Polymer-bonded explosive. Polymer-bonded explosives, also called PBX or plastic-bonded explosives, are explosive materials in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer. PBXs are normally used for explosive materials that are not easily melted into a casting ...
Hydroxyl-terminated polybutadiene ( HTPB) is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup. The properties vary because HTPB is a mixture rather than a ...
In anti-scratch coatings, binders (coatings' glue-like cohesive structure) provide scratch resistance or/and provide structure for scratch resistant additives and filters. Binders that offer scratch resistances and structure include: Ceramic-(Inorganic-non metal-based) binders; Polysilazanes; Diamond-like Carbon; Resin (organic polymer-based ...
Plastic consumption uses by field. Filler materials are particles added to resin or binders ( plastics, composites, concrete) that can improve specific properties, make the product cheaper, or a mixture of both. [1] The two largest segments for filler material use is elastomers and plastics. [2] Worldwide, more than 53 million tons of fillers ...
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. [1]
Polymer concrete. Polymer concrete, also known as Epoxy Granite, is a type of concrete that uses a polymer to replace lime -type cements as a binder. In some cases the polymer is used in addition to Portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [1] Polymers in concrete have been overseen by Committee ...
A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion . More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it ...
The process steps involve combining metal powders with polymers such as wax and polypropylene binders to produce the "feedstock" mix that is injected as a liquid into a mold using plastic injection molding machines. The molded or "green part" is cooled and ejected from the mold.
Furan resins serve as binders for the casting moulds. Furan resin refers to polymers produced from various furan compounds, [1] of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan rings are not connected by conjugation. The resins are generally used as binders for ...
Plastic spiral binding is a three-step process: punch, insert, crimp. [citation needed] First, a punch creates holes along the edge of the document. Second, a coil inserter spins the coils through the holes. Third, a pair of coil crimping pliers or a crimping machine is used to cut off the excess coil and crimp the end to prevent the coil from ...
