Thickness - The thickness of the sheet is very important, depending on what it is used for. For example, the thickness of the plate is very important when choosing gaskets and oil seals
Temperature - The rubber sheet will be exposed to a specific temperature; These temperatures are the most important. If the temperature is too high for the rubber to handle, it will melt. On the other hand, if the temperature falls below its minimum tolerance, the rubber will begin to crack.
Wear resistance - The resistance of rubber to rubbing, scraping or erosion should be considered
Ozone and UV resistance - Many types of rubber break down when exposed to ozone and UV light and need to be checked.
Oil resistance - Rubber is usually affected by oils and other liquids, so when choosing a rubber sheet, its oil resistance should be considered.
Acid resistance - Not every rubber is acid resistant.
Hardness - The chemical structure of an elastomer provides an inherent hardness that can be changed. The enhanced hardness was then measured with Duro on a Shaw hardness tester. Check the hardness of the rubber before choosing it, especially for sealing purposes. Tensile strength - Tensile strength is the force required to tear a rubber sample until it breaks. It is also known as ultimate tensile strength and is measured in megapascals or pounds per square inch (psi) according to ASTM D412 specification. Tensile strength is an important factor for designers and buyers because it highlights the point of failure caused by the maximum stretch of rubber.
Tensile modulus - Tensile modulus is the stress or force required to produce strain or elongation in a rubber sample. It may sound similar to tensile strength, but its properties are quite different. Hard rubber has a higher tensile modulus, which makes it more elastic. It is crush resistant.
Elongation - REFERRED to as the percentage or strain increase in the original length of the rubber sample when a stress or tensile force is applied. Some elastomers tend to stretch more than others.
Compression permanent deformation - Compression permanent deformation is the extent to which the elastomer refuses to restore its initial thickness after the release of the compression load. The continuous compression of rubber seals leads to a stress relaxation process over time. Permanent compression deformation is the final result of the continuous decrease of sealing force.
Specific gravity - Is the ratio of the weight of a material to the weight of the same volume of water at a given temperature. This property makes it easy for chemists to identify compounds. The most important thing for technology buyers and part designers to realize is that lower weight rubber provides more square inches per pound of stock. In contrast, those with a higher proportion have more advantages in terms of forming consistency.
Abrasion resistance - Is the abrasion resistance of rubber to rubbing or scraping.
Wear- Resistant rubber can be used in industrial applications, such as pumps to process mud and conveyor belts to move coal.
