Crosslinked polymer - Names and Identifiers
Crosslinked polymer - Introduction
Crosslinked polymer is a kind of polymer material, its molecular chains are closely linked by cross-linking structure. This cross-linked structure gives Crosslinked polymer some special properties and applications.
Nature:
1. Strength and rigidity: Crosslinked polymer has high strength and rigidity, which makes it have excellent mechanical properties in many applications.
2. Heat resistance: Crosslinked polymer has high thermal stability and thermal deformation resistance, and can still maintain its shape and performance under high temperature conditions.
3. High chemical resistance: The cross-linked structure makes the polymer more resistant to chemical corrosion and can resist the erosion of solvents, acids and bases.
4. Low water absorption: Crosslinked polymer reduces the penetration of water molecules into its structure, and can prevent swelling and deformation caused by water absorption.
Use:
1. Plastics industry: Crosslinked polymer are widely used in the plastics industry for the manufacture of auto parts, wire and cable insulation materials, piping systems, etc.
2. Medical devices: Crosslinked polymer materials have biocompatibility and corrosion resistance, and can be used in the manufacture of artificial joints, heart stents and other medical devices.
3. electrical and electronic: due to its special insulation properties and high temperature resistance, it is Crosslinked polymer used in electrical and electronic fields such as wire and cable, circuit board, etc.
4. cosmetics, coatings and other industries also have Crosslinked polymer applications.
Preparation Method:
The preparation of Crosslinked polymer usually involves the introduction of a crosslinking agent between the polymer molecular chains to cause a crosslinking reaction to bind the molecular chains tightly together. Some common preparation methods include thermal crosslinking, radiation crosslinking, chemical crosslinking, etc.
Safety Information:
Crosslinked polymer need to pay attention to safety during manufacture and use. Some crosslinkers and reactants may be toxic, so you should follow the relevant safety procedures and wear personal protective equipment when handling. When using products made of Crosslinked polymer, care should be taken to avoid prolonged high temperature exposure to avoid the release of harmful gases or substances. In addition, according to the specific Crosslinked polymer types and uses, you need to know more detailed safety information.
