Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
A non-plastic material used in clay bodies to attenuate drying shrinkage. Finely milled quartz is a common filler. Filter press A piece of equipment used to separate liquid and solid from an aqueous suspension: a slurry, or slip, is pumped into the filter press and is dewatered via semi-permeable cloths whilst under fluid pressure.
Once conditioned, the clay will remain pliable until the particles eventually re-adhere. [8] Oven-hardenable PVC plastisol, "liquid polymer clay," is a complement to polymer clay that can be used as an adhesive to combine pieces, or to create various effects. Pigments, chalk pastel, and regular polymer clay can be added to make colored liquid clay.

Glass-ceramics have the fabrication ...

They are also used as fillers for orthopedic plastic screws to aid in reducing inflammation and increase the absorption of these plastic materials. Work is being done to make strong, fully dense nanocrystalline hydroxyapatite ceramic materials for orthopedic weight bearing devices, replacing foreign metal and plastic orthopedic materials with a ...
