Tired of sealing failure & melting under high heat? Our engineered Sponge Silicone Mat delivers outstanding sealing AND withstands 280℃ for 72H without compromise.
You need a specially formulated sponge silicone mat built for extreme heat and consistent sealing performance.
Core Advantage: New-Grade Sponge Silicone Mat
High elongation up to 300% Excellent flexibility and wear resistance, allowing heavy stretching without cracking or breaking.
Extreme temperature stability After exposure to 280℃ for 72 hours(536°F for 72 hrs), its elongation remains above 120%, maintaining elasticity, without deformation,which means it have good sealing performance.
Closed cell structure Closed-cell , means it is low water absorption, good resilience, and reliable sealing performance.
Safe & eco-friendly Non-toxic, odorless, RoHS compliant, suitable for electronics, automotive, packaging, and high-temperature equipment.
Datasheet Of New-Grade Sponge Silicone Mat
fAQ
Q1: How is this different from regular sponge silicone mats?
A: Our formula is specially compounded for 280℃/72H heat stability. Most standard sponge silicone fails above 200℃ with hardening and sealing loss. Ours maintains elasticity and sealing under extreme heat.
Q2: Does it stay sealed when stretched or compressed?
A: Yes. High resilience and low compression set ensure excellent sealing performance in both tension and compression - ideal for gaps, doors, panels, and high-vibration equipment.
Q3: Can you cut or customize size & shape?
A: Yes. We provide sheets, rolls, and custom die-cut gaskets or back adhesive per your drawing (CAD/PDF accepted).
Q4: Is it safe for contact?
A: Yes. it is safe to touch and non-toxic, odorless, no pollution.
Q5: What's the lead time & MOQ?
A: Standard sheets: 3–7 working days. MOQ starts at 1 sheet(if we have stock). Custom sizes/molded parts: 7–15 days.
Q6: Will it deform after long-term compression?
A: No. Compression set ≤5% - maintains shape and sealing for years without flattening.
Q7: Where is your factory ?
A: Building 1, No. 19, Junhao South Road, Ninghua County, Sanming City, Fujian Province
Q8:Do you have foreign trade business experience?
A: Yes ,we started our foreign business 5 years ago .we have export license too.
