An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus (E) ...
TPEs are used where conventional elastomers cannot provide the range of physical properties needed in the product. These materials find large application in the automotive sector and in household appliances sector. For instance, copolyester TPEs are used in snowmobile tracks where stiffness and abrasion resistance are at a premium.
TPU is the right choice when flexibility at low temperatures and/or an abrasion resistant thermoplastic elastomer (TPE) is requested. Polyether-based TPU in cases where additional excellent hydrolysis and microbial resistance is required, as well as in cases where extreme low-temperature flexibility is important.
A new class of synthetic rubber is the thermoplastic elastomers which can be moulded easily unlike conventional natural rubber vulcanized rubber. Their structure is stabilized by cross-linking by crystallites in the case of polyurethanes or by amorphous domains in the case of SBS block copolymers .
EPDM rubber (ethylene propylene diene monomer rubber) [1] [2] [3] is a type of synthetic rubber that is used in many applications. EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers with a saturated polyethylene chain (the M deriving from the more correct term
Applications include artificial muscles (prosthetics), mini- and microrobots, and valves. Diaphragm actuators: A diaphragm actuator is made as a planar construction which is then biased in the z-axis to produce out of plane motion. Shell-like actuators: Planar elastomer films are coated at specific locations in the form of electrode segments.
Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.
Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations.
