Acrylic resins are thermoplastics or
thermosetting plastics, derived from acrylic acids.
Examples of
thermosetting plastics are polyester resins used in glass reinforced plastics work, and melamine formaldehyde used in the manufacturing of Formica for kitchen work surfaces.
By modifying sugar acids, it is also possible to produce compounds that may replace oil-based aromatic acids in the manufacture of
thermosetting plastics and textiles.
Applied to a clean, warm mold, RR-380WB1 forms a thin, highly durable film with good adhesion to the mold, capable of releasing a broad cross-section of elastomers and
thermosetting plastics. Laboratory and field trials are said to indicate that RR-380WB1 gives an increased number of cycles between applications, enhanced part appearance and ease of release, along with reduced defects and allowing longer times between mold cleaning, according to the company.
He has also been involved in work on the processing and end product properties of
thermosetting plastics, and in the use of flow simulation software for both thermoplastics and thermosets.
Thermosetting plastics include phenolic, epoxy, alkyd polyester, polyurethane, urea-formaldehyde and unsaturated polyester resins.
The host polymers include both thennoplastic and
thermosetting plastics; the structures are of various shapes and dimensions, and the perfonnance enhancements range from mechanical to thermal, electrical and photonic.
When applied to a clean, warm mold, RR-280 WB will give a thin, highly durable, heat stable release film capable of releasing a wide cross-section of elastomers and
thermosetting plastics, according to the manufacturer.
Q-Cel hollow microspheres are fine, inorganic spherical particles developed as low-density fillers/extenders for
thermosetting plastics. Can be used in polyurethanes, plastisols, polyester casting, spray-up, SMC, BMC and syntactic foams.
