Foamed Silicone Cabin Noise Control Sponge

Product Overview

This automotive foamed silicone is engineered for the demanding cabin environment of passenger cars, commercial vehicles and new-energy platforms. The elastic closed-cell structure of liquid silicone Foam cushions seating, damps structure-borne vibration and absorbs airborne noise across the cabin, while the flame-retardant, low-VOC silicone matrix supports interior air quality and fire-safety requirements. Different from PU foam that ages, yellows and releases odors in hot cabins, this Silicone Sponge keeps its support, damping and cleanliness over the full vehicle lifecycle. With adjustable density, hardness and thickness, this RTV Silicone Foam fits seats, panels and NVH layers, making it a dependable Foaming Silicone Rubber for automotive interior engineering.

Core Product Features & Advantages

1. Cabin comfort: High-rebound Silicone Sponge cushions seats and reduces fatigue on long drives.
2. NVH control: Damping Liquid Silicone Foam reduces road, engine and structure-borne noise.
3. Lightweighting support: Low-density Foam Silicone trims vehicle weight and supports energy efficiency.
4. Low-VOC cleanliness: Inert RTV Silicone Foam resists odor and outgassing in hot cabins.
5. Flame safety: Flame-retardant Foaming Silicone Rubber supports interior fire-safety requirements.
6. Long-life durability: Aging-resistant Foamed Silicone keeps performance across temperature cycling.

Step-by-Step Usage Instructions

1. Component stirring: Stir the two parts of Liquid Silicone evenly for consistent automotive-grade foam.
2. Ratio mixing: Blend at 1:1 for about 3 minutes to build a uniform comfort Foaming Silicone structure.
3. Vacuum de-airing: De-gas to refine cell uniformity and NVH performance of the Silicone Sponge.
4. Mold forming: Shape seat and panel layers with Mold Silicone tooling and cure to finished Foamed Silicone parts.

Application

Scenarios Seat cushion and backrest layers, headrest and armrest padding, door and floor NVH pads, roof liner insulation, trunk and parcel shelf trim and EV cabin comfort parts. This high-stability Foamed Silicone provides quieter, lighter and more comfortable cabin solutions for automotive interior and NVH projects.

Precautions

Avoid contact with cure-inhibiting substances such as nitrogen, sulfur, phosphorus, tin, lead, cadmium and mercury; keep away from direct sunlight and high-temperature baking before curing.

Packaging & Storage

25 kg sealed drums, stored dry and cool with lids closed to preserve foaming performance; shipped as non-hazardous cargo.
