Global Elastomeric Alloys Market: Overview
Elastomeric alloys fall under the category of thermoplastic elastomers. An elastomeric alloy is a blend of a thermoplastic and an elastomer. However, they possess significantly superior properties compared to conventional blends, as they are manufactured by using specialized thermoplastic processing methods. Typically, an elastomeric alloy contains polymer alloys of rubber and an olefinic resin. Commercially available elastomeric alloys are thermoplastic vulcanizates (TPVs), melt-processible rubbers (MPRs), and thermoplastic olefin (TPO).

Global Elastomeric Alloys Market: Drivers & Restrains
Elastomeric alloys can be utilized as an alternative material in several applications of silicone, latex, or rubber. They can be processed with the help of the conventional processing methods such as blow molding, extrusion, and injection molding. Elastomeric alloys are ideal materials in applications, wherein elastic properties are required. Elastomeric alloys are available in varying ranges of hardness and tensile strength. Typically, they are available in the hardness range of 55A to 50D, and in the tensile strength range of 800 psi to 4,000 psi.
Among elastomeric alloys, thermoplastic elastomers (TPEs) have advantages such as ease of processing and higher speed over the conventional thermoset (vulcanized) alloys. A few other advantages are lower energy costs for processing, availability of standard grades (which lacks in case of thermoset alloys), and recyclability of scrap. Availability of standard grades of TPEs is a particularly crucial advantage for several manufactures.
The market for elastomeric alloys has been witnessing growth since the late 1900s. For instance, Monsanto Chemical Co. commercialized a line of TPVs in 1981 under the brand name Santoprene. The alloy was based on polypropylene (PP) and ethylene propylene diene monomer (EPDM) rubber. It was designed in comparison with thermoset rubbers for applications in middle performance range. The company launched another TPV alloy composed of PP and nitrile rubber, under the brand name Geolast, in 1985. The product was designed to offer higher oil resistance than that of EPDM-based material. As the product offered oil resistance comparable to that of thermoset nitrile and neoprene, Geolast could be used as a replacement for thermoset nitrile and neoprene.
