Kraton D1183 BT polymer

D1183 BT SIS-grade polymer is suitable for use in many adhesive applications including thermal printing labels, high-temperature-resistant labels and elastic labels. It is suitable for adhesives in hygiene applications and its shear strength is claimed to be particularly good at 37°C.

It can also achieve significantly higher cohesive strength and higher temperature resistance without the use of endblock resins.

Prior to the commercialisation of Kraton D1183 BT, innovators used low-coupled SIS block copolymers to impart softness to end-products. Although they offered improved adhesion on open and porous substrates and good label die-cutting performance, they often lacked cohesion, which hampered their use in applications that required higher shear and temperature resistance. In comparison, D1183 BT is a 40% diblock SIS, which is claimed to show superior performance to low-coupled SIS block copolymers and is therefore the polymer of choice for these applications.
