Definition

Noun: 1. A synthetic polymer: A thermoplastic polymer or resin made by polymerizing butylene. It is characterized by properties such as flexibility, toughness, and resistance to creep and stress cracking. 2. An industrial material: This material is used in various applications, notably in plumbing systems for pipes and fittings, as well as in lubricants and synthetic rubber formulations.

Usage Examples

• General Use:
  • The plumber recommended using polybutylene pipes for the new bathroom installation.
  • This grease contains polybutylene to improve its viscosity and performance.
• Technical/Scientific Context:
  • The study compared the long-term durability of polybutylene to other thermoplastic polymers.
  • Polybutylene is synthesized via the polymerization of butene-1.

Advanced Usage

• In Material Science: The term is often used when discussing polymer properties, manufacturing processes, or material failure analysis.
  • The research paper analyzed the molecular degradation of polybutylene in oxidizing environments.
• In Industry Specifications: Frequently appears in technical data sheets, material standards, and building codes.
  • The specification requires that all tubing must be made from grade 1 polybutylene.

Variants and Related Words

• Polybutene (n): A very closely related term, often used interchangeably in some industrial contexts to refer to polymers of butylene, particularly lower molecular weight oils used as lubricants or adhesives.
• PB (n): A common abbreviation for polybutylene, especially in plumbing and piping industries (e.g., PB pipe).
• Polymer (n): The general class of large molecules to which polybutylene belongs.
• Thermoplastic (n/adj): A category of plastics, including polybutylene, that become moldable when heated.

Synonyms

• Polybutene (in specific contexts, see Variants above)
• PB polymer

Related Phrases and Compounds

• Polybutylene pipe: A specific application referring to piping used for potable water distribution and hydronic heating systems.
  • Many homes built in the 1980s have polybutylene pipe plumbing.
• Polybutylene terephthalate (PBT): A different, engineering thermoplastic polyester. Important: This is a distinct material and not a variant of polybutylene itself.
