	Heat seamable flame retardant roof sheeting with highly crystalline thermoplasticity promoters and method for covering ...
		It is another object of the present invention to provide compositions which have sufficient crystallinity to show thermoplastic behavior during the formation of a seam using both heat and pressure, but which will continue to maintain its flame resistance.
		The highly crystalline thermoplasticity promoters listed in Table I are necessary, when the polymer blend comprises increasing amounts of the halogenated olefin type elastomer having less than 2 weight percent crystallinity.
		It is to be understood that the invention is not limited to the specific types of halogenated olefinic elastomers or thermoplasticity promoters exemplified herein or by the disclosure of other typical halogenated olefinic elastomers provided herein, the examples having been provided merely to demonstrate the practice of the subject invention.

	Vinyl Usage in Medical Plastics: New Technologies (MPB archive, Jul 98)
		Dynamic vulcanization is a technology associated primarily with thermoplastic rubbers, which are partly cross-linked (vulcanized) during their manufacture.
		For flexible vinyls, a reduction in thermoplasticity allows the compositions to be subjected to higher temperatures than are conventional vinyls.
		Moisture-cured vinyls with reduced thermoplasticity for elevated-temperature applications; flexible PVCs, formed via in situ polymerization that contain no liquid extractables; oxygen-scavenging PVC-based compounds; and nonthrombogenic vinyl formulations are all promising technologies that should come to fruition in the near future.

	Synergistic Effect of Coal Blends on Thermoplasticity Evaluated Using a Temperature-Variable Dynamic Viscoelastic ...
		To maximize the conversion of low-quality coal into good coke, we investigated the thermoplasticity of various binary blends of caking coals with slightly or noncaking coals using a dynamic viscoelastic technique with a temperature-variable rheometer.
		With rapid heating, the thermoplasticity of each coal itself increased, and their thermoplastic temperature ranges widened with rapid heating.
		This suggests that blending coal with an overlapping thermoplastic temperature range is important for the synergistic effect, regardless of the heating rate.

		Their structure is characterized by a small proportion of hard segments, in comparison with their content in soft segments.
		These TPUs have another interesting feature: a low melting point in their crystalline zones (50-60ºC), which permits the polymer to be softened or melted at relatively low temperatures for the adhesion process, with sufficient thermoplasticity and surface tack to ensure correct union between substrates of different materials.
		Using the various types of PEARLSTICK® as the basis, many solvent based TPU adhesives can be made with a variety of organic solvents, for subsequent application in various fields.

		Another characteristic of some PVAs understood to be important (or at least useful) when I started binding in the 1970s is thermoplasticity, i.e., they melt under low heat.
		Jade 403 and Elvace both had this property at one time, but I do not know if current formulations retain it as well.

		The Nitrogen content of the Nitrocellulose affects the polymer solubility and its thermoplasticity.
		Solubility in alcohol increase as the Nitrogen content falls while thermoplasticity increase.
		This means that where high alcohol contents are used in a solvent system, low Nitrogen grades of Nitrocellulose will give better solubility than high Nitrogen grades.

	Nitroplasticized amine perchlorate flexible explosives - Patent Review 3976522
		A sheet explosive employing a fine particle size filler in which a portion hereof is replaced by a plasticizer diluent providing castability at moderate temperatures while maintaining high rates of detonation.
		There are a limited number of alternative high explosive compositions that are readily processable, safe to handle, have appropriate high rates of detonation, suitable low critical thickness propagation and with the specific physical properties to qualify as flexible sheet explosives.
		The fabrication techniques are limited to extrusion because of the thermoplastic nature of the binder; the binder thermoplasticity limits the temperature of potential application or use; and the relatively low explosive filler concentration ordinarily required to provide castable systems reduces the detonation rate and/or increases the critical thickness required for detonation propagation.

		Many synthetic fibers are thermoplastic; that is, they melt when heated.
		Mixtures of thermoplastic and non-thermoplastic fibers, such as cotton / polyester blends, tend to behave more like non-thermoplastics since the non-melting cotton can prevent the molten polyester from withdrawing from the flame.
		Also, as thermoplastic fabrics burn, pieces of the flaming material may melt and drop away, in some cases taking the fire with it and the fabric self-extinguishes.
