Giving a Second Life to Reactive Polyurethane Flushing Waste

AI Quick Summary

During the production of polyurethane adhesives and sealants a certain amount of waste is generated. This waste is flushing material from colour or product changes at the production or packaging lines. The waste is uncured of a pasty consistency and will cure with humidity to an elastic polymer.The material can be grouped in two categories: Waste from sealant production:Cures with humidityFilled paste of “low” viscosity (Nutella like)Colours manly white and grey but currently not separatedLower mechanical propertiesShore A hardness in the range of approx. 20-40 after curing Waste from adhesive production:Cures with humidityFilled paste of high viscosityHighly filled with carbon black, therefore only in black colourHigher mechanical propertiesShore A hardness in the range of approx. 40-60 after curing The production waste is collected in 200L steel drums with plastic inliner.As the waste is currently incinerated, we are looking for a more ecological way of disposal or for an application where the material can be reused.Implementation Partner: SIKA Technology AGSika is a specialty chemicals company with a leading position in the development and production of systems and products for bonding, sealing, damping, reinforcing, and protecting in the building sector and motor vehicle industry.Sika has subsidiaries in 101 countries around the world and manufactures in over 300 factories.

Challenge Description

During the production of polyurethane adhesives and sealants a certain amount of waste is generated. This waste is flushing material from colour or product changes at the production or packaging lines. The waste is uncured of a pasty consistency and will cure with humidity to an elastic polymer.

The material can be grouped in two categories:

Waste from sealant production:

• Cures with humidity
• Filled paste of “low” viscosity (Nutella like)
• Colours manly white and grey but currently not separated
• Lower mechanical properties
• Shore A hardness in the range of approx. 20-40 after curing

Waste from adhesive production:

• Cures with humidity
• Filled paste of high viscosity
• Highly filled with carbon black, therefore only in black colour
• Higher mechanical properties
• Shore A hardness in the range of approx. 40-60 after curing

The production waste is collected in 200L steel drums with plastic inliner.

As the waste is currently incinerated, we are looking for a more ecological way of disposal or for an application where the material can be reused.
