Editor's Note: With great sadness I must inform readers that Mike Sepe passed away shortly after writing this article. Mike was an superb writer whose insights on polymers were unmatched. [...]

The concept of an electric vehicle developed nearly 200 years ago, with European and U.S. inventors at the forefront. However, as the electric vehicle was sought after, so too was [...]

A constantly developing automotive industry and the growing number of vehicles generate massive tire demand. The worldwide demand is expected to reach more than 3 billion units by 2025, with [...]

As the rubber industry moves toward its 2030 and 2050 sustainability objectives, it will need raw material suppliers to innovate in support of this effort. One of the principal challenges [...]

As the environmental concerns brought about by global warming and climate change continue to rise, the market demand for sustainable reinforcing carbon materials is increasing. The annual output of new [...]

Pyrolysis has been used as a means of recycling end-of-life tires or other post-industrial and/or consumer rubber products for several years. This process produces several valuable secondary raw materials that [...]

In business for more than 37 years. Growth every year for more than 37 years. And now taking its three pillars of success--loyalty, quality and personal attention--to the highest end [...]

Editor's Note: This article updates a column originally published in the January 2021 issue. At that time, the author was struggling to find a manufacturing partner for the new screw [...]

Follow these best practices to minimize loss of time, material and labor during color changes in molding containers from bottles to jerrycans. The authors explore what this means for each [...]

The 52nd annual Society of Plastics Engineers (SPE) Automotive Division's Blue Ribbon Automotive Innovation Awards once again celebrated several 'firsts' among eight categories, which included innovations in last year's added [...]

Digital printing continues to grow across the board, in markets raging from wide format and ceramics to packaging and textiles (which will be covered in separate features in Ink World's [...]

The following directory lists suppliers of instrumentation and test equipment to the rubber industry, with address, contact person, types of instrumentation, test equipment and services offered. R.D. Abbott Co., Inc. [...]

The following directory lists independent testing laboratories serving the rubber industry, including address, contact person and types of technical service offered by each laboratory. R.D. Abbott Co., Inc. (RDAbbott) 11958 [...]

Rubbers and other elastomeric materials have time-dependent mechanical properties at ambient conditions. This phenomenon is called viscoelasticity, and engineers need to understand visco-elasticity and take it into account when designing [...]

The tensile test is one of the most common physical measurements in the rubber laboratory. Evaluating the average or median stress-strain behavior for five replicate specimens gives a quick and [...]

The time-temperature superposition (TTS) principle relates long test times for various viscoelastic properties at a desired operating temperature to short test times for the same properties at a higher temperature, [...]

ACE Laboratories began as a one-man band working out of a spare bedroom. Any laboratory work that was required to meet their formulation research and development (R&D) assignments was done [...]

Demand for bioresins is growing in molded goods, particularly as a sustainability play to replace fossil fuel-based materials, but these materials are not a drop-in replacement for traditional materials. Molds [...]

One primary goal in any three-plate mold design is to minimize the length of all the parting line openings. Three-plate molds have a taller stack height and at least two [...]

Now the owner of hundreds of injection molding machines, Jeff Green speaks frankly about his company's molding knowledge when he acquired his first presses in 2014. 'We didn't know anything [...]

Siloxane-based additives are broadly used in the coatings industry to provide a variety of performance benefits. As the industry continues to move toward lower volatile organic content (VOC) or near-zero [...]

Introduction The coatings industry has undergone significant transformations in recent years due to the replacement of organic solvent-based coatings by waterborne emulsion latex polymer coatings. Waterborne technology has generated profound [...]

Anyone who has had the pleasure of scraping ice off a car windshield, looking nervously at beautiful but deadly ice spears hanging from winter rooftops, or waiting on a slow [...]

Cellulose, a linear polysaccharide biopolymer, has applications in various industries including food packaging, personal care products, and construction, due to its unique physico-chemical properties, as well as its biocompatibility and [...]

Prices of four out of the five commodity resins were on a downward trajectory heading into December, and polyethylene (PE) resin prices were also reported on that same path, as [...]

Knowledge of three types of densities related to plastic material is required in injection molding. These types are: bulk density, solid density and melt density. This two-part article will discuss [...]

In addition to exhibiting at The Battery Show this October in Michigan, Engel held an open house in Austria with stakeholders in November to show its progress toward replacing steel [...]

'When you look at our investment--our belief in reinvesting in the business--it's ultimately about making people's jobs easier,' says Adam VanMeter, Hoffer Plastics automation project manager. 'If you look at [...]

Fluoroelastomers are high performance polymers that have been around for over 65 years. They were first introduced for the aerospace industry, but have since found use in automotive, oil and [...]

The addition of Molecular Rebar (MR) caibon nanotubes yields impressive performance improvements for resistance to DIN abrasion (30%+), tear (15%+), cut and chip (30%+) and cyclical fatigue lifetime in traditional [...]

The following is a directory of suppliers who offer molding equipment, materials and expertise to the rubber industry. The directory is followed by a cross-reference section listing the companies that [...]

The effective development of components is becoming more reliant on simulations. Allocating resources to precise, early stage design simulations can result in substantial savings by reducing the need for iterative [...]
