We use the Dunlop process. Delayed action is the keep to the success of this process. This means that gelling agents are used such as sodium silicofluoride to prevent from quick gelation. While the product is being stripped (removed) off the mould it should contain a high quantum of water. The presence of water prevents the mattress being torn further, enhances the stripping process. The gelling starts to occur when the PH scale indicates between 8-9, and finally get gelled between 7-8. This is the PH equilibrium for gelation. |
