A polyester composition includes, based on the total weight of the polyester composition, a first polyester and a second polyester, wherein a weight ratio of the first polyester to the second polyester is 80:20 to 20:80, preferably 60:40 to 40:60; 5 to 60 weight percent (wt %), preferably 5 to 50 wt % of a reinforcing filler; and 5 to 60 wt %, preferably 10 to 50 wt %, more preferably 20 to 50 wt % of an inorganic filler having a specific gravity of greater than 3 grams per cubic centimeter, as determined in accordance with ASTM D792, wherein a molded article comprising the polyester composition has a sound transmission loss of greater than 30 dB, preferably 35 to 50 dB, more preferably 36 to 45 dB, as determined at 1,250 Hz according to ASTM E1050 using a molded disc with a diameter of 100 mm and a thickness of 3.2 mm.

The present invention relates to a thermosetting resin composition. The composition comprises from about 20 wt. % to about 70 wt. % of a thermosetting resin, from about 1 wt. % to about 30 wt. % of a curing agent, from about 0 wt. % to about 10 wt. % of an accelerant, a tungsten compound, and an inorganic filler. A prepreg may be prepared in an impregnation manner or a coating product may be prepared in a coating manner. The composition may decrease the thermal expansion coefficient of laminates and may effectively block UV light and decrease the light transmissivity.

The present disclosure describes a gastric jejunal tube having a gastric lumen and a jejunal lumen that run the length of the tube. The cross-sectional sizes of the lumens change from above to below the most distal gastric port. A method of making the gastric jejunal tube is also described.

An object of the invention is to provide a radiation-shielding material that has a high radiation-shielding capability and can be easily coated, molded and sheeted. Metals or the like having a radiation-shielding capability are blended with an elastomer precursor in a high concentration thereby providing a radiation-shielding material that has a higher radiation-shielding capability than ever before and can be easily coated, molded and sheeted in any desired configuration.

The present invention relates to a metal-filled resin formulation, more particularly for a 3D printing method, on the basis of layer-by-layer photopolymerization for the manufacture of a component, wherein the resin formulation contains a photopolymerizable matrix component, a dense metal filler having a specific minimum volume fraction, and a photoinitiator. A component is additively manufactured by the layer-by-layer selective curing of the metal-filled resin formulation by means of irradiation with light. The invention in particular relates to the high-precision manufacture of radiation-absorbing components on the basis of lithographic additive processes such as SLA; because of the special choice of the formulation used, wall thicknesses down to less than 100 m are possible while still achieving good radiation hardness and good surface quality.

Disclosed are composite cables suitable for use in conjunction with wellbore tools. One cable may include a polymer composite that includes dopants dispersed in a polymer matrix and continuous fibers extending along an axial length of the cable through the polymer matrix, wherein the cable is characterized by at least one of the following: (1) at least a portion of the cable having a density greater than about 2 g/cm.sup.3, wherein at least some of the dopants have a density of about 6 g/cm.sup.3 or greater, (2) at least a portion of the cable having a density less than about 2 g/cm.sup.3, wherein at least some of the dopants have a density of about 0.9 g/cm.sup.3 or less, (3) at least some of the dopants are ferromagnetic, or (4) at least some of the dopants are hydrogen getters.

A composition and method for spray-applying a two-part, self-setting composition containing a dopant that provides a hazard shielding component and is particularly adapted for delivering the components of the composition at a temperature that promotes their spray application as well as a self-setting reaction. The method includes selecting a self-setting compound that is adapted for curing in place once applied, the self-setting compound including at least one dopant material; and applying the compound to a hazard to be encapsulated such as a radiological, lead, asbestos, or PCB. Alternately, a self-curing compound includes a multi-part compound which, upon a mixing of the parts, chemically reacts and cures, and at least one dopant material dispersed into at least one of the parts, wherein the dopant material is selected for providing radiation shielding upon application of the compound.

A bullet (ammunition projectile) comprising a branched condensation polymer and a filler, wherein the filler is present in an amount from about 10% to 65% by volume of the branched condensation polymer and filler is described. The bullet may be made by heating a mixture comprised of a branched condensation polymer and a filler comprised of a first and second filler having differing densities and differing particle size distribution to form a molten mixture and injecting the molten mixture into a mold to form the ammunition projectile allowing for the tailoring of the characteristics of the bullet for differing applications.
