Polyethylene The molecular weight between 700 and 900 is a semi-solid. The molecular weight of 1000 and above is light white waxy solid or flake paraffin or liquid powder. Soluble in water, soluble in many organic soluble Chemicalbook agents, such as alcohols, ketones, chloroforms, glycerides and aromatic hydrocarbons; Insoluble in most aliphatic hydrocarbons and ethers. With the increase of molecular weight, the water solubility, vapor pressure, water absorption and solubility of organic solvent decrease correspondingly, while the freezing point, relative density, flash point and viscosity increase correspondingly. It is thermally stable, does not work with many chemicals, and does not hydrolyze.
use:
1) Contact lens solution. The viscosity of polyethylene glycol solution is sensitive to shear rate and bacteria are not easy to grow on polyethylene glycol.
2) Synthetic lubricants. Ethylene oxide condensation polymer with water. It is used as the ointment base for the preparation of water-soluble drugs, and can also be used as the solvent of acetylsalicylic acid and other insoluble drugs for the preparation of injection.
3) Drug sustained-release and immobilized enzyme carrier. Applying polyethylene glycol solution to the outer layer of the pill can control the diffusion of the drug in the pill to improve its efficacy.
4) Surface modification of medical polymer materials. The adsorption, retention and grafting of amphiphilic copolymers containing polyethylene glycol on the surface of medical polymer materials can improve the biocompatibility of medical polymer materials in contact with blood.
5) Make alkanol contraceptive film.
6) Make hydrophilic anticoagulant polyurethane.
7) Polyethylene glycol 4000 is a osmotic laxative, which can increase osmotic pressure in the intestinal cavity, absorb water, soften and increase the volume of stool, and promote intestinal peristalsis and defecation.
8) Denture fixative. Using polyethylene glycol non-toxic and colloidal, used as a component of denture fixative.
9)PEG4000 and PEG6000 are commonly used to promote cell fusion or protoplast fusion and help organisms (such as yeast) take in DNA during transformation. PEG can absorb water in solution, so it is also used to concentrate solution.
