Premium Silicone Rubber Cord (70° Shore) - High-Temperature Resistant Cord for Commercial and Home Projects

Silicone rubber cord with a 70° Shore hardness is a highly versatile material, offering an excellent balance of flexibility and durability. This grade of silicone is particularly well-suited for applications that require higher strength and resistance to wear while maintaining enough flexibility for a range of uses. Whether you’re in industrial manufacturing, automotive, or DIY projects, Silicone Rubber Cord (70° Shore) offers a reliable and cost-effective solution for sealing, gasketing, and insulation needs. In this article, we’ll explore the key features, advantages, and various uses of Silicone Rubber Cord (70° Shore).

What is Silicone Rubber Cord (70° Shore)?

Silicone rubber cord is a continuous length of flexible silicone material, available in various diameters and lengths, that can be used for a wide variety of applications. The "70° Shore" refers to the hardness of the silicone on the Shore A scale, which measures the rigidity of rubber materials. A 70° Shore silicone is firm but still flexible enough to be molded, shaped, and used in various applications where more robust sealing is required.

This grade of silicone rubber offers superior mechanical strength and resistance to extreme temperatures, chemicals, and environmental factors. It’s a popular material for sealing, gasketing, vibration damping, insulation, and more. Available in standard lengths and diameters, it can be easily cut, shaped, or installed for a custom fit.

Key Features of Silicone Rubber Cord (70° Shore)

1. High-Temperature Resistance: One of the most outstanding properties of silicone rubber is its ability to withstand extreme temperatures. Silicone rubber cord with a 70° Shore hardness can endure temperatures from -60°C to +230°C (-76°F to +446°F), making it an excellent choice for use in environments with fluctuating or high temperatures. It is particularly suited for high-heat applications like engines, ovens, and electrical components that experience constant temperature changes.

2. Enhanced Durability and Strength: Compared to softer silicone grades, the 70° Shore version offers enhanced compression set resistance, meaning it won’t lose its shape or deform permanently after prolonged use under pressure. This makes it more durable and resistant to wear and tear, especially in applications that involve constant pressure or stress.

3. Flexibility and Ease of Installation: Despite its increased hardness, 70° Shore silicone rubber cord remains flexible enough to be manipulated into a variety of shapes and sizes. It can be bent or compressed without cracking, offering high elasticity for installation into grooves, seals, and channels. This makes it easy to apply for both professional and DIY projects.

4. Chemical Resistance: Silicone rubber is naturally resistant to many chemicals, oils, and solvents. The 70° Shore silicone cord maintains its integrity even when exposed to aggressive substances, making it perfect for industrial use in environments where chemical resistance is a key requirement.

5. UV and Weather Resistance: Silicone rubber cord excels in outdoor environments because it is resistant to ultraviolet (UV) radiation and ozone exposure. This resistance prevents the cord from degrading, cracking, or hardening when exposed to sunlight and harsh weather conditions, making it ideal for outdoor sealing, gasketing, and insulation tasks.

6. Electrical Insulation Properties: Silicone rubber is an excellent electrical insulator, which makes 70° Shore silicone cord ideal for electrical wiring, cable insulation, and connector seals. It helps protect electrical components from damage due to short circuits or exposure to moisture and other environmental factors.

Benefits of Using Silicone Rubber Cord (70° Shore)

1. Longevity and Reliability: Silicone rubber cord (70° Shore) provides long-lasting performance. Due to its robust resistance to high temperatures, chemicals, and wear, it will continue to perform well even in demanding conditions. This durability leads to less frequent replacements and maintenance, saving both time and money in the long term.

2. Versatility for Various Applications: From gaskets and seals to vibration dampening, insulation, and custom applications, silicone rubber cord is incredibly versatile. It’s suitable for use in a wide range of industries, including automotive, electrical, industrial manufacturing, and DIY applications. It can be easily adapted to suit specific needs, from sealing doors and windows to protecting sensitive electronics.

3. Easy to Handle and Install: Working with silicone rubber cord (70° Shore) is easy and convenient. It can be cut to the desired length with basic tools, and it is easy to install with adhesive or mechanical fastening. Its flexibility and elasticity allow it to fit snugly into grooves, channels, or seams, creating tight seals without special equipment or complicated procedures.

4. Cost-Effective Solution: Despite its excellent performance and reliability, silicone rubber cord is an affordable solution. It provides a long-lasting, high-performance material at a reasonable cost, offering great value for money for both small and large-scale projects.

5. Environmentally Friendly: Silicone rubber is a non-toxic, environmentally friendly material that doesn’t release harmful substances into the environment. It’s a sustainable choice, as it is recyclable and does not cause pollution, making it ideal for companies or individuals looking to reduce their environmental impact.

Common Applications of Silicone Rubber Cord (70° Shore)

1. Sealing and Gaskets: Silicone rubber cord (70° Shore) is primarily used for creating custom seals and gaskets. Whether it’s for sealing pipes, doors, windows, or equipment, silicone rubber cord provides a reliable, tight seal that prevents water, air, dust, and chemicals from entering or escaping.

2. Vibration Dampening: In industries like automotive or machinery, silicone rubber cord is often used for vibration isolation. It helps absorb shocks and vibrations, protecting components from wear and improving the overall performance and lifespan of machinery and vehicles.

3. Electrical Insulation: Due to its excellent insulating properties, silicone rubber cord is frequently used in the electrical industry for cable insulation, wiring, and connector sealing. It ensures electrical systems remain safe, insulated, and protected from short circuits, moisture, and physical damage.

4. Automotive Applications: In the automotive industry, silicone rubber cord is commonly used for sealing under the hood, including sealing areas around engine compartments, radiators, and vents. Its high-temperature resistance makes it ideal for applications that experience frequent exposure to heat.

5. Home and DIY Projects: DIY enthusiasts use silicone rubber cord for a variety of applications around the home. It’s ideal for weatherproofing doors and windows, plumbing seals, or even crafting custom gaskets for appliances and equipment. Its ease of use and ability to cut to size make it a perfect material for home improvement projects.
