Why Yutian foam silicone tube

🐝

Closed cell micro‑cellular structure

Independent tiny air pockets – lightweight & elastic

Uniform closed cells provide excellent cushioning, thermal insulation, and waterproof sealing. No moisture absorption.

→ Reliable in humid environments

🔄

Outstanding compression recovery

Compression set ≤15% (70°C×22h)

Returns to original shape after repeated compression. No permanent deformation, long‑term sealing reliability.

→ Low maintenance, less replacement

🌡️

Wide temperature & aging resistance

-40°C to +200°C · no embrittlement

Resists heat, cold, UV, and ozone. Does not crack or yellow over time.

→ Suitable for outdoor and high‑temp applications

🔇

Noise reduction & thermal insulation

Low thermal conductivity (0.04‑0.08 W/m·K)

Effective sound dampening and heat barrier. Ideal for HVAC, machinery enclosures.

→ Energy saving, quieter operation

📏

Fully customizable

ID 1‑100mm · density 0.3‑0.8 g/cm³ · hardness 10‑40 Shore C

Custom size, closed/open cell, food/industrial grade. Low MOQ, fast sampling.

→ Tailored to your application

Frequently asked questions

Is the foam silicone tube closed cell or open cell?

Standard is closed cell – independent air pockets provide waterproof sealing and thermal insulation. Open cell available on request for breathable applications.

What is the compression recovery performance?

Compression set ≤15% (70°C×22h). Excellent rebound after repeated compression – ideal for dynamic sealing.

What temperature range can it handle?

Continuous -40°C to +200°C. No embrittlement or softening. Special high‑temp formula available.

Is it waterproof? Suitable for outdoor use?

Yes, closed cell structure blocks moisture. Resists UV, ozone, and weathering – long outdoor life.

Can you customise density and hardness?

Absolutely. Density 0.3‑0.8 g/cm³, hardness 10‑40 Shore C. Tailored to your cushioning or sealing needs.

What is the typical lead time for custom orders?

Stock 2‑4 days. Custom samples 5‑7 days, mass production 7‑10 days after approval.
