What is SEBS SHA60?
SEBS SHA60 is SEBS heat treated to SHA60 — workhorse hardness for handle grips, seals and cable jackets needing better abrasion and set than the very soft grades. SEBS SHA60 has a tensile strength of 7 MPa (0.943 ksi), weaker than 82% of polymer grades. Elongation at break is 650% and the elastic modulus is 0 GPa (5.8×10⁻⁴ Msi). SEBS SHA60 has a density of 0.89 g/cm³ (0.0322 lb/in³), lighter than 83% of polymer grades. Its glass-transition temperature is -55°C (-67 °F).

Working with SEBS SHA60
Is SEBS easy to machine?
Poor — the material smears and deflects; die-cutting, waterjet or cryogenic trimming beats milling, and sharp uncoated blades with air blast are required for any cutting.
Can SEBS be welded?
No solvent or HF welding; hot-plate and ultrasonic joints are weak, so 2K overmolding, heat staking to a rigid substrate, or cyanoacrylate/hot-melt adhesive after plasma treatment is preferred.
Can SEBS be formed, bent or molded?
Injection mold at 190–230 °C melt, 20–50 °C tool, low back pressure and generous gates; dry 2–3 h at 60–70 °C if hygroscopic additives are present, and expect 1–2.5 % shrinkage with 2–3 % typical demold recovery.
What surface finishes work on SEBS?
Cannot be painted or plated reliably without adhesion primer; appearance comes from tool texture, in-mold color masterbatch, or anti-tack/soft-touch surface additives to reduce dust pickup.

SEBS SHA60 is typically used for soft-touch grips and overmolds, medical tubing compounds, wire and cable jacketing and adhesive formulations. In short: UV-stable SBS replacement; soft-touch overmold standard; shore A 30-90 compounds.
What is the tensile strength of SEBS SHA60?
SEBS SHA60 has a typical tensile strength of 7 MPa (0.943 ksi) — weaker than 82% of polymer grades. Strength varies by condition: see the 15 listed tempers.
Is SEBS SHA60 easy to machine?
Not especially — machinability is rated poor (25/100, worse than 93% of polymer grades). Poor — the material smears and deflects; die-cutting, waterjet or cryogenic trimming beats milling, and sharp uncoated blades with air blast are required for any cutting.
Can SEBS SHA60 be welded?
Yes — weldability is rated good (55/100). No solvent or HF welding; hot-plate and ultrasonic joints are weak, so 2K overmolding, heat staking to a rigid substrate, or cyanoacrylate/hot-melt adhesive after plasma treatment is preferred.

What is the maximum service temperature of SEBS SHA60?
SEBS SHA60 is rated for continuous use to about 85°C (185 °F), and briefly to 110°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
