Question

What is the Adhesive (Thermoplastic) - What is a thermoplastic adhesive??

Accepted Answer

A type of adhesive that is not irreversibly changed by the curing process  Thermoplastic polymers become pliable above a certain temperature  which allows them to be moulded into the required form before they are hardened into a solid via a curing process  they are usually cured using heat  with or without pressure   While thermosetting polymers undergo a chemical reaction during curing  thermoplastic polymers do not  which means that they can be recycled by re-melting and re-shaping the material  They tend to have a high molecular weight  which means that the polymer chains  which are associated through intermolecular forces  weaken extremely quickly at higher temperatures  allowing the polymer to become pliable enough to be moulded into the required shape  via injection moulding  compression moulding  calendaring  extrusion etc   Compared to thermosetting adhesives  thermoplastic adhesives tend to have a superior finish  and offer a wider range of surface finishes   offer better impact resistance  can be recycled  or simply remoulded if required   and use eco-friendly manufacturing processes  although they are more expensive and will melt if they are exposed to higher temperatures
