CROSSLINKING of rubber and polyolefins with organic peroxides Chemical crosslinking agents such as sulphur and organic peroxides are able to link polymer chains creating a three-dimensional network. This crosslinking reaction changes several Typical amounts of organic peroxides required material characteristics.
Effect of Ionic Crosslinking Agents on Swelling Behaviour of Chitosan Hydrogel Membranes The swelling behaviour of the ionic hydrogels is unique. It is affected by the ionization of functional groups along the polymer chains and the ionization of crosslinking agent molecules.

Cross-linking agent synonyms, Cross-linking agent pronunciation, Cross-linking agent translation, English dictionary definition of Cross-linking agent. n. A chemical bond formed between adjacent chains of a complex molecule such as a polymer.
Cytec Industries has introduced Cylink 2000 crosslinking agent, a formaldehyde-free resin that is ideal for applications requiring exterior durability and acid etch resistance. The new carbamate functional resin is recommended for high-quality, solventborne and waterborne thermosetting finishes.
Crosslinking AgentsX Crosslinking is the formation of chemical links between molecular chains to form a three-dimensional network of connected molecules. The vulcanization of rubber using elemental sulfur is an example of crosslinking, converting raw rubber from a weak plastic to a highly resilient elastomer.
Crosslinking is the process of chemically joining two or more molecules by a covalent bond. The technique, often called bioconjugation when referring to its use with proteins and other biomolecules, is an essential component of many proteomics methods, including creation of detectable probes for ...
CrossLink is the industry's leading provider of professional tax software solutions for high-volume retail tax businesses that specialize in providing their clients with fast and accurate tax returns.
MECHLORETHAMINE was the 1st alkylating agent to be used clinically. It is a derivative of mustard gas, a chemical warfare agent developed during World War I. Physicians treating soldiers realized that bone marrow suppression was a problem in people who managed to survive the initial vesicant effects.
Hydrophilized Crosslinking Agent In order to improve cohesion, adhesion and thermal stability after application, aqueous adhesives can be combined with water-dispersible crosslinking agents. The Basonat ® range sold by BASF includes such systems, which facilitate the development of both aqueous two-component adhesives and the formulation of ...
Crosslinking Agents. For high performance polyethylene applications, requiring higher temperature, creep, abrasion and chemical resistances, crosslinking is a must. Of all the crosslinking technologies, Silane is the one which exhibits the greatest process flexibility and superior mechanical performance.
The crystal nature of the crosslinking agents minimizes when they are melted with the virgin polyethylene due to the absence of the melting property thus affecting the market negatively. Crosslinking Agents Market: Regional Analysis. The regions that are dominating the crosslinking agents market are Western Europe and North America.
Reactivity. D-1011 readily hydrolyzes upon contact with moisture.. Application and performance. D-1011 is transported from the production site as the parent silane to formulators.
Question: Is there a CPT code for corneal cross-linking? Answer: The CPT code for cross-linking is Category III code 0402T. The code has no relative value units assigned to it. Thus, most payers may not cover this service and the patient will be responsible for payment. Do not bill 0402T in conjunction with CPT codes 65435, 66990 or 76514.
Agent means as a kind of monomer on the so-called stated in aggregate into the molecular chain structure of National People's Congress, or as a component added to the adhesive, can stable storage, only when heated to a certain temperature or radiation condition that crosslinking reaction to happen.
New crosslinking agent also has advantages in the application in textile industry. Perfume bottle or glass coating baking restaurants tend to be carried out under the high temperature of more than 180 degrees. Before the traditional crosslinking agent, if at that temperature unlock will appear obvious rehmannia phenomenon.
Their swelling degree increased with the increase of pH of the external medium and an instantaneous increase was observed near a pH value of 7.0. The use of PEG (400) DA instead of NMBA as a crosslinking agent also increased the swelling rate and capacity of the gel.

Although the method does not measure crosslink density as such, an indicator of the degree of crosslinking is the gel fraction remaining after a free film of a coating has been under solvent reflux in a Soxhlet extractor for several hours so that soluble material has been extracted.
Detailed crosslinking protocols (Protein–Protein Crosslinking Kit) The Protein–Protein Crosslinking Kit was designed to prepare and purify protein–protein conjugates; however, it can be readily modified for generating peptide–protein or enzyme–nucleic acid conjugates or for conjugating biomolecules to affinity matrices.
