Product catalog summary
Overview: The document provides technical specifications for Trelleborg's R490 NR sheeting, a high-performance natural rubber product known for its excellent mechanical properties and versatility in industrial applications.
Features: The R490 NR sheeting is made from natural rubber with para quality, offering translucency and superior mechanical properties. It is suitable for manufacturing gaskets, washers, and other industrial components.
Applications: The sheeting is ideal for use in environments with temperatures up to 50°C for water, alkaline, and salt solutions, and up to 20°C for acetones. It is also used in conveyor belts, rubber sleeves, and mineral processing equipment linings.
Advantages: Key benefits include high tensile strength, tear resistance, elasticity, resistance to wear from fine particles, good electrical properties, and resistance to acids, bases, and salts. It offers a good quality-to-price ratio.
Benefits: The product provides functionality, comfort, extended service life, and economic efficiency.
Mechanical, Physical, and Chemical Properties: The sheeting has a density of 1.05 ±0.05 g/cm³, hardness of 45 ±5 Shore A, tensile strength of ≥16 MPa, elongation at break of ≥600%, and tear resistance of ≥25 N/mm. It withstands temperatures from -40 to +85°C and shows minimal changes in properties after ageing tests.
Chemical Resistance: The sheeting has very good resistance to diluted acids and bases, good resistance to concentrated acids and bases, medium resistance to ozone, and is not suitable for oils and hydrocarbons.
Identification and Packaging: The product is unbranded, available in various thicknesses, and packaged in rolls with black polyethylene film. It includes a self-adhesive label for traceability.
Dimensions: The sheeting is available in thicknesses ranging from 1 mm to 25 mm, with a standard width of 1400 mm and varying lengths. Each thickness has a specified weight per square meter and features smooth sides.
