What is tpr material?
Thermoplastic Rubber (TPR)
What is an amorphous thermoplastic?
Amorphous = without form; without its own form; can apply to any substance that can be easily molded into various shapes. Thermoplastic = synthetic substance that can be extruded and/or molded at a higher temperature and will assume and keep the form desired as it cools. Ideally, it should remain in the desired form at a normal room-temperature range. Example: high- or low-density polyethylene (HDPE or LDPE), the substance used to make such things as zipper-closeable bags (usually LDPE) or those ubiquitous super-thin shopping/grocery bags (HDPE), and numerous other smooth translucent plastic objects.
Where does plastic come from?
Thermoplastic, also known as a thermosoftening plastic,[1][2] is a polymer that turns to a liquid when heated and freezes to a rigid state when cooled sufficiently. Most thermoplastics are high-molecular-weight polymers whose chains associate through weak Van der Waals forces (polyethylene); stronger dipole-dipole interactions and hydrogen bonding (nylon);[3] or even stacking of aromatic rings (polystyrene). Thermoplastic polymers differ from thermosetting polymers (e.g. phenolics, epoxies) in that they can be remelted and remoulded. Many thermoplastic materials are addition polymers; e.g., vinyl chain-growth polymers such as polyethylene and polypropylene; others are productions of condensation or other forms of polyaddition polymerisation, such as the polyamides or polyester.
How is sulfur used in tires?
natural rubber is thermoplastic (which when heated-up become soft). When this natural rubber is heated with sulphur, the properties of this rubber are improved. 1. it becomes non-sticky. 2. it gains ahigh tensile strength. 3. it can be used over awide range of temperature (-40C to 100C). so can resist heat produced due to friction. 4. it has high wear and tear resistance.
Is polyurethane a plastic?
Polyurethane formulations cover an extremely wide range of stiffness, hardness, and densities. These materials include: * Low-density flexible foam used in upholstery and bedding * Low-density rigid foam used for thermal insulation and RTM cores * Soft solid elastomers used for gel pads and print rollers * Hard solid plastics used as electronic instrument bezels and structural parts Polyurethanes are widely used in high resiliency flexible foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires, automotive suspension bushings, electrical potting compounds, high performance adhesives and sealants, Spandex fibers, seals, gaskets, carpet underlay, and hard plastic parts. source: http://en.wikipedia.org/wiki/Polyurethane

What is the difference between alkyd latex and waterborne alkyd?
Traditionally, alkyds are found in solvent-based paints that must be reduced with paint thinner or mineral spirits. "Waterborne alkyd" is a generic term to refer to an alkyd resin that can be used in a water-thinnable paint. Because alkyds are not miscible with water, a chemical modification is sometimes used to produce a hybrid alkyd resin - often acrylic/alkyd or urethane/alkyd - that is compatible with water. These hybrids are often categorized generically under the term waterborne alkyds. A pure alkyd can be emulsified in water using appropriate surfactant combinations. This type of surfactant-stabilized alkyd emulsion has been sometimes referred to as an "alkyd latex." Different resin manufacturers use varying terminology to describe waterborne alkyds with the terms alkyd emulsion, alkyd dispersion, and alkyd latex being among the most common.
