Product Description

Product Abstract

Hong Ye silicone rubber's High-Speed Rail Pavement Heat-Insulating Sealing Foaming Silicone Rubber is rail infrastructure weather-resistant Addition Curing Silicone, track bed gap waterproof heat insulation RTV Silicone Foam. Made from road engineering high-temperature resistant liquid silicone, this track bed buffer sealing Foam Silicone features high-low temperature cycle resistance, anti-road expansion crack, waterproof sealing and frost heave resistance, with adjustable 4-7 times high-toughness foaming ratio. It is used for high-speed rail track bed gap filling, railway pavement expansion joint sealing, rail foundation frost-proof buffer layer, viaduct track heat insulation filler. Matched with road engineering standardized Mold Silicone, the weather-resistant Foamed Silicone forms anti-crack durable Silicone Sponge for long-term rail transit infrastructure protection.

Product Overview

This railway infrastructure dedicated two-component liquid silicone is modified with anti-expansion and anti-crack formula, adapting seasonal temperature alternation of railway pavement from -30℃ to 180℃. As engineering durable Addition Curing Silicone, it buffers track bed thermal expansion and contraction stress to avoid pavement cracking and damage. After high-toughness closed-cell foaming, it forms waterproof heat-insulating Silicone Sponge. Different from ordinary road sealing materials easy to age and crack, this weather-resistantRTV Silicone Foam adapts perennial outdoor rail operation, belonging to high-speed rail infrastructure core protective Foaming Silicone Rubber.

Core Product Features & Advantages

1. Temperature cycle anti-crack: Flexible structure of Foaming Silicone Rubber adapts track bed thermal expansion and cold contraction.

2. All-weather weather resistance: Engineering modified liquid silicone resists wind, rain, frost and snow erosion all year round.

3. Track bed waterproof protection: Dense Foam Silicone prevents rainwater infiltration from corroding rail foundation.

4. Frost heave resistance and shock absorption: Elastic Addition Curing Silicone buffers winter road frost heave extrusion force.

5. Road engineering molding: Fits high-speed rail infrastructure standardized Mold Silicone construction.

6. Ultra-long engineering life: Cured Foamed Silicone maintains performance for more than 15 years outdoors.

Step-by-Step Usage Instructions

1. Engineering stirring: Stir rail engineering grade A/B liquid silicone fully to disperse anti-crack modifiers evenly.

2. Stable ratio mixing: 1:1 uniform stirring for 3 minutes to stabilize weather-resistant and anti-crack performance.

3. Structural defoaming: Remove internal bubbles to enhance overall compactness of engineering Silicone Sponge.

4. Engineering mold curing: Mold shaping via railway standard Mold Silicone to obtain sealing RTV Silicone Foam.

Application Scenarios

High-speed rail track bed gap sealing filler, railway pavement expansion joint waterproof strip, viaduct rail heat insulation buffer layer, suburban railway frost-proof shockproof pad, urban light rail foundation protective foam. The durable Foamed Silicone effectively avoids rail pavement cracking and foundation corrosion.

Precautions

Avoid sharp stone long-term cutting damage to prevent structural fracture of Addition Curing Silicone.

Packaging & Storage

200KG road engineering heavy-duty barrel, ventilated dry storage, keep engineering weather resistance of raw Foam Silicone.
