softening point

Upon further heating, they gradually soften, which can be characterized by certain softening points.

The product(s) you find on the store shelf is likely formulated to give a range of softening points depending upon the intended use.

The softening point is the temperature at which a material softens beyond some arbitrary softness.

This raises the softening point so high that in the presence of air (oxygen) it burns before it melts.

It works by bringing up the temperature of the pipe or sheet to the softening point of 176 degrees or higher.

Replies: Probably not except that Polystyrene foam has a low softening point and may collapse if the contents get anywhere near 100C.

The material can be crushed or cut into strips that is heated until the softening point of glass, binding the loose material back into a solid form.

The p-phenylene ring is particularly effective in this respect, but when carried to extremes, produces a highly intractable, rigid structure, poly(p-phenylene) with no softening point.

PVC-U has a softening point as low as 65C, so the guttering could actually be permanently distorted by the heat rising off your conservatory roof.

The bottom layer of the duplicating film (the thermoplastic layer) is heated above its softening point and pressed against the stamper, so that it takes up its shape.

Standards to determine Vicat softening point include ASTM D 1525 and ISO 306, which are largely equivalent.

This secondary welding is most common and suggests that the temperature of most pyroclastic density currents is below the softening point of the particles (Chapin et al. 1979).

It refers to the point beyond the die where the temperature of the molten plastic falls below the softening point and the diameter of the extruded plastic bubble stabilizes.

After reaching the working temperature, which is between the transition temperature and the softening point of the glass, the moulds close further and start pressing the glass in a travel-controlled process.

Vicat softening point or Vicat hardness is the determination of the softening point for materials that have no definite melting point, such as plastics.

The principal power limitation on such coils is the thermal softening point of the adhesives that bonds the wire to the bobbin, or the bobbin to the spider and coil.

You can then follow the links to the most complete data sheets on the Web, with information such as dielectric constant, Poisson's ratio, glass transition temperature, dissipation factor, and Vicat softening point.

At a temperature of just about 100 C, the softening point of styrene, the polymer "unzips" that is "de-polymerizes" to yield styrene monomer, which has a characteristic "aromatic hydrocarbon" odor.

Zinc oxide, bismuth trioxide, and copper(II) oxide can be added for influencing the thermal expansion; unlike the alkali oxides, these lower the softening point without increasing of thermal expansion.

One of the unique attributes of LaRC-SI is that when it is exposed to temperatures above its softening point of 250 C, it cannot be redissolved, yet it maintains its amorphous character and melt processability.

The wafers are placed between the chuck and the top tool used as bond electrode at temperatures between 200 and 500 C (compare to image "scheme of anodic bonding procedure") but below the softening point of glass (glass transition temperature).

Typically used for tarring roads and roofs, the material must be semi-solid in normal weather under the hot sun, so tar, which is a mixture of a large number of different complex hydrocarbons and doesn't have a single melting point, must have a high "softening point," the temperature at which the material becomes too soft to do its job.
