioactive without harmful substance precipitation.

Product Features & Competitive Advantages

Different from ordinary polymer sponge materials, our liquid silicone foam creates evenly distributed foam cells, free of migration, atrophy or post‑curing deformation. Adopting premium platinum addition‑curing formula, it performs stable even for products requiring indirect human contact. Supported by complete in‑house batch‑to‑batch QC management, its consistent quality level is equivalent to our mainstream Mold Making Silicone and Pad Printing Silicone series. It effectively cuts reject rate and overall manufacturing expenditure for global industrial buyers.

Application Scenarios & Buyer Value

This multi‑purpose Foamed Silicone is widely applied for manufacturing industrial sealing rings, gaskets, sealing strips, foam boards, silicone foam tubes and printing sponge rollers. It also produces automotive interior accessories, sofa cushions, silicone insoles, kids pillows and fitness equipment components. Moreover, it acts as ideal filling medium for robot silicone crafts. Straightforward processing steps shorten molding cycle, reduce raw‑material loss and raise overall production efficiency for factories of all scales.

Operation Steps

1. Stir component A and component B separately to eliminate material sedimentation and stratification caused by long‑time storage.
2. Mix A and B liquids at 1:1 ratio and stir thoroughly for 2‑3 minutes to obtain fully homogeneous blend.
3. Carry out vacuum defoaming treatment, then deploy mixed silicone immediately to prevent premature coagulation.

Certifications & Compliance

This liquid silicone foam meets ISO9001, CE and RoHS international quality & environmental‑protection standards. Every single batch passes comprehensive performance test and hazardous‑substance inspection to guarantee reliable quality for global export and diverse industrial usage scenarios.

FAQ

Q1: What triggers incomplete curing of addition‑curing liquid silicone foam?

A1: Platinum‑cured silicone foam is highly sensitive to specific impurities. Contact with water, sulfur, tin and heavy‑metal substances will suppress curing reaction. Long‑term sun radiation and over‑heating will also destroy foam structural stability.

Q2: What practical benefits can this foamed silicone bring for industrial manufacturers?

A2: It provides predictable controllable foaming performance, stable finished‑product quality and low defect rate. Simple‑to‑operate formula reduces labor input and cycle cost, bringing tangible efficiency and economic gains for B2B producers.
