A leak detection system including a sensor having a first state having a first condition when dry and a second condition when wet, and a second state adapted to monitor the operability of the sensor; a communication device operatively connected to the sensor; and an attachment element adapted to attach the leak detection system to a fluid component for monitoring fluid leakage.

Leak detection system and method of making and using the same

A leak detection system including a sensor having a first condition when dry and a second condition when wet; a communication device operatively coupled to the sensor; and an attachment element adapted to attach the leak detection system to an area for monitoring fluid leakage, wherein the attachment element is removable, reusable, or both.

Leak detection system with electronics component

The present disclosure relates generally to flexible tubing, for example, suitable for use in peristaltic pumps. The present disclosure relates more particularly to flexible tubing having a stable flow rate despite being extruded from thermoplastic polymer and methods for making such tubing. In one aspect, at least 50% of the material volume of a flexible tubing of the disclosure is formed from a first polymer material that includes a continuous phase that includes polypropylene and a non-cross-linked styrene block copolymer elastomer miscible with the polypropylene, as well as, dispersed within the continuous phase (e.g., discontinuously dispersed within the continuous phase), a cross-linked rubber phase. The non-cross-linked styrene block copolymer elastomer is present in the first polymeric material in an amount in the range of 2 wt % to 15 wt %. In certain desirable embodiments of the flexible tubings described herein, the flexible tubing has a flow rate variation over the 480 hours of use of less than 20%.

Flexible tubing having a stable flow rate and methods for making and using it

Leak detection system

A multilayer flexible tube includes an inner layer including a melt processable fluoropolymer, wherein the fluoropolymer includes a copolymer of a poly vinylidene fluoride (PVDF) and a hexafluoropropylene (HFP); and an outer layer including a melt processable polymer having a shore hardness less than a shore hardness of the inner layer, wherein the multilayer flexible tube has a maximum storage modulus of at least 300 MegaPascal (MPa) at a temperature of about &#x2212;10&#xb0; C.

Multilayer flexible tube and methods for making same

A polyester or polyester copolymer based composition, such as a polylactic acid based composition, is provided herein. The polyester or polyester copolymer based composition may include a plasticizer, such as an ether based, an ester based, and/or an ether-ester based plasticizer.

Stabilized polyester based compositions

A multilayer flexible tube includes an inner layer including a melt processable fluoropolymer, wherein the fluoropolymer includes a copolymer of a poly vinylidene fluoride (PVDF) and a hexafluoropropylene (HFP); and an outer layer including a melt processable polymer having a shore hardness less than a shore hardness of the inner layer. Further provided is a method of making the multilayer flexible tube.
