Why Yutian flame retardant foam silicone tube

🔥

UL94 V-0 certified – true fire safety

Self-extinguishing · no dripping · low smoke

Meets the highest industry flame rating. Stops burning immediately after flame removal – no melted drips, low smoke emission. Perfect for high‑risk applications.

→ Fire safety compliance, peace of mind

🔄

Outstanding cushioning & compression recovery

Compression set ≤15% · soft yet resilient

Closed cell foam structure absorbs impact and vibration. Returns to original shape after repeated compression – ideal for battery cushioning and seals.

→ Long‑term protection, less maintenance

🌡️

Wide temperature & aging resistance

-40°C to +200°C · ozone & UV resistant

No hardening, no cracking. Resists heat aging, ozone, and UV – stable in harsh environments.

→ Reliable for outdoor and engine compartments

⚡

Excellent electrical insulation

High dielectric strength · waterproof · dustproof

Closed cell structure blocks moisture and dust, while providing high insulation resistance. Safe for electronic and EV applications.

→ Protects sensitive electronics

📏

Fully customizable

ID 1‑80mm · density 0.3‑0.7 g/cm³ · hardness 10‑40 Shore C
