AMERIPOL® RUBBER PUTS MORE MILEAGE IN
THE
BOX
One of the country's
largest producers of tread rubber for tire recapping now uses a tailor-made Ameripol MICRO-BLACK* Masterbatch for a large part of its production. As a result, Long Mile Rubber Corporation of Dallas, Texas, has substantially improved tread wear, as well as product appearance and physical bond. In the bargain, processing time was cut 50% since Ameripol MICRO-BLACK is delivered "pre-mixed". This saves time-consuming operations for the fabricator.
UNIQUE VALUES WITH AMERIPOL MICRO-BLACK Carbon black is rubber's best reinforcing agent. . . and the better the dispersion, the more carbon black contributes to strength and wear resistance. MICRO-BLACK's fine dispersion of carbon black gives the ultimate
NEW SYNTHETIC OUTPERFORMS NATURAL RUBBER IN HEAVY-DUTY APPLICATIONS Ameripol CB* is a new cis-polybutadiene rubber which is superior to natural rubber in abrasion resistance, resilience, and low-temperature flexibility. In truck tire use, it has delivered up to double the life of standard treads. An example of exhaustive road tests is shown below. On a single tire, half the tread was made of Ameripol CB, the other half of standard compounds. The Ameripol CB tread shows 9 times the tread Ameripol CB is unique among polydepth in the center. butadiene rubbers. Its high cis-content (98%) and processing treatment enable it alone to serve as a complete replacement for natural rubber in applications such as truck tire treads, conveyor belt covers, power transmission belts, tank treads, chute liners, and similar products where maximum re sistance to abrasion and flex cracking are mandatory. Yet, whether used as a 100% replacement, or in blends with natural and/or styrene-butadiene rubber, it can be mixed and processed on existing equipment.

in quality and performance. MICRO-BLACK is packaged for fast, easy handling, elimi nates cost of in-plant storage of carbon black. MICRO-BLACK has latex and carbon already precisely mixed. This eliminates time-con suming weighing and milling operations, shortens mixing time. Clean-up time between runs is also reduced. • Every rubber-using product ideally requires a different balance of properties. That's why it makes sense to do business with Goodrich-Gulf, producer of the broadest range of synthetic rubber polymers, and technical leader of the industry. For
