Material Safety Data Sheet Polyethylene NanospheresClear polyethylene Nanospheres are supplied in dry powder form. Polyethylene beads can be used to produce porous ceramics by burning out the polymer. Highly hydrophobic nanopowder is excellent as a water repellant additive Tru Particle density: 0.92g/ml-0.99g/ml Particles in Size Range: > 95%Spherical Particles: >90% Auto-Ignition Temperature: 330-410dCIn-stock orders ship in 1 business day.
