1,3-ethylene thiourea
C3H6N2S
M.W. : 102
CAS : 96-45-7
EINECS : 202-506-9
PROPERTIES:
NURCHEM ETU-80 is a primary accelerator or a secondary ultra-accelerator for CR (both sulphur-modified and mercaptan-modified types), an accelerator for epichlorhydrin rubber and a booster in EPDM. It provides rubbers with high tensile stress, low compression set, high plasticity and good heat resistance, and increases the modulus after vulcanisation. In association with antioxidants, it provides good resistance to ageing.
NURCHEM ETU-80 shows a good dispersion, little tendency to scorch and a high degree of processing safety. It enables proper vulcanisation to be obtained speedily at
normal vulcanising temperatures (above 140° C).

Compared to a traditional EVM/EP(D)M binder, NURCHEM ETU-80 allows :
l Dust free products with a high level of filtration up to 38 μ.
l Tack free products at room temperature.
l Lower Mooney viscosity, improving quality of dispersion.
l Scrap rate reduction thanks to filtration.
l Wider compatibility with other elastomers.
