FAQ
Q: What is High density silicone sponge?
A: High density silicone sponge is a kind of special silicone sponge with different forumula ,whose density is slight higher than the conventional silicone sponge but whose wear resistance is much better.
Q2: How is the price of high density silicone sponge?
A: High density silicone sponge's price is higher than conventional silicone sponge .Because the cost of this microprous silicone sponge is higher than conventional silicone sponge .
Q3: What is Lead Time of high density silicone sponge?
A: 5-15 working days after the payment.
Q4: How do you ensure product quality?
A: 1.We use high-quality raw materials 2.We have strict inspection procedures
Q: Can you supply these wear resistant pads with high-temperature adhesive backing?
A: Yes. We apply industrial-grade pressure-sensitive adhesives (PSA) directly to the silicone sponge surface during post-processing. For high-temperature applications up to 200°C, we utilize glass-fiber reinforced acrylic adhesives. For applications approaching 260°C, we offer specialized silicone-based adhesives to ensure permanent bonding without delamina
