Jacketing compound improves processing
Furon Co. claims its new chlorinated polyethylene wire and cable jacketing compound solves processing and performance problems typical of such materials.
The Aurora, Ohio, firm said compound 0110-104 has extrusion drawdown capability of 4-to-1 for minimal scrap rates and high extrusion efficiency. It also said the product is highly crack-resistant and resists crack propagation. Furon spent more than two years developing the proprietary formulation.

Egan winders target small-diameter wrap
Davis-Standard Corp. has introduced a series of Egan winders for blown and cast film, Model 1700, targeted for the reel winding of small-diameter stretch wrap.
The 1700 features adhesiveless, fast transfers; center/surface winding; and automatic swing-out core shafts. Programmed inflate-deflate and chucking operations make roll removal easy.
Operators use a color touchscreen to run the unit. Fully automatic guarding prevents the operator from entering the turret area during the winder cycle.
Davis-Standard is based in Pawcatuck, Conn. Egan is in Somerville, N.J.

Injection molders can use CylaCell-PA
Cylatec Inc. has expanded its CylaCell-PA processing-aid offering to include a grade that can be used directly by injection molders, said the Canton, Ohio, firm.
The new product is a linear low density polyethylene-based pellet with inorganic components that improve mold fill and flow, decrease knit lines and sink marks, improve filler and color dispersion and boost part properties, Cylatec claims.
The firm recommends letdown ratios of 50-to-1 to 100-to-1 for injection molders. An official also said CylaCell-PA can boost sheet extrusion productivity.

Corro-Coat applies drip-free coatings
Corrotec Inc. of Springfield, Ohio, has introduced a new coating technology for dip coating and dip molding.
When used for dip coating, Corro-Coat uses an immersion method, giving a completely drip-free finish. Used for dip molding, Corro-Coat prevents the common problem of air entrapment at the mold's low point, according to Corrotec.

Canadian institute develops EFM mixer
The Industrial Materials Institute of Canada's National Research Council has developed a way to mix and blend one polymer into another, Extensional Flow Mixer, or EFM.
The inexpensive, general-purpose mixer, which is patented in the United States, is well-suited for dispersing highly viscous liquids into less viscous ones, according to the institute.
Liquids are forced to flow through the EFM, then the mixture is forced between two circular plates with ridges facing each other. The flow is radial, from the rim toward the center.

Superior-MPM offers Vortex film winder
The Vortex Winder from Superior-MPM Technologies Inc. of Middlesex, N.J., is designed for continuous winding of films in ready-to-ship in-line slit logs, or for master roll sizes.
The Vortex has surface, centerassist and gap-winding capabilities. It turns out rolls with no ``fold over'' at the core and no ``neck down'' during cut-transfer.
The equipment was first developed to be used as back-to-back winders on blown film lines, but it also functions as a stand-alone slitter-rewinder for roll finishing and in-line slitting.

TMI system provides film thickness profile
Testing Machines Inc. of Islandia, N.Y., announced a new TMI profiling system to measure film thickness.
TMI features a fixed-gap capacitance sensor, automatic transport system and real-time graphics.
It includes a measurement and transport unit, personal-computer interface board with cable, the computer and monitor and control software. The user can store as many as 50 setups.
