Product Description:
HONG YE SILICONE
liquid silicone Foam is a two-component addition-curing
Foamed Silicone rubber. Before curing, it consists of Part A and Part B. When mixed at 1:1 weight ratio, it undergoes chemical foaming to form a soft, lightweight, elastic material with uniform fine pore structure. It features high foaming ratio, low shrinkage, excellent resilience, and stable performance from -65℃ to 200℃. Compliant with FDA and RoHS, it is widely used for sealing gaskets, insulation tubes, shock-absorbing pads, cushion filling, and flexible silicone products.
Product Overview:
Our Addition-Curing Liquid
Silicone Foam is a professional-grade foaming silicone developed for applications requiring lightweight, flexible, and thermally insulating materials. As a leading manufacturer of
Liquid silicone rubber with over 25 years of experience, we optimize the formulation for uniform pore distribution, stable foaming ratio, and excellent rebound elasticity. Unlike conventional PU foam materials, this platinum-cured silicone foam maintains softness and elasticity across extreme temperatures, resists oxidation aging, and produces no toxic or corrosive byproducts. It is an ideal replacement for PU foam in applications demanding higher temperature resistance, better chemical stability, and food-grade safety. Products made from it mainly serve shock absorption, thermal insulation, sound damping, and cushion filling purposes.
Core Product Features & Advantages:
High foaming ratio: Foaming volume expands 2 to 7 times, providing lightweight filling with excellent coverage for complex-shaped cavities and sealing gaps.
Uniform fine pore structure: Dense and consistent pore distribution ensures stable shock absorption, low deformation rate, and no migration or shrinkage over long-term use.
Extreme temperature stability: Maintains soft elasticity continuously from -65℃ to 200℃, suitable for both cryogenic and high-temperature industrial environments.
Eco-friendly and safe: Non-toxic, odorless, no corrosive emissions, compliant with FDA food-grade and RoHS standards, safe for direct and indirect human contact applications.
Excellent electrical insulation: High dielectric strength and volume resistivity make it suitable for electronic component potting and filling, providing both mechanical cushioning and electrical protection.
Easy operation: Two-component 1:1 mixing ratio, room temperature or heated curing, simple pouring process, no complicated equipment required.
Step-by-Step Usage Instructions:
Raw material stirring: Stir Part A and Part B separately in their respective containers to ensure uniform consistency and activate foaming performance.
Proportional mixing: Mix Part A and Part B at 1:1 weight ratio, stir evenly for 2-3 minutes to form consistent foaming structure with uniform pores.
Vacuum degassing (optional): Place mixed material in vacuum chamber at 0.08MPa for 3-5 minutes to eliminate air bubbles for denser foam quality.
Pouring and curing: Pour into mold or target cavity. Room temperature curing takes 24 hours for full cure; heated curing at 80-100℃ takes 10-15 minutes for initial set. Closed mold foaming yields better results.
Application Scenarios:
Silicone foam sealing rings, gaskets and strips; silicone foam insulation tubes and sheets; shoe insoles, sofa cushions and mattress filling; automotive headrests, gear shift covers and seat cushions; shoulder pads, breast pads and body-safe cushioning; fitness equipment such as joint hammers and swing balls; printer and copier roller sponge tubes; electronic component potting and filling; precious goods packaging cushioning; pregnant woman back support and children's pillows. The addition-curing Foamed Silicone builds reliable shock absorption, thermal insulation and sealing solutions for diverse industrial and consumer applications.
Precautions:
Avoid contact with nitrogen, sulfur, phosphorus, tin, lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, and water. Do not mix with condensation-type silicone or use containers that have previously held condensation-type silicone, as this will cause catalyst poisoning resulting in incomplete curing or non-foaming. As a food-grade and medical-grade silicone, contact with heavy metals may cause tackiness, incomplete foaming, or curing failure.
Packaging & Storage:
Part A: 5KG/20KG/25KG/200KG per drum. Part B: 5KG/20KG/25KG/200KG per drum. Transport as non-hazardous goods. Store in sealed containers in a cool, dry and well-ventilated place. Shelf life: 6-12 months below 25℃. Avoid direct sunlight exposure and high-temperature baking.
