PFA Call for Papers
Polyurethane Foam Association Accepting Abstracts For Technical Presentations For November 2019 Meeting
Abstract Deadline: September 15, 2019
LOUDON, TN (August 6, 2019)—The Polyurethane Foam Association is accepting proposals for technical presentations for its Fall Technical Program, November 7, at the Brown Hotel in Louisville, KY.
Authors must submit an abstract with request for presentation. Presentations must not exceed 25 minutes in length. A written paper and slide file are also required to become part of PFA’s online information library.
The Paper Selection Process
To be eligible for presentation, papers must have a non-commercial focus and specifically address topics related to slabstock or molded flexible polyurethane foam production, raw material developments, environmental performance, occupational safety, product evaluation, novel commercial applications, or production control, and be based on actual production applications.
The deadline for submitting an abstract is September 15, 2019. To submit a proposal or for more information, please contact Russ Batson by email ( rbatson@pfa.org ) or telephone (865.657.9840). Three topics have already been proposed, so potential speakers are advised to act quickly.
Based on a program that includes at least 6 technical papers, the presentations will be scored to compete for a $500 Technical Excellence Award provided by the Herman Stone Family Endowment.
About The Polyurethane Foam Association
The Polyurethane Foam Association is a trade association founded in 1980 to educate customers and other groups about flexible polyurethane foam (FPF). This includes providing facts on environmental, health and safety issues and technical information on the performance of FPF in consumer and industrial products. FPF is used as a key comfort component in most upholstered furniture and mattress products, along with automotive seating, packaging, medical products, and numerous other applications.

First Order of Polyurethane Wind Blade
Covestro: First ever order of PU resin for wind blades delivered
Covestro announced that it has delivered its first commercial order of polyurethane raw materials for wind blades to China. According to the World Wind Energy Association, China is the world’s largest wind power market with 221 GW of installed capacity at the end of 2018.
The blades, produced by Zhuzhou Times New Material Technology (TMT), one of the largest manufacturers of wind blades in China, have then been delivered to the wind turbine technology company Envision. They are scheduled to be installed in a wind farm in East China in July 2019.

Covestro delivered polyurethane resin to TMT for the production of 18 polyurethane wind blades of 59.5-meter-length, also for the spar caps and shear webs. These blades were delivered to Envision, heralding the successful deployment of Covestro’s polyurethane resin in blades for commercial wind farm projects. To ensure successful deployment, the Covestro wind power team produced a prototype of the wind blades which has passed static and fatigue tests. The prototype was put into trial operation at a wind farm in central China in 2018.
Ulrich Liman, Global Head of R&D, Business Unit Polyurethanes at Covestro said, “We are very excited to be working with Envision and TMT on this first sales order of PU wind blades in China. Polyurethane resin in the production of wind blades, is a game-changing innovation delivered by Covestro teams around the world. We remain committed to our vision of creating products that benefit society and improve people’s lives all over the world.”
Zilu Liang, Deputy Chief Engineer, Wind Power Products at TMT, said, “As an innovative material, polyurethane, compared to epoxy resin, has advantages in costs and in the production process. We have cooperated with Covestro since 2016, and now we have achieved continuous production. We hope to further collaborate with Covestro to explore large-scale wind blades and wind blades completely made of polyurethane.”
According to Covestro, the polyurethane infusion resin was developed to help the wind power industry meet the growing demand for longer wind blade designs. Wind turbine rotor blades of this kind are typically made out of fibreglass-reinforced resin by applying vacuum infusion technology. The successful use of polyurethane resin for manufacturing large-scale rotor blades for wind turbines suggests that the material itself features superior mechanical properties and anti-fatigue performance. There are also benefits for the production processes in the wind blade factory, for example, a faster curing process and better processing properties to deliver higher productivity levels.
Irene Li, Head of PU Application Development Asia Pacific at Covestro, summarised, “This is the first step to realising the industrialisation of polyurethane resin in the wind industry, opening up a new chapter in polyurethane chemistry. We believe that our polyurethane solution delivers significant advantages in wind blade production and along the value chain.”

Tempur-Pedic Cooling Technology
Tempur-Pedic Creates World’s First Mattress That Stays up to Eight Degrees Cooler Through the Night
“Sleeping cooler, and in particular, sleeping cooler throughout the night, is the number one unmet consumer need in the sleep industry — with more than 60% of Americans struggling with this problem — and the new TEMPUR-breeze is the only mattress line that truly addresses it,” said Rick Anderson, Tempur Sealy EVP and President, North America. “TEMPUR-breeze mattresses are a thermodynamic breakthrough that provide both unbeatable all-night cooling and maximum pressure relief for a deeper, more refreshing sleep.”
Tempur-Pedic’s thermal, material and textile scientists — including ten cross functional teams across three continents — have spent more than ten years and 2.6 million hours on R&D in the industry’s most sophisticated Thermal Lab. Building on this commitment to innovation, the new TEMPUR-breeze mattress performs exceptionally at each layer — and for the first time in the industry — across the whole system. This coordination addresses temperature and humidity flux in the sleep microclimate during three separate phases of sleep:
- When you lie down: The high molecular weight yarn in the SmartClimate® Dual Cover System delivers a cooling sensation up to 30 percent more intense than non-cooling models. Thermal effusivity tests—which measure heat absorption—confirm this cool-to-touch yarn absorbs heat throughout sleep, continually feeling cool as you roll over and adjust. With a washable, easy-to-remove cover that features a patent-pending 360-degree zipper system, cooling effects will not diminish.
- As you fall asleep: At about 80°F, the molecules within TEMPUR-breeze’s most efficient Phase Change Material (PCM) to-date, PURECOOL+™, activate, shifting from a solid to a liquid to absorb massive amounts of heat. For the first time, Tempur-Pedic’s scientists successfully altered these proprietary molecules to deliver more phase change material, increasing its capacity to absorb heat by 2x compared to other PCM.
- Staying cool all night: In an unprecedented engineering feat at a cellular level, TEMPUR-CM+™ comfort layer is up to 10x more porous to more effectively channel heat and humidity away from you all night long. For the first time, both phase change and climate materials are integrated into the bed’s top layer where they’re most effective.
Coolness and comfort in concert
TEMPUR-breeze delivers the highest performing cooling system and most advanced pressure-relieving material in one mattress. On a molecular level, the ability to combine Tempur-Pedic’s pressure relieving, adaptation and motion-isolating properties with open-cell foam material is an industry-first. Tempur-Pedic is the only brand to successfully engineer this into soft, medium and firm feel preferences.
Perfect temperature every time
From cover to core the TEMPUR-PRObreeze™ and TEMPUR-LUXEbreeze™ mattresses combine the best cooling performance and pressure relieving properties in Tempur-Pedic’s history. The new TEMPUR-breeze line includes PRObreeze™, which features three-level cooling system and feels up to 3 degrees cooler through the night. It’s available in medium and medium hybrid and retails at a price point of $3,799 for queen-size.
The LUXEbreeze™ also includes the company’s most advanced pressure relieving material in a ventilated TEMPUR-APR® support layer, delivering even more breathability and cooling comfort for four-levels of cooling technology. As a result, it feels up to eight degrees cooler through the night. Available in soft and firm versions, the LUXEbreeze retails at $4,499 for queen-size.
