  • Patent number: 8137592
    Abstract: A method of incorporating an additive into a polymer composition includes the step of melt blending a polymer with a dispersion comprising a liquid carrier, an unmodified clay, and an additive. Using the dispersion rather than a polymer-based additive masterbatch saves energy. Like a polymer-based masterbatch, the dispersion provides the additive in a diluted form and therefore preserves the masterbatch's advantages of providing more uniform distribution additive in the plastic and avoiding direct handling of additives in the final compounding step. The dispersion is also described.

  • Patent number: 8097186
    Abstract: A method is disclosed for producing a non-linear powder having microvaristor particles which have a non-linear current-voltage characteristic. The production steps includes mixing non-metallic particles with the microvaristor particles, thermally treating the non-metallic particles for decomposing them into electrically conductive particles and fusing the electrically conductive particles onto the microvaristor particles. Embodiments, among other things, relate to: breaking up agglomerates of the non-metallic particles during mixing; keeping the decomposition temperature below a sintering or calcination temperature of the microvaristor particles; and choosing micron-sized or nano-sized non-conductive particles for microvaristor decoration. The production method produces varistor powder with improved reproducibility of the non-linear electric current-voltage characterstic and with reduced switching fields (Es).
