Abstract:
A metallized optical fiber comprises: A) An optical fiber, and B) A conductive metal over and in contact with the optical fiber and having a thickness that is at least 0.15 times the thickness of the optical fiber. The metallized optical fiber can form a component of a hybrid optical fiber/coaxial cable, and it provides good protection against interference with the data signal traveling along the optical fiber from electrical current from an adjacent or near-by electrical conductor.
Abstract:
The present disclosure is directed to a plasticizer composition, polymeric compositions containing the plasticizer composition, and conductors coated with the polymeric composition. The plasticizer composition includes a first plasticizer comprising epoxidized fatty acid alkyl esters and a second plasticizer comprising an epoxidized natural oil. The plasticizer composition, first plasticizer, and/or second plasticizer can undergo one or more color-reducing treatment processes, such as distillation, filtration, and/or peroxide treatment.
Abstract:
The present disclosure is directed to a composition and articles containing the composition. The composition includes an ethylene-propylene-diene interpolymer (EPDM) having a rheology ratio greater than 33. The EPDM also has a molecular weight distribution greater than 3Ø The composition has a dissipation factor less than or equal to 0.01 radians as measured in accordance with ASTM D 150 (130°C, 60 Hz).
Abstract:
The present disclosure is directed to a plasticizer, polymeric compositions containing the plasticizer, and conductors coated with the polymeric composition. The plasticizer includes (i) an epoxidized fatty acid methyl ester, (ii) an epoxidized natural oil, and (iii) an epoxidized tallate ester. Polymeric compositions containing a polymeric resin and the plasticizer exhibit a weight loss less than 50 mg/cm2 after exposure to 100°C for seven days. Conductors coated with the polymeric composition (containing the plasticizer) pass the low temperature unwind test of UL719 and exhibit a weight loss less than 50 mg/cm2 after exposure to 100°C for seven days.
Abstract:
Disclosed is a halogen-free, flame retardant thermoplastic resin composition based on polypropylene and one or more thermoplastic elastomers with an organic nitrogen- and/or phosphorus-based intumescent flame retardant comprising a piperazine component. The composition is processed easily to make a wire and cable sheath exhibiting a balance of high flame retardancy, good flexibility, high wet electrical resistance and excellent heat deformation properties, and which passes the VW-I flame retardancy test, the UL1581 heat deformation test at 150 °C and the wet electrical resistance test, and also exhibits good tensile and flexibility properties. Also disclosed is a wire and cable sheath made from the composition.
