TPE 101 By: Jonas Angus President & Founder TPE Solutions, Inc. Jonas Angus, TPE Industry Expert For more than 25 years, Jonas Angus, Founder of TPE Solutions, Inc., has been a leader in innovative Thermoplastic Elastomer (TPE) solutions. Now you can put his expertise to work for your company. TPE Solutions, Inc. is a private, consulting and procurement firm dedicated to helping clients select or formulate the most affordable TPE solution that meets the performance requirements of their application. Why TPE TPEs provide the similar advanced performance properties to thermoset rubber, but can be processed with the speed and economy of thermoplastics. With unlimited end-use characteristics for the hottest consumer products (protection, color, feel, grip, softness, a feeling of quality and substance) TPEs can be found in a wide array of consumer and industrial applications. If you are currently manufacturing or designing a new rubber part, and want to capitalize on the economy of thermoplastic processing, then TPEs could be a viable option. Bottom Line: TPEs offer a cost effective alternative to traditional rubbers. TPEs ? Broad range of Terms TPRR SIS What is a TPE? • TPE is an elastomer that is processed into final articles with equipment used for thermoplastics, such as injection molding, blow molding, extrusion, compression molding, thermoforming. • TPE generally has two phases, soft and hard. The transition temperatures of these phases determine the service temperature range of TPE. • TPE processing characteristics depend upon softening, or melting, of the rigid thermoplastic phase. • TPE products are typically very shear sensitive during processing. • TPE products are recyclable and colorable. Classes of TPEs Five Major Classes 1) Thermoplastic Polyurethane (TPUs) 2) Styrenic Block CoPolymers (SBCs) 3) Thermoplastic Vulcanizate (TPVs) 4) Thermoplastic Olefins (TPOs) 5) Engineered TPEs (COPEs, COPAs, MPR, ETPV, TPVs) History of TPEs 1) TPUs • Discovery Period: 1937 to 1958 • Commercialization: 1959 • Pioneers: Otto Buyr, C.S.
