In harsh industrial environments, cable failure isn't just inconvenient — it can lead to costly downtime, safety risks, and frequent replacements. That's why thermoset jacketing has remained a core part of Amphenol TPC's cable design philosophy for decades. So, what exactly are thermosets? You may be familiar with everyday thermoplastics – things like PVC – that soften and melt when exposed to heat. Thermosets like vulcanized rubber and epoxy resins are the exact opposite in terms of what happens in the presence of heat. After they’re initially cured, they cannot be remelted. Able to withstand heat, abrasion, impact, oils, and demanding operating conditions, thermoset materials deliver the rugged durability industrial operations depend on.
