Product Overview
The low-temperature‑resistant silicone anti‑collision sealing strip is an elastic sealant extruded from a specialized cold‑resistant silicone rubber. Unlike ordinary rubber or standard silicone, its formulation incorporates cold‑resistance modifiers, ensuring continued softness and high elasticity even in extremely frigid conditions, while resisting hardening and brittleness. Integrating multiple functions—impact absorption, dust and air sealing, sound and wind insulation, and waterproofing and thermal insulation—it is available in solid, foamed, U‑shaped clip‑type, D‑shaped, rectangular, and reinforced‑steel‑core profiles, among others. It is widely used in northern outdoor equipment, cold‑chain systems, cold storage facilities, low‑temperature vehicles, and outdoor door and window mechanisms operating under low‑temperature conditions, and can be customized in various colors, food‑grade grades, with adhesive backing, or with metal reinforcement.
Material Classification
General-purpose cold-resistant industrial silicone rubber
Operating temperature: -50°C to 200°C, suitable for both ambient and low-temperature applications, offering excellent cost-effectiveness.
Applications: outdoor cabinets, construction machinery, standard cold storage facilities, and impact‑resistant sealing for doors and windows.
Ultra-low-temperature, special cold-resistant silicone rubber
Operating temperature range: -70°C to 180°C; specially designed for extreme cold regions, sub-zero cold storage facilities, and outdoor specialized equipment.
Features: Remains flexible and does not become brittle or turn white even after prolonged exposure at temperatures below minus several tens of degrees; exhibits no cracking when bent.
Food-grade low-temperature-resistant silicone rubber
Odorless and free of leachables, it is suitable for cold-chain food equipment, low-temperature refrigeration ovens, and commercial cold-storage doors, and supports low-temperature disinfection.
Foamed cold-resistant silicone strip
Lightweight and soft, it offers superior cushioning and sound insulation, with excellent thermal performance—making it the top choice for cold storage facilities and refrigerated truck compartments.
Cold-resistant sealing strip with steel band
Built-in stainless steel/zinc‑plated steel frame, snap‑in installation; at low temperatures, the metal does not rust and the sealing strip remains securely in place.
Product Advantages
Exceptionally resistant to low temperatures; remains tough and non‑brittle even in the cold.
Conventional EPDM, PVC, and standard silicone all become brittle and lose their elasticity at –20°C; this cold‑resistant silicone, however, maintains stable performance down to –50°C or even –70°C for long‑term use, resists cracking under repeated flexing, and retains its resilience without degradation—making it ideal for northern winters and outdoor, exposed equipment.
Universal across a wide temperature range, suitable for both high and low temperatures.
It offers freeze resistance at low temperatures and can withstand short-term exposure to 200°C at high temperatures. Suitable for both winter and summer use, it resists accelerated aging even under alternating hot–cold conditions.
High elasticity with strong cushioning, impact protection, and noise reduction.
Silicone gel is soft and resilient, cushioning impacts when doors are closed or lids are latched, reducing metal‑on‑metal noise, protecting equipment door frames and cabinet corners, and minimizing damage from bumps and scrapes.
Sealed, waterproof, and dustproof; locks in heat for energy savings.
The dense/foamed structure seals gaps, blocking cold air, moisture, and dust; when used in cold storage facilities and refrigerated trucks, it helps minimize cold‑air leakage and reduce energy consumption.
Weather-resistant and anti-aging, ensuring long-term durability outdoors.
Resistant to ultraviolet radiation, ozone, rain, snow, and frost; when exposed outdoors year-round, it does not chalk, crack, or shrink and deform, with a service life far exceeding that of ordinary rubber strips.
Waterproof and resistant to mild acids and alkalis;不易 mold.
In cold storage environments characterized by high humidity and abundant moisture, it remains non‑absorbent and mold‑free, and maintains stable performance under mildly acidic or mildly alkaline conditions.
Eco-friendly and odorless
Free of phthalates and heavy metals; food-grade formulation safe for contact with cold-chain foods, with no volatile emissions.
Multiple installation options to suit a variety of scenarios.
Available options include self-adhesive models, U‑shaped sheet‑metal clips, self‑adhesive D‑shaped strips, and versions with steel‑band fasteners; installation is straightforward, and the product can be cut to size as needed.
