Product Overview
Our liquid silicone Foam is a premium two-component addition curing liquid foaming silicone developed for making Silicone Sponge parts, sealing elements and soft filling layers. As a leading manufacturer of Mold Making Silicone and Silicone raw materials, we optimize the formula for core demands of Foamed Silicone production: stable foaming ratio, fine cell structure, no oil migration and long-term resilience. Unlike ordinary Silicone Foam sheets, our liquid pouring type silicone foam supports unlimited product thickness, avoids shrinkage and atrophy after long-term use, maintains stable soft elasticity, helping procurement partners simplify production process and reduce material waste.
Key Features & Advantages
Controllable Foaming Ratio & Simple Operation: Adjustable foaming expansion from 2 times up to 7 times volume; good fluidity ensures easy pouring, fully fills complex cavities, suitable for one-step pouring foaming molding; simple operation, no complicated physical foaming equipment required, reducing equipment investment and improving production efficiency for procurement partners.
Lightweight Soft Texture & Excellent Rebound: Cured foam is ultra-light with skin-friendly soft touch, outstanding compression recovery; after repeated compression, it can quickly return to original shape, suitable for shock absorption and cushioning products.
Stable Physical Property & Ultra-Low Shrinkage: Low linear shrinkage rate, uniform and fine foam cells; no oil bleeding, no migration or atrophy under long-term service, greatly extending service life of finished foam products.
Wide Temperature & Insulation Performance: Finished foam keeps stable elasticity within -65℃ to 200℃, with good heat resistance, cold resistance, electrical insulation and flame retardant property; chemically inert, non-toxic and eco-friendly for skin-contact products.
Customizable Formula & Flexible Curing: Supports heat accelerated curing, with customizable foaming multiple, hardness, viscosity, operation time and curing time; only Addition Curing Silicone system available to meet different cushion, seal and filling application requirements.
How to Use (Step-by-Step Guide)
Ratio Confirmation: Confirm mixing ratio of Component A and Component B: 1:1 by weight for addition curing liquid silicone foam (confirm technical sheet from manufacturer).
Mixing: Mix Component A and Component B according to specified weight ratio, stir slowly and evenly to reduce air bubbles, ensure full mixing of two components to guarantee uniform foaming effect.
Molding: Pour mixed liquid silicone foam into mold cavity; chemical foaming reaction will happen automatically after mixing. For thick products, single pouring molding is available without thickness restriction.
Curing & Demolding: Cure under heating condition to speed up foaming and crosslinking; after full vulcanization, take out foam parts gently. For stable performance, aging treatment for 24 hours is recommended before formal application.
Application Scenarios
This specialized foamed silicone and industrial liquid silicone foam is mainly used for manufacturing soft cushioning, sealing and filling silicone sponge products. It is widely applied in industrial sealing (silicone gaskets, sealing strips, foam boards, printing sponge rollers), automotive interior accessories (car headrest, gear shift sleeve, seat cushion), daily consumer soft goods (silicone insoles, sofa cushions, mattress fillers, chest pads, children pillows), art craft and robot model filling. It helps procurement partners produce lightweight, high elastic silicone foam parts with consistent quality, lower reject rate and stronger market competitiveness.

FAQ
Q: What contaminants must be avoided during operation?
A: Keep away from sulfur, tin, phosphorus, heavy metal substances and water; these impurities will poison platinum catalyst and cause foaming & curing failure. Avoid long-time direct sunlight storage.
Q: Can I adjust the foaming expansion ratio?
A: Yes, we customize the formula to achieve target foaming multiple according to your finished product density and softness requirements.
Q: Can mixed A+B silicone be stored for later use?
A: No, the mixture will foam and cure automatically. Please use it immediately once mixed.
Q: What are the storage requirements?
A: Keep sealed and stored in cool dry place, shelf life is 12 months.
Q: Is this silicone foam safe for skin-contact products?
A: Yes, non-toxic and eco-friendly after curing, suitable for making chest pads, children pillows and other skin-touch soft products.
