Typlax Uses Tires

To Make BlendsCHESHIRE, Conn. - Typlax Products Inc., a subsidiary of RW Technology Inc., is using rubber powder from discarded tires to produce impact resistant plastic blends for making a variety of end-use products.

The company's plastics and rubber blends, which can contain up to 80 percent rubber, can be made into footwear, flooring, pipe, industrial handling containers, automotive parts and highway safety cones, a company spokesman said.

Greg Koski, vice president for Typlax, said that discarded tires in the U.S. currently amount to 2 billion a year. Each year 200 to 240 million more tires are added to this total, he noted.

The recycling of the tires to enhance the toughness of plastics does not produce any by-products harmful to the environment, the spokesman said.

Hoechst Celanese

Offers PEI Fibers

CHARLOTTE, N.C. - The Specialty Fiber Products unit of Hoechst Celanese Corp.'s Industrial Fibers group has announced the initial commercial availability of developmental quantities of multifilament polyetherimide, or PEI fibers.

The fibers are being produced from General Electric Co.'s Ultem resin. PEI fibers are intended for use as a matrix material for reinforced-plast ic aerospace composites, as well as for general industrial uses requiring resistance to high temperature and fire.

Yarns of PEI fibers comingled with glass and other reinforcing fibers will be offered in the near future, a Hoechst Celanese spokesman said. A.R. Van Landingham, the market development manager for Specialty Fiber Products said, PEI products will greatly enhanceindustry's efforts to develop thermoplastic composite parts, particularly in complex shapes, in support of improved material processing. Other industrial uses are anticipated.

Mitsui Toatsu Gets

Catalyst License

TOKYO - Mitsui Petrochemical Industries Ltd. (MPC) has recently granted Mitsui Toatsu Chemicals Inc. a license for high-yield high-stereospecifi city (HY-HS) catalyst technology for polypropylene manufacture.

The technology was jointly developed by MPC and U.S.-based Himont Inc.

The HY-HS catalyst technology cuts the cost of polypropylene production and improves its quality.

To date, MPC and Himont have licensed the technology to numerous polypropylene manufacturers, with the total licensed annual production capacity having reached more than 7 million tons.
