Rubber products quality is good how to distinguish?

To identify the good and bad silicone rubber products, mainly from the following elements to consider:?

1, elasticity

It is well known that silicone rubber is elastic. The elasticity of silicone rubber products mainly from the movement of silicone rubber molecular chain segments, good silicone rubber products with high elasticity. For the user, the elasticity is the first examination, high elasticity is the basic element of quality silicone rubber products.

2, tensile strength and tear strength

Tear strength of silicone products with high tear strength outstanding resistance to damage, long life, not easily disturbed by the external environment, tear strength of poor silicone products are generally manifested in the process of tearing is easy to crack, so that when the force is rapidly expanding cracking and lead to the destruction of the phenomenon.

3, abrasion resistance

Abrasion resistance is generally expressed as the surface of the silicone rubber products can be subjected to wear and tear ability. Good silicone rubber products general surface rarely due to external factors rubbing off the product surface, does not affect the appearance of the surface, text, color. And poor quality silicone rubber products surface characters are easy to mo off.

4, fatigue resistance

Silicone rubber fatigue damage resistance determines the service life of silicone rubber products. The so-called fatigue damage refers to the fatigue process of some potential defects within the material due to stress concentration gradually formed cracks, and continue to expand until the phenomenon of fracture. So fatigue resistance is also a way to identify the quality of silicone rubber products.
