In many cases, the discharge end of the feed throat is near or even above the polymer's melting or softening point
, even with water cooling.
SBS content in Polymer Modified Bitumen (PMB) asphalt is about 4.5% by mass (the dosage is chosen to reach a minimum softening point
of 54 [degrees]C).
Federal claims the softening point
of its Slipstream is 434 degrees, high enough to resist heat-instigated change and deliver consistent long-range flight.
The high-temperature performance and low-temperature performance of silica fume/SBS composite-modified asphalt mortar were evaluated by the cone penetration, softening point
, viscosity, DSR, and BBR.
Ring and ball ([SP.sub.R&B]) softening point
was determined according to EN 1427.
were the subscripts "ag" and "or" indicate aged and original, respectively, while P is a generic property, such as penetration, viscosity, softening point
, ductility, and complex modulus.
In asphalt roofing, Ceranovus waxes can be used to stabilize or increase the softening point
of commercial, residential or peel-and-stick roofing products while decreasing penetration in desired formulations.

The Vicat softening point
of the billet sample was measured on a 3 mm disk sample cut from the billet.
However, West Yorkshire-based Dugdale says its newly developed formulations now also enable its manufacturing customers to fully comply with the BS 5255: 1989 specification for waste thermoplastic fitting of wall thickness less than 2.7 mm--wherein a Vicat Softening Point
requirement of > 80 degrees Celsius is mandatory.
Most resin suppliers categorize products according to softening point
from 100[degrees]C to 140[degrees]C.
