Re: Source of Peptizer



Kirsten -

Here is some information from Goodyear <http://www.goodyear.com>
regarding what is in tires:

TIRE INGREDIENTS 

1.Here are the basic ingredients of tires: 

Fabric: steel, nylon, aramid fiber, rayon, fiberglass, or polyester
(usually a combination, e.g., polyester fabric in the body plies and
steel fabric in the belts and beads of most radial passenger tires) 
              
Rubber: natural and synthetic (hundreds of polymer types) 
              
Other: 
    Reinforcing chemicals -- carbon black, silica, resins 
    Anti-degradants -- antioxidants/ozonants paraffin waxes 
    Adhesion promoters -- cobalt salts, brass on wire, resins on fabrics 
    Curatives -- cure accelerators, activators, sulfur 
    Processing aids -- oils, tackifiers, peptizers, softeners 
    
2.A P195/75R14 all-season passenger tire, the most popular size, weighs
about 21 pounds and has approximately: 
    5 lbs. of 30 different types of synthetic rubber 
    4 lbs. of 8 types of natural rubber 
    5 lbs. of 8 types of carbon black 
    1 lbs. of steel cord for belts 
    1 lb. of polyester and nylon 
     lb. of steel bead wire 
	3 lbs. of 40 different kinds of chemicals, waxes, oils, pigments, etc. 

3. Typical percentages of the rubber mix in various types of tires: 

					Synthetic Rubber 	Natural Rubber 

Passenger Tire 				55% 			45% 
Light Truck Tire 			50 				50 
Race Tire 					65 				35 
Off-highway Tire 			20 				80 (giant/earthmover)
