Polybutene-1 (PB-1) resins from LyondellBasell have diverse applications, including easy packaging, film modification, hot melt adhesives, polyolefin modification, hot water tanks, and pipes and fittings. This material is lightweight and offers excellent performance characteristics such as creep resistance, outstanding flexibility over a wide temperature range, low noise transmission, and good thermal fusion properties.

PB-1 grades are processed using various techniques, including extrusion, extrusion blow molding, and injection molding. PB-1 resins are available as both homopolymer and random copolymers. PB-1 is a high molecular weight, linear, and semi-crystalline polymer. It combines the typical properties of conventional polyolefins with specific characteristics of engineering polymers.

Environmental impact of Polybutene-1

Polybutene-1 (PB-1) is a polyolefin-based polymer that is generally considered environmentally stable. It does not release harmful substances during its lifecycle and is fully recyclable. PB-1’s durability and long service life contribute to reduced material waste, particularly in applications like piping and industrial packaging.

Safety Measures and Regulations for Handling Polybutene-1

PB-1 is considered a low-risk material in terms of toxicity and health hazards. It does not produce harmful emissions under normal conditions and is safe for food contact applications. However, during processing, exposure to high temperatures may release fumes, requiring adequate ventilation. Proper personal protective equipment (PPE), such as gloves and safety goggles, should be used when handling molten PB-1 to prevent burns.

Packing

packaging includes 25 kg bags, big bags, or bulk shipments.
