WitrynaThermosetting polymer, often known as a thermoset or thermosetting plastic, is a polymer made up of highly branched molecules or a cross-linked structure. The thermosetting polymers harden throughout the moulding process and cannot be re-softened with heat. Bakelite and urea-formaldehyde resins are examples of … WitrynaThermoset polymers have crosslinks tying their chains together. These crosslinks form between the chains, turning them into one big molecule. Think about that the next time you’re holding a bowling ball. Crosslinks provide a robust chain structure that allows elastomeric materials such as liquid silicone rubber to be used well above their Tg.

WitrynaDue to its high level of hardness and rigidity, the new silicone grade can be used as an alternative to thermoplastics or thermosets.
