Sol-gel technique is particularly interesting due to possibility of the organic-inorganic composite material production, which porous structure ensures high solid<->liquid and solid<->gas contact surface. 

The composition of the conversion gas corresponds to the sum of the inorganic and organic gaseous pyrolysis products illustrated in Figure 54... 

The TSCA Inventory provides an overall picmre of the organic, inorganic, polymers, and UVCB (chemical substances of Unknown, or Variable Composition, Complex Reaction Products, and Biological Materials) chemicals produced, processed, or imported for commercial purposes in the United States. The Inventory is not a list of chemicals based on toxic or hazardous characteristics, since toxicity/hazard is not a criterion for inclusion in the list. The Inventory includes chemical substances of any commercial use in the United States since 1979 under the Environmental Protection Act, and is prepared by the US-EPA. The current TSCA Inventory contains approximately 81,600 chemicals. Currently, OPPT is focusing on a subset of approximately 3,000 HPV... 

Basically a plastic composite is the assembly of two or more materials made to behave as a single product. Examples include vinyl-coated fabric used in air mattresses or laminated metal bonded together with a plastic adhesive used in helicopter blades. The RP type of composite combines a plastic with a reinforcing agent that can be fibrous, powdered, spherical, crystalline, or whisker, made of organic, inorganic, metallic, or ceramic material. To be structurally effective, there must be a strong adhesive bond between the resin and reinforcement. 

In the last two decades, RH and the products of its thermal degradation are often used as fillers in paper, paint [5], polymers [42, 43], polymeric composites [44 7], mbber [48-50], cement [51, 52], adhesives, and fertilizers [5]. By the addition of fillers, the mechanical, thermal, chemical, and other properties of the material are improved. Controlled burning of RH in air or inert atmosphere yields two grades of fillers, namely white rice husk ash (WRHA) and black rice husk ash (BRHA). Both these RHA have been used as fillers in polyethylene [53-55], polypropylene [56-61], polystyrene [62, 63], etc. [64, 65]. Tremendous opportunities exist in more exhaustive research on the RHA-polymer composites, which can lead to the futuristic organic-inorganic hybrid materials with specific properties. In this respect, the aim of the present work is to describe the possibility for utilization of RRHs and the products of its thermal degradation as fillers in different polymer plastic composites.
