Materials: Extended Line of Nylon-Based TPEs

An extended product family of nylon-based TPEs, also known as polyether-block-amides (PEBA) is newly availble from Nylon Corporation of America, Inc. (NYCOA), Manchester, N.H.

An extended product family of nylon-based TPEs, also known as polyether-block-amides (PEBA) is newly availble from Nylon Corporation of America, Inc. (NYCOA), Manchester, N.H. Targeted to a range of applications in the automotive, sporting goods, personal electronics, composite, and specialty film materials, the Ny-Flex elastomer range is positioned as a new and innovative class of engineering TPEs (E-TPEs). Available in hardness from 82 Shore D to 90 Shore A, they have lower specific gravity compared to TPUs and are easily processed using thermoplastic processing techniques.

Characterized by a nylon block which is the hard segment and the polyether block which is the soft, flexible segment, NyFlex grades are, as such, hybrid materials that boast a unique combination of rubber-like elastomeric properties and thermoplastic-like processing capabilities. By varying the type and the ratio of these two blocks, a wide range of grades are offered and are said to deliver a broad range of benefits including excellent flexibility at low temperature, superior retention of properties to elevated temperature, and exceptional toughness and resilience. High creep resistance, strong resistance to flex fatigue, good abrasion resistance, and superior resistance to greased, oils, and solvent are also claimed.

AM Powder Designed to Create Conformal Cooling Channels

With so much happening in a busy show year between NPE2018, Amerimold 2018 and IMTS 2018, MoldMaking Technology is revisiting some of the technology that was on display. In case you missed it: Uddeholm says that using Corrax additive manufacturing powder enables the creation of conformal cooling channels to reduce cycle times. The company had the powder on display at NPE2018.
