Product Description
Polybutene is a liquid copolymerized primarily of isobutylene and a small amount of n-butene. Its structure consists almost entirely of long chains and includes a single double bond. There is no strict distinction between polybutene and low-molecular-weight polyisobutylene in their use, as their preparation methods are essentially the same, making strict differentiation difficult. However, polybutene is made from mixed butenes and structurally is a copolymer of isobutylene and n-butene. It has a lower molecular weight and is a viscous liquid, primarily used as a synthetic lubricant. Low-molecular-weight polyisobutylene, on the other hand, is made from high-purity isobutylene and structurally is a homopolymer of isobutylene. It is semi-solid and generally has a higher molecular weight than polybutene, primarily used as a thickener. Low-molecular-weight polybutene, due to its absence of waxy substances, possesses excellent electrical properties and is widely used as an electrical insulating oil. Because it completely decomposes at around 300℃ without leaving residue, it can be used as a base component in high-temperature, carbon-free lubricating oils. It is widely used in two-stroke engine oils, electrical insulating oils, lubricants, coolants, and cylinder oils for ultra-high-pressure compressors in the production of low-density polyethylene.
What are the benefits?
1. Excellent Temperature Resistance:
Can be used long-term within a temperature range of -30℃ to 110℃. It exhibits outstanding resistance to heat creep, is not easily deformed at high temperatures, and maintains flexibility and resilience at low temperatures, preventing brittleness.
2. Excellent Resistance to Environmental Stress Cracking:
Compared to other polyolefin materials, it is less prone to cracking under long-term stress or humid environments, making it suitable for applications requiring high durability, such as pipes and packaging.
3. High Toughness and Impact Resistance:
The material is soft and tough, able to withstand significant impacts without easily being damaged, making it suitable for pipes, containers, and other applications requiring impact resistance.
4. Strong Chemical Stability:
It exhibits good corrosion resistance to acids, alkalis, salt solutions, and various organic solvents. Stress cracking only occurs under the action of strong oxidizing agents such as concentrated sulfuric acid and fuming nitric acid, making it suitable for equipment in chemical and medical fields.
5. High Hygiene and Safety:
Non-toxic, tasteless, and odorless, it is difficult for microorganisms to grow, meeting hygiene standards for drinking water transportation and food and pharmaceutical packaging. It can be used in infant bottles, medical devices, etc. 6. Lightweight and Flexible: Low density and light weight facilitate handling and installation; good flexibility and a small minimum bending radius allow for easy pipe laying in confined spaces or complex terrain, reducing the need for bends and lowering construction costs.
7. Energy Saving and Environmentally Friendly:
When used in underfloor heating systems, its low thermal conductivity and excellent insulation performance can save approximately 30% of energy; the material is recyclable, and its combustion products are non-corrosive and non-toxic, meeting environmental protection requirements.
8. Easy to Process and Connect:
Integrated connections can be achieved through methods such as heat fusion, ensuring good sealing at the joints and preventing leakage; excellent processing performance allows for the production of various shapes of products such as pipes, films, and containers.
