SBR RUBBER GASKETS Physical properties
SBR rubber gaskets have good elasticity and recovery properties and can return to their original shape after being stressed, providing an effective sealing effect.
It has good resistance to compression deformation and can withstand certain pressure and deformation without losing sealing performance.
It has certain wear resistance and can maintain a long service life under conditions such as contact friction and extrusion.
SBR rubber gaskets remain flexible and elastic under low temperature conditions and are suitable for applications in low temperature environments.
SBR (styrene-butadiene rubber) material is often used to make rubber gaskets. The following is a description of some of its physical and chemical properties.
chemical properties
Oil resistance: It has good oil resistance to some common industrial oils and lubricants.
Solvent resistance: S can resist erosion and damage from certain solvents.
Acid and alkali resistance: It has certain tolerance to some weak acids and weak bases, but it may not be suitable for acid and alkali solutions with higher concentrations.
Application scope
SBR rubber gaskets are often used at flange connections to provide a sealing effect and prevent leakage.
They can be used at connection points, valves and pumps in pipeline systems to ensure sealing performance.Also are widely used in general industrial fields, such as machinery and equipment, automobile manufacturing, hydraulic systems, etc.
Common mechanical equipment application scenarios of SBR (styrene-butadiene rubber) rubber gaskets are as follows;
Vibration Isolation: Vibration isolation systems that can be used for mechanical equipment. They are placed at the base or supporting feet of mechanical equipment to reduce the transmission of vibration to the ground or other structures to reduce noise and the impact of vibration on the equipment and the surrounding environment.
Shock absorption and noise reduction: SBR rubber gaskets are used in key parts such as bases, brackets, and vibration absorbers to absorb shock and reduce noise generated when the equipment is running. They absorb and reduce mechanical vibration and shock, providing a smoother operating environment.
Sealing and waterproofing: SBR rubber gaskets can be used for sealing parts of mechanical equipment, doors, covers, seams, etc. They prevent the entry or leakage of liquids, gases or particles and protect the internal components of mechanical equipment from damage or corrosion.
Gaskets and gaskets: Used as gaskets or gaskets in mechanical equipment to fill and fill gaps in joints to ensure a tight connection and prevent leakage. They are often used for sealing and fixing in bolt, flange, and pipe connection applications.
Impact-absorbing pad: It can also be used as an impact-absorbing pad for mechanical equipment to reduce or eliminate the risk of damage to mechanical equipment when it is impacted or overloaded. They are placed under mechanical parts, structures or connection points to absorb and disperse impact forces, protecting the stability and durability of the equipment.
Certification for SBR RUBBER GASKETS
Certification standards for SBR (styrene-butadiene rubber) rubber gaskets may vary by region and specific application.
Here are some common rubber gasket certification standards, some of which may apply to SBR rubber gaskets:
ASTM standards: American Society for Testing and Materials (ASTM), ASTM D2000 (Rubber Products Material Classification System) and ASTM D1056 (Rubber Foam, Sponge and Cell Filling Materials), etc.
ISO standards: International Organization for Standardization (ISO) ISO 13000 series (terminology for rubber and rubber products), ISO 732 (rubber, latex or plastic gaskets), etc.
DIN standards: German Institute for Standardization (DIN), such as DIN 7715(Rubber and rubber products – Technical specifications for sealing materials) and DIN 28091-1(Non-metallic gaskets – Part 1: General technical delivery conditions), etc.
ANSI standards: American National Standards Institute (ANSI); such as ANSI/NAAMM FG 1000 (metal gasket) and ANSI/NAAMM FG 251 (rubber gasket), etc.
BS standards: British Standards Institute (BSI); such as BS 2494 (rubber gaskets) and BS EN 1337-3 (rubber gaskets for structures), etc.
SBR rubber gaskets may not be suitable in certain special chemical media, high temperatures or harsh environments. When selecting and using SBR rubber gaskets, users should evaluate their applicability based on specific working conditions, media properties and requirements, and follow relevant standards and specifications.
