Phthalate-free hardening powder GreenLine

Making work safe in the orthopaedic workshop

The phthalate-free hardening powder marks the beginning of a new generation of materials offering an ideal combination of functionality and occupational health and safety. The hardening powder is less harmful to health than comparable products and thereby improves occupational health and safety in the orthopaedic workshop.

By replacing dicyclohexyl phthalate, which is a substance of very high concern, this hardening powder is far less hazardous to health, and the risk associated with its processing is reduced.

Information on the areas of application and properties of lamination resins

  • Duroplastics


  • What is meant by phthalate-free?

    This means the production of the hardening powder without the adding of dicyclohexyl phthalate. By replacing dicyclohexyl phthalate, which is a substance of very high concern, this hardening powder is far less hazardous to health, and the risk associated with its processing is reduced.

  • What is the difference of phthalate-free and CMR-free?

    CMR substances are substances classified as carcinogenic, mutagenic or toxic to reproduction. The previous phthalate of our well-proven hardening powder 617P37 was CMR. And now there are no CMR substances in it and so CMR free is valid for our new hardening powder 617PG37.

  • What is the difference between 617PG37 and 617P37?

    The difference is just the replacing of dicyclohexyl phthalate in 617PG37. Processing and the final product is the same.

  • Is the mixing ratio of 617PG37 the same as for 617P37?

    The mixing ration for 617PG37 is similar for 617P37. The mixing ration is for all Orthocryl resins to add max. 3% 617PG37 hardening powder and for Orthovinyl to add max. 2% 617PG37 hardening powder.

  • Does the new 617PG37 replace the 617P37?

    Both products will be available in the portfolio until further notice. Mid-term replacement/phase out 617P37 by 617PG37 is planned. However, 617P37 will stay in the global portfolio for the time being.

  • Do I have to order the measuring spoon separately?

    No, the measuring spoon is included in every sales package.

  • What are the differences in curing time 617PG37 vs. 617P37?

    No differences in curing time between 617PG37 and 617P37.

  • What are the differences in viscosity behavior 617PG37 vs. 617P37?

    No differences in viscosity behavior between 617PG37 and 617P37.

  • Which hazard symbol could be deleted from 617PG37?

    The hazard symbol carcinogenic could be deleted because the CMR substance could be removed. Now only three hazard symbols are relevant.

  • Why do 617P37 and 617PG37 have the same dangerous goods number (UN 3106, Class 5.2), even though a substance of very high concern has been eliminated from 617PG37?

    Dangerous goods regulations refer to the hazards during transport (in public traffic areas). In this case, other standards may be important than in the handling of hazardous substances, which in turn is specified in the Dangerous Substances Regulations.

    When transporting 617P37 and 617PG37, the "most dangerous" thing is the self-ignition or, in this case, the self-accelerating decomposition of the peroxide in the two substances, which can be caused by excessively high temperatures, e.g. on the truck, in the case of some peroxides. For the transport it is therefore primarily irrelevant whether SVHC substances are contained or not. Both have peroxides as a component, therefore UN 3106 (organic peroxide type D) for both products.

    From the point of view of the law on hazardous substances, there are significant differences between the two. These are expressed, among other things, in the safety data sheet by the hazard statements. The hazardous statements come from the hazardous substance's legislation, the handling / working with the hazardous substance. Here, the heating and possibly heating up to the fire hazard is also important (e.g. during storage) and is therefore also addressed in the safety data sheet, but the carcinogenic or reproductive toxic property is "more important" when handling the substance according to the hazardous substances law and are there also changes in the H-phrases, if one compares 617P37 with 617PG37.

    Against this background, nothing can be changed in the UN No. Moreover, this is determined according to a classification procedure. This does not allow any room for classification.
