thermosetting polymer
thermosetting resin

Catalin is a brand name for a thermosetting polymer popular in the 1930s.

The technology is not limited to thermosetting polymers.

There are two types of plastics: thermoplastics and thermosetting polymers.

Monomer is encapsulated and embedded within the thermosetting polymer.

A cured thermosetting polymer is called a thermoset.

Many thermosetting polymers are difficult to recycle.

Thermosetting polymers, for example, are not remoldable.

Additionally, thermosetting polymers cannot be recycled, so it is even more important to extend the lifetime of materials of this nature.

The synthetic resin for such processes is a monomer for making a plastic thermosetting polymer.

As a rule, polysilazane solids behave as thermosetting polymers, but in some cases, thermoplastic processing is possible.

It is most commonly used to process both thermoplastic and thermosetting polymers, with the former being considerably more prolific in terms of annual material volumes processed.

While most polyurethanes are thermosetting polymers that do not melt when heated, thermoplastic polyurethanes are also available.

One consequence of this is that typical polyurethanes do not soften or melt when they are heated...they are thermosetting polymers.

Injection molding can be performed with a host of materials, including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers.

Among synthetic polymers, crystalline melting is only discussed with regards to thermoplastics, as thermosetting polymers will decompose at high temperatures rather than melt.

Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with strong mechanical properties as well as high temperature and chemical resistance.

Soft thermoplastics and metals have moderate elastic deformation ranges while ceramics, crystals, and hard thermosetting polymers undergo almost no elastic deformation.

Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold.

The chemistry involved is similar to epoxy, which is a type of thermosetting polymer that solidifies irreversibly (the precise starting material is bisphenol linked to glycerol at each end).

In this way, thermoplastics differ from thermosetting polymers, which form irreversible chemical bonds during the curing process; thermoset bonds break down upon melting and do not reform upon cooling.

Rubber, Bakelite, urea-formaldehyde copolymers are examples of thermosetting polymers; methyl methacrylate (Plexiglas), polystyrene, polyethylene are examples of thermoplastic polymers.

According to IUPAC recommendation: A thermosetting polymer is a prepolymer in a soft solid or viscous state that changes irreversibly into an infusible, insoluble polymer network by curing.

A wide range of materials has been successfully deposited with the Aerosol Jet process, including diluted thick film pastes, thermosetting polymers such as UV-curable epoxies, and solvent-based polymers like polyurethane and polyimide, and biologic materials.

These prepregs consist of wood fibers and thermosetting resins.

Metallographic specimens are typically "mounted" using a hot compression thermosetting resin.

In 1938 melamine thermosetting resin was developed by American Cyanamid Company.

Such polymers may be useful as coatings or thermosetting resins, often prized for their thermal stability.

When heated in the presence of acids, furfural irreversibly solidifies into a hard thermosetting resin.

Melamine thermosetting resin is developed by American Cyanamid.

Unsaturated polyesters are thermosetting resins.

The method is most often used for composite materials such as reinforced thermosetting resins or to determine how much a resin or plastic has cured.

Fiberglass spoilers consist of fiberglass cloth infilled with a thermosetting resin .

Most commonly a thermosetting resin is used that polymerizes by mixing with a curing agent (polymerization catalyst) at room temperature and normal pressure.

The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms.

J.E. Hanger, Inc. was able to introduce new prosthetic socket designs made from improved materials such as thermosetting resins.

Wood flour is commonly used as a filler in thermosetting resins such as bakelite, and in linoleum floor coverings.

Amino resins are considered a class of thermosetting resins of which urea-formaldehyde resins make up 80% produced globally.

In polymer concrete, thermosetting resins are used as the principal polymer component due to their high thermal stability and resistance to a wide variety of chemicals.

The patent covers panels made of nonflammable material like ceramic, thermosetting resins or sheet metal, 30 to 50 feet high and designed to connect to form a wall.

Masonite, a wood hardboard, was bonded using natural lignin, (although most modern MDF particle boards use synthetic thermosetting resins).

Nanocellulose has been reported to improve the mechanical properties of, for example, thermosetting resins, starch-based matrixes, soy protein, rubber latex, poly(lactide).

The specific code is EN438, entitled: Decorative high-pressure laminates (HPL) sheets based on thermosetting resins, specifications.

In the past, phenolic thermosetting resins have been used, but modern epoxy is becoming more popular because reduced shrinkage during curing results in a better mount with superior edge retention.

Many professional shapers actually outsource the highly specialized lamination to specialized "glassers", one who laminates fiberglass to a foam core of a surfboard using thermosetting resins like polyester or epoxy.

They originally conceived it as a substitute for mica used as electrical insulation, made of wrapped woven fabric coated with Bakelite thermosetting resin, then slit lengthwise, flattened, and cured in a press.

When the form is sculpted in the foam core, the shaper may complete the build by layering fiberglass sheets over the deck and bottom and laminating these with a thermosetting resin such as polyester.

For investigation of the curing behavior of thermosetting resin systems, composite materials, adhesives and paints, Dielectric Analysis (DEA) can be used in accordance with ASTM E 2038 or E 2039.

It also routinely used as a filler in thermosetting resins (sheet and bulk molding compounds) and has also been mixed with ABS, and other ingredients, to form some types of compression molded "clay" poker chips.
