Natural rubber is a versatile material that is used in various industries for its unique properties. One of the most popular forms of natural rubber is Ribbed Smoked Sheet (RSS). In this article, we will explore what RSS is, its grades, and its uses.
What are the Grades of RSS Rubber?
Ribbed Smoked Sheets, commonly known as RSS, are graded into RSS1 to RSS5, with RSS1 being the top grade. These sheets are usually packed in large bales weighing 1111kg/bale or 19 metric tons per 20-foot FCL.
The different grades of RSS are determined by the percentage of particles present in the rubber sheet. Here are the acceptable conditions for each grade:
RSS1
- Oxidized spots, weak heated, under-cured, over-smoked, opaque, and burnt sheets are not acceptable.
- Slight traces of dry mold on the packaging are acceptable, but mold should not penetrate inside the bale.
- Small scattered pinhead bubbles are permissible.
RSS2
- Oxidized spots, weak heated, under-cured, over-smoked, opaque, and burnt sheets are not acceptable.
- Slight traces of rust and dry mold on the packaging and interior sheets are acceptable, but it should not exceed 5% of the bales sampled.
- Small bubbles and slight specks of bark are permissible.
RSS3
- Oxidized spots, weak heated, under-cured, over-smoked, opaque, and burnt sheets are not acceptable.
- Slight traces of rust and dry mold on the packaging and interior sheets are acceptable, but it should not exceed 10% of the bales sampled.
- Small bubbles, slight specks of bark, and slight blemishes in color are permissible.
RSS4
- Oxidized spots, weak heated, under-cured, over-smoked (exceeding the degree shown in samples), opaque, and burnt sheets are not acceptable.
- Slight traces of rust and dry mold on the packaging and interior sheets are acceptable, but it should not exceed 20% of the bales sampled.
- Medium-sized black particles, bubbles, translucent stains, slightly sticky or over-smoked rubber are permissible.
RSS5
- Oxidized spots, weak heated, and burnt sheets are not acceptable.
- Slight traces of rust and dry mold on the packaging and interior sheets are acceptable, but it should not exceed 30% of the bales sampled.
- Large particles, bubbles or barks, small stains or blisters, slightly sticky, slightly under-cured or over-smoked rubber, and blemishes are permissible.
What is the use of Natural Rubber Sheet?
Natural rubber sheets, including Ribbed Smoked Sheets, have various applications in different industries. Here are some common uses:
- Tire Manufacturing: RSS rubber is a key component in tire production. Its excellent elasticity, strength, and resistance to wear make it an ideal material for tire treads.
- Automotive Industry: Natural rubber sheets are also used in various automotive parts, such as seals, gaskets, and vibration dampers. Its flexibility and durability contribute to the overall performance and longevity of these components.
- Construction: Natural rubber sheets find applications in the construction industry for roofing, flooring, and insulation purposes. Its water resistance and insulation properties make it a popular choice for these applications.
- Industrial Machinery: RSS rubber is used in the manufacturing of belts, hoses, and seals for industrial machinery. Its high tensile strength and resistance to chemicals and abrasion make it suitable for these demanding applications.
- Medical Industry: Natural rubber sheets are utilized in the production of medical gloves, catheters, and other medical devices. Its hypoallergenic properties and flexibility make it safe and comfortable for medical use.
Ribbed Smoked Sheets (RSS) are a high-quality form of natural rubber that is used in various industries. The different grades of RSS ensure that only the best quality sheets are used for specific applications. From tire manufacturing to medical devices, natural rubber sheets play a vital role in numerous products and industries.
