polybutylene
Học thuậtThân thiện
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
