Liquid Silicone Foam Answers Growing Demand for Lightweight S
Product Overview
HONG YE SILICONE introduces its Liquid Silicone Foam — a platinum-cured, two-component addition curing silicone rubber engineered for chemical foaming. Mixed as Part A and Part B, the liquid foaming silicone rubber expands into a soft, lightweight, environmentally friendly cellular material whose finished-part thickness is never limited by the process. Supplied under ISO9001-certified quality control as part of the company's broader RTV-2 silicone rubber and liquid silicone range, this foamed silicone serves industrial buyers in more than 138 countries.

Product Features and Advantages
-
Lower Cost per Part — Expansion to up to 7× volume reduces raw material consumption, lowering unit production cost.
-
Batch-to-Batch Consistency — Uniform cells, stable foaming, low linear shrinkage, and dependable rebound ensure repeatable quality.
-
Featherlight Feel — Soft, elastic, and pleasant to the touch, with no migration, compression set, or shrinkage in service.
-
Non-Toxic and Inert — Free of toxicity, corrosion, and radioactivity; chemically stable and suitable for human body silicone and skin-contact applications.
-
Wide Service Window — Maintains flexibility and sealing from -65°C to 200°C, with good heat, cold, electrical insulation, and flame-retardant performance.
-
Production Friendly — Simple 1:1 mixing, ambient or heat cure, and compatibility with manual or automated dispensing equipment.
-
How to Use — Step by Step
-
Stir Component A and Component B thoroughly and separately before use to correct any storage settling.
-
Blend A and B at a 1:1 weight ratio, mixing continuously for 2–3 minutes to a homogeneous consistency.
-
Apply vacuum degassing to the mixture, then dispense promptly to avoid premature gelation.
-
Cast or inject into the mold and allow foaming and complete curing at ambient or elevated temperature.
-
Application Scenarios
This versatile foam serves multiple sectors:
-
Seals & Gaskets: O-rings, sealing pads, foam strips, foam boards, silicone foam tubing, and printer/copier roller sponge sleeves.
-
Comfort Goods: Silicone insoles, sofa and mattress padding, automotive headrests, gear knob covers, and seat cushions.
-
Apparel & Care: Bra padding, shoulder pads, senior fitness equipment (joint massagers, exercise balls), maternity back supports, and infant pillows.
-
Filling & Prototyping: Internal filler for silicone robots, lifecasting mannequins, and prosthetic devices.
-
Electronics: Lightweight filling and damping compatible with electronic potting compound assemblies.
Buyer Value: Reduced material cost through high expansion; improved part consistency through uniform cells; longer product life and fewer warranty claims through a wide temperature range.
Certifications and Compliance
Produced in an ISO9001-certified facility, with UL and CE certification. The addition curing silicone formulations satisfy global environmental and safety requirements, supporting smooth customs clearance and market entry in North America, Europe, the Middle East, and Asia-Pacific.
Customization Options
Custom formulations available: adjustable hardness and foaming ratio, color matching, low-viscosity grades for automated lines, high flame-retardant versions, and food-contact or medical-grade options developed for your application.
Production Process
Raw material incoming QC → precision batching of A and B → vacuum compounding → laboratory testing (viscosity, expansion, hardness) → sealed drum packaging → pre-shipment final inspection. Backed by 48 production lines and 23+ years of silicone manufacturing experience.
