Core Conclusion: The high failure rate of Rubber
Research and industry experience show that 80% of Rubber products will malfunction. The main problems include rapid degradation, loss of elasticity, and the generation of unpleasant odors. Frequent replacement is required, which not only increases costs but also causes inconvenience. In terms of reliability, it is far inferior to Silicone.
Comparison of Key Dimensions between Rubber and Silicone
| Comparison dimension | Rubber | Silicone |
| Durability | It has a relatively short lifespan and is prone to failure due to usage or environmental factors | It has better durability and can maintain its form and function even after long-term use |
| Temperature resistance | It becomes brittle or deformed at extreme temperatures and loses its original properties | It can withstand extreme cold and heat, and its performance remains stable in high and low temperature environments |
| Environmental resistance | It is greatly affected by UV ultraviolet rays and ozone, and is prone to cracking and aging when used outdoors | Uv-resistant and ozone-resistant, suitable for outdoor scenarios and less likely to be damaged by environmental exposure |
| Safety | The food-grade attribute is not explicitly mentioned, and there is a risk of chemical substance leaching | Mostly food-grade and BPA-free, it is especially suitable for scenarios such as coffee machines and food storage |
| Maintenance cost | It is difficult to clean and prone to staining. Frequent replacement is required and the long-term cost is high | Easy to clean and stain-resistant; Although upfront is costly, its durability makes it more cost-effective in the long run |
| Applicable scenarios | Emphasizing elasticity and shock absorption, it is suitable for basic scenarios without extreme environments | Suitable for scenarios with high reliability requirements such as high/low temperatures, outdoors, and food contact |

Causes and Improvement Directions for the High Failure Rate of Rubber
1.The main cause of failure
Material quality: Low-grade Rubber is prone to premature failure.
Production process: Manufacturing processes that do not follow industry standards affect product stability.
Quality control deficiency: Lack of strict testing leads to faulty products entering the market.
Application mismatch: Rubber with incompatible attributes not selected based on the usage scenario.
Lagging technology: Failing to keep up with the latest technologies and improvement plans in the industry.
2. Improvement suggestions
Give priority to purchasing high-grade Rubber materials.
Standardize the production process and comply with industry standards.
Establish a strict testing and quality control system.
Precisely select the Rubber type based on application requirements.
Keep up with new technologies in the industry and continuously optimize products.
Final Selection Suggestions
If high reliability, long service life and adaptability to complex environments (such as high temperature, outdoor or food contact) are in pursuit, Silicone should be given priority as it offers better long-term cost performance.
If it is only used in basic elasticity and shock absorption scenarios and is not affected by extreme environments, Rubber can be considered, but it needs to accept a higher replacement frequency and a higher risk of failure.
When in doubt, you can first try out small-sized products and make decisions based on your actual usage experience.
