Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not … Visa mer Curing a thermosetting resin transforms it into a plastic, or elastomer (rubber) by crosslinking or chain extension through the formation of covalent bonds between individual chains of the polymer. Crosslink density varies … Visa mer Thermosetting plastics are generally stronger than thermoplastic materials due to the three-dimensional network of bonds (crosslinking), and are also better suited to high- Visa mer • Polyester resin fiberglass systems: sheet molding compounds and bulk molding compounds; filament winding; wet lay-up lamination; repair compounds and protective coatings.

Webb2 okt. 2024 · Many thermoplastic polymers such as polyethylene can have very high elongations at break (upwards of 400-800%). These polymers are termed “soft and tough” since the Young’s modulus is typically low, but after yielding, they can exhibit a large amount of continued elongation.
