PPG Industries Inc. is boosting supply of its chopped-strand glass fiber for PET reinforcement in auto applications.
PPG's Type 3563 provides 20 percent greater impact strength vs. the firm's previous reinforcement. It also has greater strand integrity and generates less fuzz, according to the Pittsburgh-based company.

DuPont Engineering Polymers has a new high-flow polybutylene terephthalate for thin-wall injection molding.
Crastin HF675FR has 30 percent glass fiber, a UL94 V-0 listing and flexural modulus of 1.2 million pounds per square inch.
The Wilmington, Del., firm says the new material is suited for electrical and electronic applications such as connectors. Its high flow eliminates the need for high pressures and melt temperatures to mold such parts.

Sealed Air Corp. developed a series of very tough, blown coextruded films based on metallocene-catalyzed polyethylene from an undisclosed supplier.
The Saddle Brook, N.J., firm makes the film in a five-layer construction aimed at a variety of markets demanding strength and puncture resistance. It can supply the product in thicknesses from 5-10 mils on rolls up to 84 inches wide. One outside layer is designed to provide release properties.

O'Neil Color & Compounding Corp. has capability to make pulverized color compounds and dry colorants for rotational molding.
The Paterson, N.J., company said it can make products as fine as 35 mesh and can include a variety of performance additives such as stabilizers and flame retardants. It offers custom and standard colors.

Key Filters Inc.'s Model KCNC continuous screen changer offers continuous melt filtration to processors that do not require top-of-the line features. The price is about 30 percent lower than Key's Model KCN.
The KCNC is suitable for applications where polymer contaminant levels do not change dramatically. Key, of Woonsocket, R.I., reduced manufacturing costs by designing a simpler logic controller and a shorter chamber for screen discharge.
Both the KCNC and KCN filter extruded plastic through a coil of woven stainless steel filter screen, which advances through the screen changer.

Addex Inc.'s new Addex Reinhold Winder, a center/surface assist winder for film, allows reverse winding without difficult changes in web paths or winder position, according to the Boston company.
A key to the system is a patented retracting knife positioned on the vacuum, lay-on drum. It protrudes for cutting and then moves back into the drum. Before the cut, the drum's vacuum is automatically increased to keep the web from moving. Once the cut occurs, the vacuum is reduced back to normal.
The drum itself is made of lightweight carbon fiber so the drums turn more easily. The drum also does not conduct heat or stick to the web.
A second patent covers the tension control within the winder. Addex said the winder also is available for sheeting, in a back-to-back or face-to-face set-up.
