Abstract:
A siphon tube having a polymeric material into which at least one continuous reinforcing agent is embedded, and wherein the at least one reinforcing agent runs substantially the length of the siphon tube. The polymer material can be one or more polymers selected from one or more high density polyethylenes, one or more polyamides, and one or more fluoropolymers.
Abstract:
An improved process comprising treating monofilaments with high temperatures to deorient the surface. A preferred product is a heavy denier transparent polyamide monofilament, especially suitable as fishing line.
Abstract:
Marine umbilicals are provided comprising polyamide compositions having good hydrolysis resistance and that may optionally contain plasticizer.
Abstract:
A process for producing plasticized polyamide blends containing additives such as tougheners, reinforcing agents, and/or filler. High average molecular weight plasticized blends containing additives may be made using the process of the invention. Pipes and tubing may be made from the blends prepared using the process of the invention.
Abstract:
Novel fishing lines, and related products, especially monofilamentary products, of polyesters that are biodegradable and disintegrate, when immersed over a period of weeks or months in water, to avoid residues thereof obstructing the aqueous environment, but are storage-stable, i.e.. do not disintegrate while being stored in air, before such lengthy immersion.
Abstract:
A pipe or comprising a melt-mixed blend of polyamide and incompatible polyolefin and a compatibilizing agent where the polyamide exists as a discontinuous phase that is dispersed in a polyolefin matrix and wherein nanoclay is exfoliated in the polyamide phase. The pipe has enhanced resistance to the permeation of hydrocarbons relative to polyethylene. A method for making a pipe having enhanced resistance to the permeation of hydrocarbons.
