Potential applications include cell phone, watch, TV and electronic paper displays. LEPs are promising for flat panel displays but further research is still needed to improve efficiency and lifetime.
Poly fuses are polymeric positive temperature coefficient devices that act as self-resetting circuit protection elements. They function as a series element in a circuit that protects against overcurrent by transitioning from a low resistance state to a high resistance state when the trip current is exceeded, reducing current flow. This transition occurs as the polymer heating causes its structure to change from crystalline to amorphous, separating carbon particles and breaking conductive pathways. Once power is removed and it cools, the poly fuse will automatically reset to its original low resistance state.
Synthetic polymers have many applications in biomedical fields such as bone fracture repair, hip joint replacements, ligaments, tendons, contact lenses, sutures, and burn treatments. Polymers are used where biostability is needed for long-term implants, as biodegradable temporary implants, or as water soluble components of blood substitutes. Common polymers used include PMMA, PGA, PCL, silicone, PUs, nylon and polyacrylates which are chosen based on their mechanical properties, biocompatibility and degradation time frame needed for the application. The variety of polymers and their applications in biomedicine has grown tremendously and is expected to continue expanding to improve medical treatments.

Polymer concrete has several advantages over traditional Portland cement concrete including greater resistance to corrosion, cracking, and chemicals. It uses binders like epoxies, resins, or polymers to bind the concrete components together which provides increased strength and flexibility compared to standard concrete. Polymer concrete can be used for projects both large and small due to its availability in liquid or powder form.
This document discusses polyfuses, which are resettable fuses made of PPTC material. Polyfuses provide overcurrent protection and automatically reset after fault conditions. They operate by rapidly increasing resistance when temperatures rise due to excessive current, which decreases current flow. This protects circuits from damage. Polyfuses come in various forms and ratings and offer advantages over conventional fuses like longer life, compact size, and no need for replacement after tripping. They are widely used to protect electronics, appliances, power supplies and more.
Polyfuse is a polymeric positive temperature coefficient thermistor (PPTC) that provides overcurrent protection and automatic restoration in a circuit. It is made from a composite of semi-crystalline polymer and conductive particles formed into thin sheets with electrodes. In normal operation, the polyfuse has low resistance, but it rapidly increases in resistance and trips in response to excessive current to reduce power in the circuit. This trip occurs as current flow causes heating and a change in crystalline structure that separates the conductive particles. Polyfuses have applications in transformer, speaker, battery, and equipment protection.
This document discusses biocompatible polymers. It begins by defining polymers as macromolecules formed from repeating structural units called monomers. Polymers can be classified based on their structure, mode of polymerization, molecular forces, degradability, and source. Biocompatible polymers are synthetic or natural polymers used in contact with living tissue or to replace parts of the body. They must be non-toxic, chemically inert, and able to withstand biological environments. Common applications of biocompatible polymers include tissue scaffolds, drug delivery systems, medical devices, and coatings to improve blood compatibility. Examples of specific biocompatible polymers and their applications are also provided.

This document discusses the improved properties and cost efficiencies of cyclic olefin copolymer (COC) enhanced forming films. It finds that adding COC to forming film structures improves thermoformability and several key properties. Films with 15% or more COC showed significantly less gauge variation during forming, almost no shrinkage or "snapback" of formed cavities, and increased crush resistance compared to films without COC. The addition of COC allows for downgauging of films while maintaining performance, enabling cost savings through reduced material usage. Overall, incorporating COC delivers robust forming performance, dimensional stability, and potential cost reductions for thermoformed packaging applications.

This document summarizes research on blending cyclic olefin copolymers (COC) with polyethylene to improve heat sealing characteristics. COC was found to improve seal strength, increase the sealing temperature window, and enhance hot tack strength when blended with LDPE, LLDPE, and plastomers. The highest improvements were seen with LLDPE and plastomers. COC is more compatible with LLDPE and plastomers than LDPE. Blending high Tg COC at levels above 20% provided seal-through capability to polyethylenes. In conclusion, COC/polyethylene blends can enhance modulus and heat sealing performance for packaging films.
Mobil DTE 832 is a turbine oil designed for use in steam, gas, and combined cycle turbines. It provides excellent thermal and oxidative resistance to protect turbines in severe operating conditions. Its deposit control properties and water separability allow it to be used in both steam and gas turbines individually or together in combined cycle applications. Using a single oil reduces inventory costs and avoids misapplication.
The document evaluates a new water soluble catalyst, Reaxis® C333, in two-component waterborne polyurethane coatings. Testing showed that C333 provided faster dry times and hardness compared to other catalysts. It also demonstrated good storage stability, selectivity for the NCO/OH reaction over NCO/water, and ability to cure under high humidity. The catalyst is soluble in both water and organic media, and provides advantages for 2K WB PU coatings in meeting VOC regulations while maintaining performance.
This document provides information on various gasket materials produced by Donit Tesnit including Grafilit, Doniflon, Micalit, and Doniflex. Grafilit is an expanded natural graphite material with excellent chemical and thermal resistance. It is available in different compositions for varying operating pressures and temperatures. Doniflon is an expanded PTFE material suitable for most media across a wide pH range. Micalit contains mica flakes and resin for high thermal and chemical resistance. Doniflex materials have aramid fibers, graphite, and binders for good chemical and mechanical properties at elevated temperatures. Each material is designed for specific industries and has distinct properties, composition, and technical data.
1) The document describes TacLED-3D, a new material for 3D structuring LED light that is bendable and formable.
2) TacLED-3D has excellent heat dissipation and dielectric properties that allow it to adhere strongly to metal substrates while maintaining high thermal resistance during bending.
3) Testing shows that TacLED-3D maintains high dielectric breakdown voltage even when bent into complex 3D shapes, and it does not develop microcracks like conventional materials. TacLED-3D is presented as a superior solution for 3D LED applications.
