At the core of electric heating equipment, a material is needed to simultaneously address multiple challenges: heat loss, vibration damage, electrical risks and water vapor erosion. Our regular silicon sponge is precisely the all-round guardian born for this purpose
1.Seal and insulation, locking in energy
With its uniform and independent closed-cell structure, Silicon sponge effectively blocks heat transfer and air convection, significantly enhancing the energy efficiency of the equipment and ensuring that heat is applied to key areas
2.Buffer and shock absorption, protecting the core
Outstanding compressive resilience can absorb and disperse the vibration and shock during the operation and transportation of the equipment, providing soft yet solid protection for the precision heat-generating components
3.Insulating and waterproof, ensuring safety
Good silicon sponge features excellent electrical insulation and a dense waterproof structure. Even in a humid environment, it can effectively prevent leakage and short circuits, ensuring the safe operation of equipment
4.Heat-resistant and durable, capable of withstanding harsh conditions
It can easily handle working temperatures ranging from -60℃ to 200℃, and has strong anti-aging and weather resistance, ensuring long-term stable operation in complex environments
we are original silicon sponge factory
Inner excellence stems from the selection of raw materials
The raw materials of the heart determine the core performance. We carefully select each batch of silicone raw materials to ensure the outstanding high and low temperature resistance, shock absorption and long-term stability of the foam board.
Core technology, independently developed
We(a excellent silicon sponge manufacturer)master the underlying core technology of silicone foaming - the vulcanization system. This means ensuring a high degree of consistency between product batches from the source, providing a solid foundation for your design.
A faster response mechanism
If your application scenario has special requirements for silicone products, please feel free to contact us. Our technical team can provide you with a variety of options
After fifteen years of hard work, Sanpu Silicone is not only participant in the silicone foam industry, but also very important promoter and leader of the development of silicone foam and silicone applications in China
Our high-quality materials are produced in accordance with international standards and have been widely used and highly trusted in various industries.
A powerful manufacturing enterprise
The company has a registered capital of 10 million yuan, a paid-in capital of 10 million yuan, and a designed annual production capacity of 8 million square meters. We have over ten flat vulcanizing machines with independent intellectual property rights.
Rooted in the silicone industrial park
Our roots are planted in the soil where the silicone industry chain is most complete. This means that from raw materials to processes, your supply chain now enjoys a rare "close-up" certainty.
