Product Description

Rubber Seal Ring Silicone Foam Seal Custom Flame Retardancy Auto Parts O Ring Seal Silicone Gaskets 


Here are the 30% differences:


1. Enhanced Resilience:

Silicone foam insulation showcases outstanding resilience, surpassing conventional materials in battery protection. It has been subjected to rigorous testing, enduring over 10,000 cycles of compression with minimal deformation, exhibiting a change of less than 3%. This exceptional rebound capability ensures long-term reliability, effectively safeguarding NEV batteries throughout their operational lifespan.


2. Advanced Comprehensive Protection:

In addition to insulation, silicone foam insulation offers advanced features such as dustproofing, waterproofing, heat dissipation, shock absorption, and vibration damping. These properties are critical for NEV battery protection systems, shielding the battery pack from external contaminants, preventing moisture ingress, efficiently managing heat dissipation, and minimizing the impact of vibrations and shocks. This comprehensive protection contributes significantly to the overall performance, safety, and durability of NEV batteries.


3. Enduring Performance in Harsh Conditions:

Silicone foam insulation undergoes extensive testing to evaluate its performance under extreme environmental conditions. Data from stress relaxation tests conducted at 85°C and 90% relative humidity for 1,500 hours reveals that the material exhibits a stress relaxation rate of only 15.62%. This exceptional result demonstrates its ability to maintain mechanical integrity and provide consistent performance, even in the most demanding situations. NEV batteries can rely on silicone foam insulation to deliver unwavering protection in challenging operating conditions.


4. Exceptional Compression Resistance:

Silicone foam insulation demonstrates outstanding resistance to crushing, retaining its shape and performance even after prolonged use. The material exhibits an impressively low compression set, ranging from 0.2% to 0.5% in a 20,000-belt 1 million compression cycle test, ensuring its long-lasting durability and effectiveness in safeguarding new energy vehicle batteries. These results highlight the material's superior resilience and its ability to maintain shape and performance over an extended period. NEV batteries benefit from the exceptional durability provided by silicone foam insulation.


5. Minimal Moisture Absorption:

Silicone foam insulation boasts an incredibly low moisture absorption rate of only 0.2%. This characteristic is crucial for NEV battery protection, as it ensures the material remains stable and unaffected by moisture. The minimal moisture absorption rate prevents any adverse effects on the battery pack's performance, even in highly humid environments. It further reinforces the material's suitability for NEV applications.


As the new energy vehicle industry continues to evolve, silicone foam insulation emerges as the ultimate choice for battery protection and thermal management systems. Its enhanced resilience, advanced comprehensive protection features, enduring performance in harsh conditions, exceptional compression resistance, and minimal moisture absorption differentiate it from traditional materials. Silicone foam insulation plays a pivotal role in enhancing NEV battery performance, safety, and lifespan. Its numerous advantages make it a compelling solution that should be widely adopted in the NEV industry, driving innovation and ensuring the continued success of new energy vehicles.

High-Performance Silicone Gaskets 
With their ability to withstand temperatures as high as 450°F and as low as -75°F, gaskets made from silicone rubber are highly versatile. You can find these gaskets used in a number of applications, including food processing, medical equipment, automobile engines, aerospace, pharmaceutical, energy, mobile technologies, and more. Silicone gaskets also offer excellent electrical insulation, durability, resistance to high pressures, and are flame retardant. Available in a range of colour options, these gaskets are also commonly chosen for their aesthetic value.

Compare & Contrast: Silicone vs. EPDM

Silicone and EPDM are similar in many ways, and the two materials offer a variety of similar characteristics. Both offer good resistance to weathering, UV exposure, and ageing, making them suitable for outdoor applications. Silicone and EPDM also exhibit high ozone resistance and an ability to remain flexible in low temperatures.

However, silicone provides far greater high-temperature resistance. Unlike EPDM, silicone will maintain its stability and physical properties in temperatures as high as 450°F (232°C).
