■What is Polybutene? It is a synthetic resin produced by polymerizing "butene-1," featuring a helical structure with ethyl groups in the side chains. With a molecular weight of approximately 1.2 million, it has excellent heat creep resistance and stress crack resistance. ★Excellent Durability Due to its superior heat creep resistance, there is almost no reduction in strength even when used at high temperatures for extended periods. ★Excellent Insulation and Refrigeration Properties With a low thermal conductivity, it excels in maintaining the temperature of fluids within the pipes. ★Hygienic, Safe, Clean, and Reliable This safe pipe does not cause water quality contamination due to rust, and it is resistant to the occurrence of red water and scale buildup. ★Lightweight, Flexible, and Easy to Install Being lightweight and flexible, along with its long pipe length, it is easy to handle and does not require threading or other complex processing, making installation simple.

basic information
<Properties of Polybutene Pipes> ■ Lightweight and suitable for water supply and hot water Can be used for both hot water and cold water. This makes it easy to share components and manage inventory. ■ No special work required when cutting the pipe Can be easily cut with a dedicated pipe cutter. ■ Excellent wear resistance, impact resistance, and stress cracking resistance Highly resistant to wear, difficult to break under strong impacts, and exhibits excellent stress cracking resistance against water hammer and thermal expansion. Additionally, its flexibility enhances workability. ■ Excellent heat creep resistance Due to its ultra-high molecular weight, it has excellent heat creep resistance, making it durable for high temperatures (below 95°C) such as in hot water applications. ■ Excellent thermal insulation and condensation prevention It excels in thermal insulation for hot water and condensation prevention on the pipe surface for cold water. It is even more effective when used in a sheath or with insulated pipes. ■ Hygienic and highly safe Polybutene pipes do not cause water quality contamination due to rust. Additionally, there is no leaching of harmful substances, allowing for safe use.

Applications/Examples of results
Using polybutene pipes... ◎ No worries about rust, long-lasting! "Polybutene" is a resin material that does not rust like metal pipes, is hygienic, and can be recycled. Even in the event of an earthquake, it is less likely to break compared to traditional metal pipes due to its flexibility. *Recycled polybutene resin can be used for binders (covers), clear files, saddles, etc. ◎ Reduction of water hammer The flexible material absorbs the water hammer that occurs when a faucet is closed, reducing noise generation.
