DSM offers PU line, thermoplastic grades
DSM Engineering Plastics of Evansville, Ind., extended its Fiberstran line to include long-glass-fiber-reinforced rigid polyurethanes designed to replace metals in abusive applications.
It offers grades with glass loadings as high as 50 percent.
This grade has notched Izod impact of 9 foot-pounds per inch, flexural modulus of 1.85 million pounds per square inch and tensile modulus of 1.9 million psi.
List truckload prices begin at about $3.46 per pound for the 30 percent filled grade. (Quick Information Card No. 111)
Also from DSM Engineering, controlled resistivity is offered in new conductive thermoplastics.
New Electrafil grades have consistent resistivity in the static dissipative range, despite processing variations, to eliminate the potential for the compound to become fully conductive, the company claims.
DSM targets the compounds for uses in such products as integrated circuit chip trays and burn-in test sockets. (Quick Information Card No. 112)
New Epolin product targets infrared
Epolin Inc.'s Heat Shield 900 absorbs infrared light to help prevent heat buildup in glazing applications.
The product allows 70 percent of visible light transmission while cutting total solar transmission by 75 percent.
It can be processed into polycarbonate and dyed into acrylic and other films. It imparts a tan or gray color to most plastics. Epolin supplies it as a powder and in compound form.
Epolin is based in Newark, N.J.

Huntsman introduces R-Mer expanded PS
Huntsman Chemical Corp. introduced R-Mer expanded polystyrene bead as a lower-costalternative to expanded polyeth-ylene and expanded polypropylene.
R-Mer is polymer modified to make it resilient for applications such as electronic and appliance packaging designed to withstand multiple drops. Spokesman Lester Hellewell said a major electronics firm saves $125,000 per month after switching to R-Mer from expanded PP.
Huntsman of Chesapeake, Va., claims R-Mer can be processed on conventional EPS equipment using pentane blowing agent. It said the product processes faster than EPP or EPE at low densities. List price is about $1.80 per pound.

Concentrate suited for metallocene film
A. Schulman Inc. introduced anti-blocking and slip concentrates for metallocene resin-based blown and cast films.
The Polybatch Ext series, based on metallocene resins, include Schulman's proprietary surface modification technology.
The concentrates are suited for metallocene film resins ranging from rubber-like grades to high-clarity, tough resins.
The Akron, Ohio-based firm also reported the addition of UL-rated flexible vinyl to its existing Polyvin PVC line. The new electrical grades will be well-suited to appliance, business machine and electrical markets.
These materials will complement the flexible vinyl Schulman supplies to the automotive interior and exterior and consumer goods markets. Grades ranging from 65-85 Shore A durometer are available in clear, black and colors. The new PVCs are available for distribution in the United States and Canada.
Schulman is a supplier of high-performance plastic compounds and resins. The firm specializes in custom-formulated, engineered compounds matched to individual customer product specifications.

New pigment serves outdoor application
United Mineral & Chemical Corp. of Lyndhurst, N.J., began distributing a new phosphorescent pigment in North America.
It claims LumiNova has 10 times initial brilliance and afterglow time compared with zinc sulfide copper activated types.
The inorganic oxide is nonradioactive. Its weather resistance makes it suited for outdoor applications. It is activated by UV light and is recommended for a range of clear and translucent plastics. LumiNova, supplied as a powder and in tape form, was developed by Nemoto & Co. Ltd. of Tokyo.
