Temperature resistance of materials
The temperature resistance of materials is an important parameter that is often overlooked when purchasing rubber products. The performance differences of different types of rubber in high and low temperature environments can be quite significant. For example, silicone rubber has better stability in high temperature environments than natural rubber, while natural rubber performs better in terms of toughness at low temperatures. Therefore, considering the specific usage environment is crucial.
Hardness level
The hardness of rubber products directly affects their functionality and applicability. Shore hardness testers are commonly used to measure the hardness of rubber, but many purchasers often only focus on the basic hardness range, failing to understand the impact this has on product performance. For instance, higher hardness may mean better wear resistance, but it can also lead to reduced toughness, thus affecting service life.
Chemical resistance
In industrial applications, rubber products often need to come into contact with various chemicals, including oils, acids, and alkalis. The differences in chemical resistance among different rubber materials are significant, and purchasers must carefully consider this when making selections. For example, fluorocarbon rubber exhibits excellent corrosion resistance against many chemicals, while ordinary natural rubber may degrade rapidly.
Processing compatibility
Sometimes, those purchasing rubber products overlook the processing compatibility of the materials. Certain rubbers may encounter issues during subsequent processing, such as bonding or molding difficulties. Understanding the processing performance of different rubber materials helps reduce unexpected occurrences during production and the associated cost increases. This parameter is particularly important in composite material applications.
Aging performance
During use, the aging performance of rubber will directly affect its service life. Failing to adequately consider aging factors during procurement may lead to product failure in a short period. The aging of rubber is mainly influenced by environmental factors (such as oxygen, ultraviolet light, and humidity), so choosing rubber materials with good aging resistance can effectively extend the product's service life.
