2. Polyester resin - Wikipedia

   en.wikipedia.org/wiki/Polyester_resin

   Polyester resins are synthetic resins formed by the reaction of dibasic organic acids and polyhydric alcohols. Maleic anhydride is a commonly used raw material with diacid functionality in unsaturated polyester resins. [1] Unsaturated polyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers.

3. tert-Butyl peroxybenzoate - Wikipedia

   en.wikipedia.org/wiki/Tert-Butyl_peroxybenzoate

   Primarily, TBPB is used as a radical initiator, either in the polymerization of e.g. ethylene (to LDPE), vinyl chloride, styrene or acrylic esters or as so-called unsaturated polyester resins (UP resins). [2] The quantity used for the curing of UP resins is about 1-2%. [2]

4. Maleic anhydride - Wikipedia

   en.wikipedia.org/wiki/Maleic_anhydride

   Around 50% of world maleic anhydride output is used in the manufacture of unsaturated polyester resins (UPR). Chopped glass fibers are added to UPR to produce fiberglass reinforced plastics that are used in a wide range of applications such as pleasure boats , bathroom fixtures, automobiles, tanks and pipes.

5. Polybutylene succinate - Wikipedia

   en.wikipedia.org/wiki/Polybutylene_succinate

   Polybutylene succinate (PBS) (sometimes written polytetramethylene succinate) is a thermoplastic polymer resin of the polyester family. PBS is a biodegradable aliphatic polyester with properties that are comparable to polypropylene. It may also be referred to by the brand names GsPLA or BioPBS (Mitsubishi Chemical). [1]

6. Methyl ethyl ketone peroxide - Wikipedia

   en.wikipedia.org/wiki/Methyl_ethyl_ketone_peroxide

   Solutions of 30 to 40% MEKP are used in industry and by hobbyists as catalyst to initiate the crosslinking of unsaturated polyester resins used in fiberglass, and casting. For this application, MEKP often is dissolved in a phlegmatizer such as dimethyl phthalate , cyclohexane peroxide , [ clarification needed ] or diallyl phthalate [ de ] to ...

7. Isophthalic acid - Wikipedia

   en.wikipedia.org/wiki/Isophthalic_acid

   Isophthalic acid is an organic compound with the formula C 6 H 4 (CO 2 H) 2.This colorless solid is an isomer of phthalic acid and terephthalic acid.The main industrial uses of purified isophthalic acid (PIA) are for the production of polyethylene terephthalate (PET) resin and for the production of unsaturated polyester resin (UPR) and other types of coating resins.

8. Thermoset polymer matrix - Wikipedia

   en.wikipedia.org/wiki/Thermoset_polymer_matrix

   Unsaturated polyester resins are an extremely versatile, [12] [13] and fairly inexpensive class of thermosetting polymer formed by the polycondensation of glycol mixtures often containing propylene glycol, with a dibasic acid and anhydrides usually maleic anhydride to provide backbone unsaturation needed for crosslinking, and phthalic anhydride ...

9. Propylene glycol - Wikipedia

   en.wikipedia.org/wiki/Propylene_glycol

   Forty-five percent of propylene glycol produced is used as a chemical feedstock for the production of unsaturated polyester resins. In this regard, propylene glycol reacts with a mixture of unsaturated maleic anhydride and isophthalic acid to give a copolymer. This partially unsaturated polymer undergoes further crosslinking to yield thermoset ...
