Description
Specifications
  • The kit includes 100g smart putty, 500g polymorph and 500g bag of hydrogel
  • Polymorph is one of a new generation of commercial polymers set to have a major impact on model making and prototyping
  • This polymer has all the characteristics of a tough ';engineering' material yet it softens and becomes easily mouldable at just 62¼C
  • It can be heated with just hot water or a hairdryer and can then be moulded by hand to create prototypes and solve manufacturing problems currently outside the capacity of other materials
  • Polymorph can be reused simply by reheating, the material can also be coloured when soft by adding a small amount of food dye
  • Smart putty has been available for a long time as an amusement, but this viscoelastic polymer has serious engineering applications
  • Soft, stretchy and bendy when moved slowly, solid when trying to move quickly or impacted
  • It has the remarkable property that it usually behaves as a soft mouldable plastic (like chewing gum), but instantly becomes a rubber if impacted and bounces like a ball
  • It can also float in a liquid and will form a puddle given enough time
  • It is a great demonstration of an unusual polymer, a useful adhesive and can used in many creative and fun activities
  • Hydrogel: This completely non‐toxic powder absorbs up to 500 times its own weight in water and is the 'secret' ingredient used in applications ranging from babies nappies to perpetual growing plants
  • When exposed to water, the powder transforms into a gel which holds the water for an extended period
  • Place a small pile of Hydrogel in the centre of a Petri‐dish and add drops of water from a syringe or pipette
  • The Hydrogel will swell until it can absorb no more water
  • This can be a simple quantitative experiment by weighing before and after water absorption
  • This grade of Hydrogel can also be used in the lab or prep‐room to assist the growth of small plants, especially over weekends
  • The amount added to the soil or growing medium needs to be determined by trial and error
