ELANTAS RN-1501

Main features

  • Heat-Reduced Resin Viscosity
  • Three-Minute Meter-Mix Window
  • High-Elongation Cast Elastomer

Product Description

CONATHANE RN-1501 Liquid Urethane Prepolymer is a PTMEG polyether liquid urethane prepolymer for producing flexible cast elastomers. Typical viscosity decreases from 17,000 cP at 25 deg C to 500 cP at 100 deg C, providing a defined temperature-dependent processing profile. With CONACURE AH-40 at 100/12.5 parts by weight, the system has a 3-minute work life and forms a Shore A 90 elastomer with 7,500 psi tensile strength and 520% elongation. Applications include industrial truck tires, rolls, gears, die pads, and abrasion-resistant belts.

Key features

  • Temperature-Dependent Viscosity: Typical viscosity decreases from 17,000 cP at 25 deg C to 500 cP at 100 deg C.
  • Three-Minute Work Life: The RN-1501 and CONACURE AH-40 configuration has a 3-minute mixed work life.
  • High-Elongation Elastomer: The specified curative system reaches 520% elongation with Shore A 90 hardness.

Applications / Suitable for

  • Industrial truck tires
  • Rolls, gears, and die pads
  • Abrasion-resistant belts

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
