Plastics additives mold release agents

Because plastics are almost invariably modified with one or more additives, there are three components of chemical analysis the high molecular weight portion, ie, the polymer the additives, ie, plasticizer and mold-release agent and the residuals remaining from the polymerization process. The high... 

This moldable material primarily consists of TS polyester resin, glass fiber reinforcement, and filler. Additional ingredients, such as low-profile additives, cure initiators, thickeners, and mold-release agents are used to enhance the performance or processing of the material. As with any material, such as metallics and plastics, SMC can be formulated in-house or by compounders to meet performance requirements of a particular application such as tensile properties or Class A surface finish. Varying the type and percentage of the composition will result in variations in mechanical properties and processability.

The topics to be covered in some detaU in this chapter are antistats, blowing agents, catalysts, fire retardants, mold-release agents, nucleating agents, reinforcements, stabilizers, and surfactants. These topics are presently in alphabetical order as a matter of convenience. The reader should be aware that there are a number of additives used in plastic foams that serve dual functions. These will be noted in the following text.

These properties allow them to be employed in a myriad of applications in addition to surface coatings, including plastic moldings (16). electrical insulators (17). cleaning substances, shoe-, furniture-, automotive, and floor waxes (18). in virological practice (19). cloth coatings, and mold release agents, biomedical applications, and hydraulic fluids and lubricants (20).

Mold release agents are often used to facilitate the removal of plastic parts from molds by acting to decrease the adhesion between the plastic and the mold. Mold release agents may be sprayed or otherwise applied to the mold surfaces, as an alternative to, or in combination with, compounding the additives into the resin. These agents may be liquids that provide lubrication, such as those mentioned previously, or may be fine solids such as dusting powder.
