* Low brass is a copper-zinc alloy containing 20 % zinc with a light golden color and excellent ductility ; it is used for flexible metal hoses and metal bellows.

Intermediate cross-link densities transform gummy polymers into materials that have elastomeric properties and potentially high strengths.

Very high cross-link densities can cause materials to become very rigid or glassy, such as phenol-formaldehyde materials.

PEX is a medium-to high-density polyethylene containing cross-link bonds introduced into the polymer structure, changing the thermoplast into an elastomer.

The long polymer chains cross-link during curing, i. e., vulcanizing.

This reaction causes polymers to cross-link into acrylics, urethanes, and epoxies.

When heat is applied the components react and cross-link.

Plant cells walls also contain numerous enzymes, such as hydrolases, esterases, peroxidases, and transglycosylases, that cut, trim and cross-link wall polymers.

Gluten forms when glutenin molecules cross-link to form a sub-microscopic network attached to gliadin, which contributes viscosity ( thickness ) and extensibility to the mix.

The main action of these aldehyde fixatives is to cross-link amino groups in proteins through the formation of CH < sub > 2 </ sub > ( methylene ) linkage, in the case of formaldehyde, or by a C5H10 cross-links in the case of glutaraldehyde.

Ink is exposed to UV radiation where a chemical reaction takes place where the photo-initiators cause the ink components to cross-link into a solid.

The divalency of the F ( ab ') 2 fragment enables it to cross-link antigens, allowing use for precipitation assays, cellular aggregation via surface antigens, or rosetting assays.

When GPIIb / IIIa receptor is dysfunctional, fibrinogen cannot cross-link platelets, which inhibits primary hemostasis.

The resulting modification of mechanical properties depends strongly on the cross-link density.

For example, electron beam processing is used to cross-link the C type of cross-linked polyethylene.

In some cases, though, if the cross-link bonds are sufficiently different, chemically, from the bonds forming the polymers, the process can be reversed.

This feature is critical to omalizumab's pharmacological effects because a typical anti-IgE antibody can cross-link cell surface FcεRI-bound IgE, thereby aggregate FcεRI, and activate mast cells and basophils to discharge the horde of chemical mediators stored in the densely packed sacs inside the cells.

These contain chemical additives which enable them to cross-link and harden into a tougher, more resilient form.

brake lining is cured under mechanical pressure following a heating & cooling curve, heating the friction material up to 450 ° F to " cure " ( cross-link ) the phenolic resin thermoset polymers: There is no melting of the binding resins, because phenolic resins are thermoset, not thermoplastic In this form of fade, the brake pedal feels firm but there is reduced stopping ability.
