DSM Engineering Plastics of Evansville, Ind., introduced new grades of wear-resistant, low-friction, aramid fiber-reinforced ny-lon resins for load-bearing applications such as gears, bushings and seals. Plaslube nylon 612 has good dimensional stability and contains lubricant. Stanyl nylon 46 is a high-temperature product with added lubricant. Each is available with aramid fiber loadings of 5-15 percent.
Ten percent-aramid grades cost about $6 per pound.

Colorite Polymers Co. introduced a flexible PVC compound designed to bond well with CPVC resin in applications such as coextruded window profiles.
Unichem 95-950P can be processed on standard coextrusion systems, claimed Colorite. As an alternative to thermoplastic rubbers, it offers low temperature and weather resistance.
Colorite also developed a noncadmium, flexible PVC compound for polyester film overlay applications in automotive body side moldings.
Unichem 9003C is fungus resistant and has excellent clarity, claimed the Ridgefield, N.J., compounder. The material has high clarity and outstanding processability, and has been approved by Ford Motor Co., General Motors Corp., and Chrysler Corp., according to Colorite.

PQ Corp. has a new anti-block and a heat stabilizer for PVC compounds. Both are based on aluminosilicate chemistry, the Valley Forge, Pa., firm said.
AB10N, the anti-block, can absorb odors and metal ion contaminants in PVC and other films. The heat stabilizer, HS10N, neutralizes acid formation and reduces development of white film in PVC siding caused by ultraviolet degradation, PQ claimed. HS10N also cuts down on plastic buildup on dies and acts as a synergist with other stabilizers in rigid and flexible PVC.

Norton Performance Plastics Corp. offers a cost-effective, high-performance perfluoro-alkoxy film for composites, microwave laminates, linings and other applications.
Korton MFA has a continuous use temperature of 230§ C, the Wayne, N.J., firm said. It also has good release properties, weldability and chemical resistance, and low haze. Norton makes high-clarity Korton MFA in a Class 100,000 clean room in widths to 64 inches.

SolarActive of Van Nuys, Calif., broadened its line of photochromic dye products that change from colorless to brilliant colors when exposed to ultraviolet light.
The firm, a subsidiary of Hatteras Enterprises Inc., now offers coatings, sprays and dips and boosted to 18 the number of colors. It earlier this year introduced photochromic masterbatch compounds for injection and blow molding and silk screen inks.

Cincinnati-based Canusa-Emi, a subsidiary of Shaw Resource Services Inc., uses Temp-Alarm temperature signaling paint in its cross-linkable tubing for TV cable splicing. It uses the Temp-Alarm 13A formulation, which changes from blue to black at 300§ F. Tempil division of Air Liquide America Corp. of South Plainfield, N.J., supplies the paint.

Eastman Chemical Co. offers a ultraviolet-absorbing version of its Spectar copolyester resin for coextruding onto sheet made of regular Spectar PETG high-clarity resin.
The Kingsport, Tenn., firm said the new material, when extruded as a capstock, will allow retailers to display their message outdoors. Spectar-based sheet has been used in indoor signs and point-of-purchase displays because of easy thermoforming and fabrication, Eastman claimed.

The New Uses Committee of the United Soybean Board is sponsoring five projects researching plastics made from soy oil and protein.
``Soy protein offers a number of unique properties that could be valuable to industrial manufacturers,'' according to Walt Rupprecht, consultant for St. Louis-based USB.
These attributes include de-gradability, fire resistance, coatability, absorption, ultraviolet and infrared transmission, and anti-static and dielectric characteristics. The projects are designed to use these properties to make commercial products. Potential applications are flexible disposable films, rigid urethane foams and composites.
USB is funding projects at five universities:
Iowa State University in Ames, Iowa, is researching and cataloging soy properties that might be useful in making plastics.
The University of Missouri in Columbia, Mo., is evaluating rigid polyurethane foams made from soy protein.
Purdue University in West Lafayette, Ind., is synthesizing and characterizing soy fatty acid and carbohydrate ester biopolymers for injection molding and extrusion.
Pittsburg State University in Pittsburg, Kan., is developing plastic materials from soy oil using urethane chemistry.
Michigan State University in East Lansing, Mich., is developing extruded plastic films from soy protein for potential use in agricultural mulching film, trash bags and grocery sacks.
