Foamed Silicone Soft Filler Fitness Equipment

Why Foamed Silicone as Filling

• Ultra-light: high expansion ratio keeps finished pieces light without sacrificing softness.
• Soft, even core: uniform micropores give consistent feel and support, no migration or settlement.
• In-place molding: flows into the mold or cavity and foams to fill gaps and contours.
• Skin-friendly and safe: non-toxic, non-corrosive, chemically inert for close-contact pieces.
• Durable: flexible from -65C to 200C, insulating and flame-retardant.

Key Applications

Filling for silicone robots and mannequins, chest and shoulder pads, insoles, elderly fitness equipment such as joint hammers and swing balls, pregnancy back supports, children's pillows, and general soft-part cushioning.
