Huntsman Turns up Heat with New PU Tooling Technology

VITROX® EST system: fast-cure PU to take high temperature tooling to a new dimension



Everberg, BELGIUM – Huntsman has made a major tooling technology breakthrough with the launch of a new polyurethane resin system that cures extremely quickly and allows the production of high heat stable modeling, tooling and rapid prototyping boards.

The availability for the first time of an effective, high temperature stable polyurethane will open up a world of new opportunities in a wide range of sectors including aerospace, automotive, marine and shipbuilding.

With a glass transition temperature (Tg) of 200oC and higher, the new generation VITROX® EST system offers product designers, tooling manufacturers and mold-makers a viable polyurethane alternative to other thermoset-based tooling products – with a number of additional advantages.

The fast cure features of Huntsman’s VITROX® EST system make it possible to significantly reduce demolding and manufacturing cycle times. This can help manufacturers increase productivity, reduce energy costs and cut carbon emissions. The VITROX® EST system can also be precisely formulated to suit specific requirements – offering added flexibility and broadening scope for innovation. 

VITROX® EST system’s high Tg properties mean a constant coefficient of thermal expansion (CTE) from room temperature to 200oC is achievable. This enables the creation of products and tooling boards with improved long-term stability when exposed to high temperatures. Products and tooling boards made with the VITROX® EST system also demonstrate better impact resistance and a good machinability. 

Processing benefits include a long, tunable pot life (5-20 minutes) and a low viscosity. Furthermore, the system is processable on low pressure casting machines.

Wim Gilis, Technical Manager at Huntsman Polyurethanes, said: “Until now, polyurethanes couldn’t match the high-temperature performance offered by other thermosets, but the development of our VITROX® EST system offers forward-looking tooling manufacturers an attractive alternative with all the benefits of polyurethanes chemistry. We constantly strive to develop advanced tooling technologies with additional properties and features to help our customers innovate, boost productivity, reduce costs and gain competitive advantage. The VITROX® EST system is an exciting breakthrough, one we believe will take tooling technology into a new dimension.”

Interested parties can find out more about Huntsman’s VITROX® EST system during UTECH Europe 2015, which takes place in Maastricht, The Netherlands from 14 April. During the UTECH Europe conference, Wim Gilis will give a presentation on the system entitled: ‘High temperature stable VITROX® EST resin system for advanced tooling boards’. The presentation will be delivered during the innovation session in the Florin Room at 14:15 on Tuesday 14 April. For more information please email: or go to:
