Plastics exam 2 Questions with Answers (100% Correct
Answers)
additives Answer: a chemical added to something in small quantities,
typically to improve or preserve it.
Anti-oxidants Answer: chemicals added to products to prevent
oxidation
antistatic agents Answer: reduce a material's likelihood of maintaining
static electricity
Colorants Answer: dyes, pigments, and optical brighteners used to
apply color to fibers, yarns, fabrics, and garments
coupling agents Answer: is a chemical which improves the adhesion
between two phases in a composite material. The term 'composite' is
used here to denote a material which has two or more distinct
constituents, not chemically bound to each other.
curing agents Answer: can be defined as a substance able to participate
in the chemical reaction between the oligomer, pre-polymer and

polymer, to achieve the polymerization process and provide the final
film.
flame retardants Answer: prevent material from sustaining a flame
Foaming/Blowing Agents Answer: The blowing agent is used to create
a cellular structure from liquid plastic resin, and in the case of foam
used for insulation
Heat Stabilizers Answer: These additives increase the ability of the
material to withstand the negative effects of heat exposure. They are
used to increase the overall service temperature of the material.
Impact Modifiers Answer: Additive used to enhance the material's
ability to withstand the force of impact.
Lubricants Answer: substances that are applied to surfaces to reduce
the friction between the surfaces
nucleating agents Answer: has a surface charge that is opposite to the
partial charge of the chemical moiety of the polymer. It accelerates its
rate of crystallization, and a melting point is greater than the melting
point of the melt processible polymer.
