A Comprehensive Guide to Silicone Rubber Strips in China
Silicone rubber strips are versatile materials widely used in various industries due to their unique properties. China is a major producer and exporter of these strips, with numerous manufacturers offering a wide range of products. This guide delves into the technical aspects, different types, and applications of silicone rubber strips from Chinese manufacturers like Suconvey Rubber (suconvey.com), Nanjing New Run Rubber&Plastic Co.Ltd (www.nrsiliconerubber.com), Sponge Silicone (www.spongesilicone.com), BD SEALS (www.bodiseals.com), and JESilicone Company (www.jesilicone.com).
Understanding Silicone Rubber Strips
Silicone rubber strips are manufactured through extrusion processes, creating long, continuous lengths of various shapes and sizes. Their inherent flexibility and resistance to extreme temperatures, chemicals, and UV radiation make them ideal for sealing, insulation, and cushioning applications. The material’s non-toxicity and food-grade options expand their use to medical and food processing environments. Manufacturers like Suconvey Rubber offer both standard and custom-sized strips to meet diverse needs.
Technical Features of Silicone Rubber Strips
The performance of silicone rubber strips is determined by several key technical parameters. These parameters vary based on the specific application and manufacturing process. Companies such as Sponge Silicone highlight the importance of these features in their product descriptions.
| Feature | Description | Units | Typical Range |
|---|---|---|---|
| Tensile Strength | Resistance to stretching before breaking | MPa | 2-25 |
| Elongation | Percentage of stretching before breaking | % | 300-650 |
| Hardness (Shore A) | Measurement of material’s resistance to indentation | Shore A | 20-90 |
| Temperature Range | Operational temperature range without significant degradation | °C | -60 to +350 (depending on grade and formulation) |
| Tear Strength | Resistance to tearing | N/mm | Varies with grade and thickness |
| Specific Gravity | Density of the material | g/cm³ | 0.9-1.3 |
Types of Silicone Rubber Strips
Several types of silicone rubber strips cater to diverse applications. Nanjing New Run Rubber&Plastic Co.Ltd. offers a variety of silicone rubber sheets, tubes, and strips. These differences are crucial for choosing the right material for a specific application.
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Solid Silicone Rubber | A dense, non-porous strip with high strength and durability. | Excellent sealing, durability, and resistance to chemicals and extreme temperatures. | Less flexible than other types; may not be suitable for applications needing cushioning. |
| Silicone Sponge Rubber | A porous strip offering cushioning, sealing, and vibration damping. | Good shock absorption, flexibility, and sealing; lightweight. | Lower strength and durability than solid silicone; may absorb liquids. |
| Self-adhesive Silicone | Solid or sponge silicone with a pressure-sensitive adhesive backing for easy installation. | Easy application; no additional adhesives needed. | Adhesive may degrade over time or in extreme temperatures; limited reusability. |
| Food-Grade Silicone | Meets FDA regulations for contact with food products. | Safe for food contact; suitable for food processing equipment and packaging. | May have limited chemical resistance compared to other grades. |
| Medical-Grade Silicone | Meets biocompatibility standards for medical applications. | Safe for medical use; suitable for medical devices and implants. | More expensive than other grades. |
| High-Temperature Silicone | Designed to withstand extremely high temperatures. | Excellent heat resistance. | May be less flexible than other types. |
