Working with TPE-S (SEBS) ESD
Is TPE-S (SEBS) easy to machine?
Rarely machined — gummy and low-modulus; use very sharp, high-rake or water-jet/die cutting, and freeze or support thin sections.
Can TPE-S (SEBS) be welded?
Joins well by hot-plate, hot-air and ultrasonic (soft grades damp ultrasound); best practice is 2K injection overmolding, and PP-carrier grades bond only to PP/PE unless a polar-compatible grade is chosen.
Can TPE-S (SEBS) be formed, bent or molded?
Injection mold at 170–230 °C melt with 15–50 °C tool, dry 2–3 h at 60–70 °C if hygroscopic additives are present; large shrinkage (1–3 %) and generous gates/vents for soft grades; also extrudes and blow molds.
What surface finishes work on TPE-S (SEBS)?
Surface is defined by the tool texture — cannot be polished or painted reliably; pad printing and laser marking work with proper pretreatment, and matte EDM texture hides flow marks best.
TPE-S (SEBS) chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

TPE-S (SEBS) ESD is typically used for soft-touch grips, overmolding on PP/ABS, medical device components, cable/wire jacketing and sealing gaskets. In short: most common overmoulding TPE; weather-resistant styrenic TPE; available to Shore 00-30.
What is the tensile strength of TPE-S (SEBS) ESD?
TPE-S (SEBS) ESD has a typical tensile strength of 6 MPa (0.87 ksi) — weaker than 82% of polymer grades. Strength varies by condition: see the 13 listed tempers.
Is TPE-S (SEBS) ESD easy to machine?
Not especially — machinability is rated poor (25/100, worse than 93% of polymer grades). Rarely machined — gummy and low-modulus; use very sharp, high-rake or water-jet/die cutting, and freeze or support thin sections.
Can TPE-S (SEBS) ESD be welded?
Yes — weldability is rated very good (70/100). Joins well by hot-plate, hot-air and ultrasonic (soft grades damp ultrasound); best practice is 2K injection overmolding, and PP-carrier grades bond only to PP/PE unless a polar-compatible grade is chosen.

What is the maximum service temperature of TPE-S (SEBS) ESD?
TPE-S (SEBS) ESD is rated for continuous use to about 85°C (185 °F), and briefly to 120°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
