New-Generation Liquid Silicone Foam Optimized

HONG YE SILICONE, a seasoned manufacturer of RTV2 addition curing silicone rubber, launches upgraded liquid silicone foam (foamed silicone / silicone sponge) to fulfill global manufacturers’ demand for lightweight flexible cushioning and sealing materials.

This two-part platinum-cured liquid silicone foam supports adjustable foaming expansion ranging from 2 times up to 7 times. It forms uniform micropores with ultra-low shrinkage and durable rebound performance. The eco-friendly material retains soft elasticity under -65℃ to 200℃, featuring excellent heat resistance, cold resistance, electrical insulation and flame retardancy. The finished foam will not migrate or atrophy after long repeated compression.

The material features simple operation and no thickness restriction for molded products. It can produce industrial sealing parts, printing sponge rollers, automotive interior cushions, household soft pads, healthcare silicone goods, and serve as filling material for robot silicone and human body silicone simulation models.

Our factory provides a complete silicone product portfolio, including mold making silicone, pad printing silicone and electronic potting compound, supplying all-in-one raw material solutions for worldwide B2B buyers. All batches go through strict quality control. Customization of foam density and softness is supported.

Adopting this liquid foaming silicone helps factories lower material scrap and stabilize finished product quality. Our technical team provides professional on-site and remote operation guidance, helping clients avoid curing failure caused by inhibitors like sulfur, heavy metals and water. The product meets global environmental regulations and supports convenient cross-border logistics.
