Modifier designed to boost productivity
A new polymer modifier promises to improve productivity and lower costs, according to the developer, International Technical Polymer Systems Inc.
The Niles, Ohio, firm said its Intec additive modifies polymer rheology to enhance flow properties of a range of thermoplastics and elastomers.
ITPS also said the modifier can cut molding time and lower power draw in extrusion without affecting a part's physical properties. In mixing, it can reduce cycle time and improve dispersion.

TPEs have improved substrates bonding
RTP Co.'s new thermoplastic elastomers were developed for improved bonding in overmolding onto a range of substrates.
The firm said the first two commercial grades have hardnesses of 45, 55 and 75 Shore A. RTP 6002 is suited to bonding to polycarbonate, ABS and alloys of the two resins.
RTP 6003 is targeted for bonding to PC/polybutylene terephthalate and to PC/acrylic compounds.
Improved bonding also means the materials offer molders a wider processing window, according to the Winona, Minn., company.

Markel touts tubing extruded from PTFE
Markel Corp. has developed a precise method to make microporous polytetrafluoroethylene tubing.
The Plymouth Meeting, Pa.-based company said its Market EXPT-brand PTFE tubing can be used to extract gases from liquids and to inject gases into liquids.
Markel manufactures the tubing by continuously stretching paste-extruded PTFE resin, creating nodes and pores. The company claims it can control microporosity, which is locked in during a sintering stage.
Potential uses include extracting methane from animal waste, ozone injection in water purification and water clarification in aquaculture.

Rubber targets uses needing to resist oil
Cleveland-based Ferro Corp. has introduced a melt-processable rubber series geared to medium-engineered injection molding applications.
The firm's Advanced Polymer Alloys division in Wilmington, Del., said Alcryn MPR 2300 features durability, chemical resistance and fast cycle times at a lower price than premium Alcryn MPR grades. The materials now are available in black, but colorable versions are due by midyear. Hardness values are 60, 70 and 80 Shore A.
The firm claims the new materials bond well to PVC and provide good tensile and tear strength. They are aimed at markets in which oil resistance and durability are key, such as transportation, marine and wire and cable.

New Gate-Mate Lite extends nozzle sizes
D-M-E Co. has expanded its Gate-Mate Lite, a successor to the Gate-Mate 4 nozzles for thin-wall parts, direct part gating and high-cavitation molding.
Gate-Mate Lite now is available in 10 nozzle lengths, from 42-130 millimeters, and is suitable for multicavity molds.
Features include a square coil heater and an integrated thermocouple to ensure an accurate temperature profile. The tip is made from a highly conductive beryllium copper.
D-M-E, headquartered in Madison Heights, Mich., is part of Milacron Inc.

Extrusioneering has compounding course
You can take a one-day class at Twin Screw University, courtesy of Extrusioneering International Inc. of Randolph, N.J.
The intensive training course in compounding technology is scheduled frequently around the country. Sample topics include compounding operations, modular screw design, computer simulation and optimization, trouble-shooting and scale-up.
For information, contact the company at (973) 895-4088.
Software made for co-rotating extruders
The University of Akron and the Akro-Co-Twin Screw engineering staff have issued Version 4 of a personal-computer-based extrusion simulation and modeling software program that runs on Windows for users of co-rotating twin-screw extruders.
The extruders are used for virgin resin production, compounding, blending, devolatization and reactive extrusion.
* Residence time and temperature profiles for reactive extrusion (REX).
* A REX module with consideration of reactions, kinetics and yields for polyolefin materials and dynamic vulcanization.
* Predictions of devolatilization processing and screw-temperature profile.
* Increased ability to model things that happen during melting, including when the barrel temperature is below the polymer's melting point.
The university is marketing Akro-Co-Twin Screw through Temarex Corp. of Akron, Ohio.

Pipe extruder uses QuickSwitch lines
Pipe extruder Egeplast Werner Strumann GmbH of Greven, Germany, has converted four of its lines to the QuickSwitch line from Krauss-Maffei Kunststofftechnik GmbH. QuickSwitch allows push-button diameter changes, without ever stopping pipe extrusion.
``Dimension change costs have dropped by 90 percent compared with a conventional production line,'' said Ansgar Strumann, managing director.
Krauss-Maffei is in Munich, Germany. The U.S. unit, Krauss-Maffei Corp., is in Florence, Ky.

Classifier handles big, small particles
Witte Co. Inc. of Washington, N.J., introduced its 700 Series plastic pellet classifier for compounders, recyclers and other extrusion companies that demand a high degree of pellet uniformity.
The 700 removes both oversized pellets and fines. The material meets the screen as a single, thin and even layer by accepting pellets through an inlet cover and spreader, then settling them onto a metal distribution deck.
The machine can be opened without any tools. Witte said one person can disassemble the classifier in less than five minutes.

Sheet is pre-shaped, then thermoformed
A patented process from vacuum forming machine maker International Molding Equipment of Vancouver, Wash., pre-shapes sheet before thermoforming, and allows for easy removal of parts with difficult draft angles.
The patent covers an articulated folding frame. First, the sheet is pre-shaped by swinging one or more hinged sections of the frame toward each other. The mold is closed and the part is vacuum formed. Draft angles are no problem because the device flexes the finished part, according to the firm.
The frame now is in production making wraparound rear and front bumpers for cars and recreational vehicles, caps for pickup trucks and large, curving slides for swimming pools.
The firm said the system can be built into a dedicated, specialty machine or added to a standard machine.

Batch blenders offer self-cleaning feature
Atlanta-based Process Control Corp.'s Guardian gravimetric batch blenders now come with a self-cleaning feature for removing all resin from the weigh hopper and mixing chamber at the push of a button.
The hopper and mixing chamber both contain purge points. Pneumatic solenoids are used to cycle air through the ports. When the hopper gate closes, the mixer stops and the mixing gate closes, completing the purging cycle, said the Atlanta auxiliary equipment builder.
