PU Casting Resins - Safe, Efficient, and Universally Applicable 

The PUR casting resins from HellermannTyton combine high insulation security with easy processing and offer both technical and economic advantages. Particularly noteworthy is their low exothermic reaction temperature, which allows for the casting of larger amounts of resin without excessive heat development or material stresses.

The PUR 33 was specially developed for universal application on plastic cables of any kind. It is hydrophobic and hydrolysis-resistant and can even be cast under water. The resin hardens bubble-free to form a homogeneous mass and is operationally ready after gelling - ideal for quick and permanent cable connections in demanding environments.

Intelligent packaging for safe working
Casting resins are delivered in a transparent dual-chamber bag that allows for safe, contactless mixing. With PUR 33, a patented color change from blue to green indicates successful mixing. To protect against environmental moisture, delivery is in a light-tight aluminum packaging with printed processing instructions - for maximum safety and clarity on the construction site.

Main features: 

• PUR casting resin with low reaction temperature 
• Underwater casting possible - bubble-free hardening 
• Hydrophobic and hydrolysis-resistant 
• Color change for mixing control (blue → green) 
• Dual-chamber bag with light-tight outer packaging 
• Quick operational readiness after gelling 

Typical applications: 

• Connections and branches on plastic cables 
• Outdoor and subfloor installations 
• Moist and wet environments

Conclusion: With PUR casting resins, you benefit from a safe, easy-to-process solution that provides reliable electrical insulation even under the most challenging conditions.
