Case Study
We supplied 4000 meters of silicone sponge cords to an automotive OEM in the UAE for EV battery sealing over 3 years. The seals demonstrated thermal stability, weather resistance, and sealing efficiency.
Customization
We design custom dies for unique profiles. Density, color, adhesive backing, and FDA compliance can be tailored. We accept small quantities.
FAQ
1. What is the difference between sponge and solid silicone seals?
Sponge seals are compressible and conform to uneven surfaces, providing effective sealing with low installation force. Solid seals offer higher density and are more rigid.
2. Can these seals be used outdoors?
Yes, silicone sponge is UV-proof and ozone-resistant, making it excellent for outdoor applications.
3. Do you have a case study for EV battery sealing?
Yes, our case study with an automotive OEM in the UAE confirms successful application over 3 years with 4000 meters of seals.
4. What is the minimum order quantity?
We have flexible MOQ; small orders are accepted. Please inquire.
5. Can you provide a sample before ordering?
Yes, samples are available. Contact us for sample requests.
6. What payment terms are available?
We accept T/T, L/C, D/P, and PayPal for low-value orders.
7. How do you ensure product quality in sponge extrusion?
We conduct in-line density monitoring and final dimensional checks. Pre-shipment tests can be arranged.
