Why Is Seal Material Important for Pneumatic Systems?

The material of a pneumatic seal directly impacts its durability, wear resistance, Dan compatibility with different environments.

Incorrect material choices can result in:

  • Keausan dini dan kebocoran
  • Swelling or hardening karena paparan bahan kimia
  • Reduced efficiency and costly downtime

That’s why understanding when to use Bahasa Inggris, TPU, atau FKM is essential for achieving optimal system performance.

What Is NBR and Why Is It Used in Pneumatic Seals?

NBR is the most common material for pneumatic seals, valued for its affordability, fleksibilitas, Dan oil resistance.

Key Advantages of NBR Seals:

  • Ketahanan yang baik terhadap minyak dan lemak
  • Terjangkau dan mudah diproduksi
  • Fleksibel pada suhu rendah (-30°C hingga 100°C)
  • Tahan terhadap keausan umum

Best Applications for NBR Seals:

  • Silinder pneumatik serbaguna
  • Sistem udara bertekanan rendah
  • Industrial automation in moderate conditions

📌 Common NBR Seals: Segel Poros QYD, Segel Piston PZ, Segel Debu DOP

Why Should You Use TPU for Pneumatic Seals?

TPU seals excel in high-wear environments karena mereka excellent abrasion resistance Dan mechanical strength.

Key Advantages of TPU Seals:

  • High abrasion resistance for extended life
  • Excellent flexibility and elasticity (-40°C to 90°C)
  • Tahan terhadap cairan dan oli hidrolik
  • Ideal for high-speed movement with low friction

Best Applications for TPU Seals:

  • Silinder pneumatik berkecepatan tinggi
  • Mesin industri tugas berat
  • Sistem suspensi dan pengereman otomotif

📌 Common TPU Seals: Segel Piston DPRS, PP Kaifu Buffer Seal, Segel Debu EM

Why Is FKM Ideal for High-Temperature Pneumatic Seals?

FKM is perfect for lingkungan yang keras where seals face extreme temperatures, chemicals, Dan aggressive fluids.

Key Advantages of FKM Seals:

  • Tahan terhadap suhu tinggi (-20°C hingga 250°C)
  • Ketahanan kimia yang sangat baik (bahan bakar, pelarut, asam)
  • Umur panjang dalam kondisi ekstrim
  • Menangani lingkungan bertekanan tinggi

Best Applications for FKM Seals:

  • Industri kedirgantaraan dan kimia
  • Pneumatic systems exposed to high temperatures
  • Sealing in aggressive chemical environments

📌 Common FKM Seals: Segel Piston Tipe Y E4, QYD Rod Seal, Segel Debu ZHM

NBR vs. TPU vs. FKM – Mana yang Harus Anda Pilih?

Each material has unique strengths suited for different applications:

Fitur NBR (Karet Nitril) TPU (Poliuretana) FKM (Karet Fluorokarbon)
Kisaran Suhu -30°C hingga 100°C -40°C hingga 90°C -20°C hingga 250°C
Ketahanan Aus Sedang Tinggi Tinggi
Ketahanan Kimia Sedang Bagus Bagus sekali
Tahan Minyak Bagus Bagus sekali Bagus sekali
Terbaik Untuk Sistem pneumatik serba guna Aplikasi kecepatan tinggi Paparan suhu tinggi & bahan kimia

📌 Use NBR for standard applications, TPU for high-wear, and FKM for extreme environments.
