Nano Particle Reinforced Polymer T echnology
Nano Reinforced Compounds: Defined Addition of nano particle to polymer matrix Nano particle: one dimension <nanometer High Aspect (length/thickness) Ratio Confidential
Aspect Ratio Length : Thickness ratio Effectiveness of reinforcement in polymer matrix How much stress transferred to fibers or platelets aspect ratio reinforcement = increase in strength Nano Clay < 1nm thick Aspect Ratio: 300:1 – 1500:1 Confidential
Why Nano Compounds? Low Filler Loadings Required Improves rigidity (‘catheter pushability ’) Preserves elongation of polymer Preserves surface finish Light weight blend Unique particle/shape Improves barrier properties Non-organic = improves thermo-mechanicals Char forming = flame retardance Nucleating = improves processing time Confidential
Nano Clay Clay Platelets Held by Electrostatic Forces Negative Surface Charge Nano Clay is Difficult to Mix in Polymers Confidential
T win Screw Compounding Dry form: nano clay clusters or aggregates Exfoliation exposes surface area of particles Twin screw compounding: homogenous distribution Confidential
