Resin is usually refers to the scope of heated after soften or melt, softened
under the action of external force has a tendency to flow, when the temperature
is solid, semi-solid, and sometimes can be a liquid organic polymer. Broadly
speaking, can any polymer compounds as raw materials for the plastic products
processing is called resin. Resin is the main raw material, manufacturing
plastic is used for making coating (coating is the main film-forming material,
such as: alkyd resin, acrylic resin, synthetic fatty acid resin, the resin in
the Yangtze river delta and the pearl river delta, is also due to relatively
strong area, such as chemical, changxing new pace resin, three full resin, DSM
first of resin, etc.), adhesives, insulation materials, the combination of the
diamond tool agent (drum various resins, resin polish pad, resin grinding wheel), such as
synthetic resin in industrial production, are widely used in the separation and
purification of the impurities in the liquid, with macroporous resin adsorption,
ion exchange resin, as well as some special resin.
Relative molecular weight of uncertain but usually is
higher, in the normal temperature is solid, solid, solid, sometimes also can be
a liquid organic matter. Soften or melt temperature range, has a tendency to
flow under the external force, fracture often assumes the shells. Broadly refers
to the polymer is used as the plastic base material or prepolymer. Generally
does not dissolve in water, soluble in organic solvents. According to the source
can be divided into natural resin and synthetic resin; According to the
different processing behavior has the characteristics of thermoplastic resin and
thermosetting resin.
