TPE, maker-undisclosed elastomer is a thermoplastic elastomer whose makers do not name the elastomer. A maker sells its oyster-shell-based composite for flexible projects in everyday use and calls it compostable. On the H2C it prints at 220–230 °C, and drying is optional, at 50–60 °C for 4 h.

Partly documented Tensile modulus (XY) and tensile strength (XY) rest on 1 product each and tensile strength (Z), notched Charpy impact and price are not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar. Products with an added filler or additive are shown but kept out of the medians.

Among the materials

Among the materials, TPE, maker-undisclosed elastomer has a high elongation at break (XY) and a low tensile modulus (XY), tensile strength (XY) and density: each is in the top or bottom quarter of the materials that publish it.

TPE, maker-undisclosed elastomer is stiffer than TPU 95A class, TPU 85A class and softer and TPU 90A class and others but is weaker flat than TPU 95A class, TPU 85A class and softer and TPU 90A class and others

What makers say about printing it

Moisture sensitivity

  • Store in airtight container with desiccant, out of direct sunlight. Nanovia ISTROFLEX, data sheet, p. 1

Adhesion between layers

  • Nanovia Istroflex is characterized by a very good build plate and inter layer adhesion. Nanovia ISTROFLEX, data sheet, p. 1
More from makers: printing advice and odour and emissions

Printing advice

  • For a bettter print result, a lower retraction speed is recommended. Nanovia ISTROFLEX, data sheet, p. 1

Odour and emissions

  • We recommend printing Nanovia TPE 22D in a room equipped with air extraction or by using appropriate breathing equipment. Nanovia TPE 22D, data sheet, p. 1
