Close-Up on Technology

Economical Toughener for PC/ABS Also Boosts Flow of PC
Impact modifier addresses three key needs.

Novel Device Boosts Feed Rate & Throughput
Feed enhancement unit is aimed at low-bulk density materials.

What’s New in Mold Simulation
Seamless integration with CAD and FEA structural analysis is a common theme among the major software products.

Features

Look Before You Leap: When Direct Extrusion Makes Sense
The process offers great opportunities to extrude a better product at less cost, but it’s not for everyone. The formulation, product mix, and anticipated volumes must be carefully assessed to determine whether DE is the preferred manufacturing methodology.

Mold Filling Simulation: What, When, Why, How
Mold-filling analysis is the right direction to go, but if you want to arrive at your destination—good parts and an efficient process—you’ll need to pay attention to all the details and select an experienced professional to do the analysis.

Novel Fuel Systems Power Blow Molder’s Growth
Nano technology gives The Plastics Group a leg up on developing fuel systems for non-automotive applications

Energy Miser: Reducing Compressed-Air Usage
Many manufacturing sites operate on the assumption that compressed air is free. Usage is totally uncontrolled, and open air lines cost real money.

Strategies

A Pioneer in ‘Clean Compounding’
When Plastics Color Corp., based in Calumet City, Ill., established a new compounding plant in Southern California, the firm decided this couldn’t be an ordinary color/additive masterbatch facility.

Keeping Up With Technology

ADDITIVES: Additive Masterbatches for Security, Barrier, Durability, Processability & More
Denesting aid for thermoformed and injection molded packaging also helps with mold release and scratch reduction.

ADDITIVES: A New Toolkit for Modifying PLA
New additives boost performance, processability, and appearance of biopolymer.

INJECTION MOLDING: Two New Electric Presses
High-speed machines for clean room medical and packaging.

INJECTION MOLDING: Smaller Hot-Runner Pitch And Two-Piece Edge Gates
Smallest flat line nozzle allows cavity spacing of 5.5 mm.

RECYCLING/SCRAP RECLAIM: Heavy-Duty Pipe Shredders
Designed to handle PVC, PE, or PP pipe up to 47 in. diam. with no pre-cutting.

RECYCLING/SCRAP RECLAIM: Melt Filter for Highly Contaminated Scrap
Reportedly can filter plastics with contamination levels up to 16%, vs. 0.5% to 1% for conventional filters.

MATERIALS: Clear Styrene-Acrylic Gets Tougher
WEB EXCLUSIVE: Ineos Styrenics, Channahon, Ill., has added a second, tougher grade to its line of Clearblend styrene-acrylic copolymers.

MATERIALS: Carbon Nanotubes Add ESD Protection
WEB EXCLUSIVE: The first grades in the new Stat-Tech NT line of plastic compounds containing low levels of carbon nanotubes have been launched for electrostatic dissipation (ESD) protection of electronic devices and packaging.

WEB EXCLUSIVE: LTL Color Compounders Inc., Morrisville, Pa., has been named an authorized color compounder for AvaSpire polyaryletherketone (PAEK) resin from Solvay Advanced Polymers LLC, Alpharetta, Ga.

MATERIALS: New PC and TPUs for Medical Uses
WEB EXCLUSIVE: A high-flow polycarbonate and three TPUs have been introduced for medical applications by Bayer MaterialScience LLC, Pittsburgh.

MATERIALS: A Variety of New Styrenic TPEs
WEB EXCLUSIVE: Two suppliers recently introduced three lines of styrenic TPEs for a wide range of uses.

MATERIALS: Biobased Thermoplastics Move Up the Property Scale
WEB EXCLUSIVE: Four suppliers are bringing out higher-performance materials partly or wholly based on PLA biopolymer.

MATERIALS: PEI Resists H2O2 Gas Plasma Sterilization
WEB EXCLUSIVE: New tests results published by SABIC Innovative Plastics, Pittsfield, Mass., show that its Ultem polyetherimide (PEI) resin resists hydrogen peroxide gas plasma sterilization better than polyphenylsulfone (PPSU), another amorphous high-temperature engineering thermoplastic.

MATERIALS: Copolyester Gains Renal Care Applications
WEB EXCLUSIVE: Eastman Chemical Co., Kingsport, Tenn., has reported two commercial applications in renal-care devices for a special grade of its proprietary Tritan copolyester that was developed specifically for this market.

Know How

Dead Screw Talking
There's a lot you can learn by conducting a post-mortum examination of your screw.

The Tools of Tool Maintenance
The root cause of many mold and part issues are ultimately determined by the ability to measure something within one or two tenths of a mil. Readings with precision measuring tools can determine whether a tooling component is to be reused, reworked, or scrapped out.

Resin Prices

Commodity & Engineering Resin Prices Heading Lower
Entering the third quarter, prices of the four commodity thermoplastics are expected to be flat or lower. The outlook is similar for “commodity” engineering resins—ABS, PC, and nylon 6 and 66. Reasons include lower feedstock costs, slowed demand, improved supply, and low exports.

Recycled Resin Prices

Lower Prices Expected
Some of softness is the result of pressure from sagging virgin prices. The economic outlook is a factor too.
