Product Summary
Our liquid silicone foam is a high-performance two-part addition curing silicone rubber, foamed via chemical reaction with A and B liquid components. It features 2–7 times high foaming ratio, uniform foam structure, low shrinkage and excellent temperature resistance from -65℃ to 200℃. Eco-friendly and flexible, it suits industrial sealing, cushioning and filling. We also provide mold making silicone, pad printing silicone, electronic potting compound, human body silicone and robot silicone.
Product Overview
Liquid silicone foam, also known as foamed silicone, silicone foam and silicone sponge, is an environment-friendly RTV-2 dual-component silicone material. It forms lightweight, soft foam after chemical foaming and high-temperature vulcanization, with no limitation on product thickness. Featuring simple operation, stable performance and zero pollution, it is widely adopted in industrial manufacturing and daily flexible product production. As a full-range silicone manufacturer, we support one-stop procurement of multiple core silicone materials for global buyers.
Technical Specifications
This industrial foamed silicone adopts platinum addition curing system. It delivers a controllable foaming ratio of 2–7 times, with ultra-low linear shrinkage rate and lasting rebound elasticity. The sustainable working temperature ranges from -65℃ to 200℃. The cured foam is lightweight, non-migratory and non-atrophic, with excellent chemical inertness, insulation and flame retardant properties, fully meeting industrial standard requirements.
Core Product Features & Advantages
Different from ordinary foam materials, our liquid silicone foam owns prominent comprehensive advantages. It achieves uniform foaming with stable structure and no deformation after long-term use. The non-toxic, non-corrosive and radiation-free formula ensures safe application for household and body-contact products. It integrates heat resistance, cold resistance, electrical insulation and flame retardancy, adapting to complex working environments. Stable batch quality effectively reduces defective rates and lowers clients’ comprehensive production costs.
Application Scenarios & Commercial Value
It is widely used to produce industrial sealing accessories including gaskets, sealing strips, foam boards and printing sponge rollers. It also manufactures silicone insoles, sofa cushions, automotive interior parts, children pillows and fitness equipment components. Additionally, it serves as premium filling material for robot silicone crafts. The easy-processing formula improves production efficiency and reduces raw material waste for downstream manufacturers.
Step-by-Step Usage Instructions
1. Fully stir component A and component B separately to eliminate material stratification caused by long-term storage. 2. Mix A and B components at a standard 1:1 ratio and stir evenly for 2–3 minutes. 3. Conduct vacuum defoaming for the mixed glue and use it quickly to avoid premature coagulation.
Certifications and Compliance
All products comply with ISO9001, CE and RoHS international environmental and quality standards. Each batch undergoes strict pre-production sample testing and pre-shipment final inspection, maintaining consistent quality standards with our mainstream silicone products.
Customization Options
Customized foaming ratio, hardness and formula solutions are available to meet personalized industrial application demands for different industries and production processes.
Production Process & Quality Control
We adopt standardized raw material screening, precise batching, constant-temperature curing and multi-stage quality inspection. Professional QC teams monitor the whole production process to ensure stable performance and consistent batch quality of liquid silicone foam.
Packaging & Storage
Standard packaging: A component 25KG/200KG/250KG drums; B component 25KG/200KG drums. Transported as non-dangerous goods. Store in sealed, cool and dry environment. Avoid sunlight exposure, high-temperature baking and contact with sulfur, phosphorus, tin and heavy metal substances.
FAQ
Q1: What factors will cause curing failure of liquid silicone foam?
A1: Addition curing foam silicone is sensitive to impurities. Contact with water, sulfur, phosphorus, tin and heavy metal substances will inhibit curing. High-temperature baking and long-term sun exposure will damage structural stability.
Q2: What makes your foamed silicone better than peers?
A2: It features controllable high foaming ratio, uniform pores, zero shrinkage and migration, wider temperature adaptability and full international certifications, with reliable batch stability.
