Ylem Technology Inc. is Polybutene-1 manufacturer in Korea.

Polybutene-1* (PB-1) resins are high molecular weight isotactic, semi-crystalline thermoplastic polyolefins produced through the polymerization of butene-1 and ethylene, and/or propylene comonomers.

PB-1 combines the typical characteristics of polyolefins with a unique property mix of high flexibility and outstanding creep resistance over a wide temperature range. Due to a similar molecular structure, PB-1 is very compatible with PP and propylene-based thermoplastic elastomers. It is easily dispersible in PE notwithstanding their limited molecular compatibility.

Benefits and Applications

PB-1 resins are used in customer applications such as easy-open packaging, film modification, hot melt adhesives, polyolefin modification, water heaters and pipe.

Other customer applications include:

• Flexible pressure piping for domestic hot and cold drinking water

• Piping systems for surface heating and cooling

• District heating

• Radiator connections

• Easy-open flexible packaging

• Low seal initiation temperature modification

• Hot melt adhesives

• Polyolefin modification

• Water heaters

• Extruder purging agent
