Technical Bulletin 0714

Elastomeric Insulation versus

Polyisocyanurate in

Low Temperature Applications

PURPOSE

Several of Dyplast’s prior Technical Bulletins have provided in-depth comparisons of various insulants, including polyisocyanurate (polyiso or PIR), polyurethane (PUR), phenolic, polystyrene (expanded EPS and extruded XPS), cellular glass, and fiberglass - - as well as less-than-comprehensive comparisons with elastomeric and aerogel. Now with somewhat more information becoming available from elastomeric manufacturers and the aggressive marketing from elastomeric suppliers for colder applications it is appropriate to dedicate a Technical Bulletin to elastomeric insulants as compared to polyisocyanurate - - and to a much lesser extent phenolic, and cellular glass.

QUICK PERSPECTIVES

The most basic perspective is that the overall cost of elastomeric insulation is materially higher than polyisocyanurate, and polyiso also has significantly better thermal insulation properties - - thus raising the question of “why use elastomeric”:

What You Should Know About Thermal Conductivity and Aging of Low-Temperature Mechanical Insulation

Technical Bulletin 0414

What You Should Know About Thermal Conductivity and Aging of Low-Temperature Mechanical Insulation   This Technical Bulletin is another in Dyplast's series to provide objective information to decision-makers and end-users on important issues related to mechanical insulation (i.e. insulation for equipment). Although technically intense in some paragraphs, this Technical Bulletin objectively encapsulates more than can be gleaned from other documents generally available.   Thermal aging is a term that refers to the tendency of some insulants to lose some thermal resistance over time - - predominantly due to the very slow diffusion of low-thermal-conductivity cellular gases out of the cells within the insulation, only to be replaced by "air" with higher thermal conductivity. Since thermal aging is so often used as an argument for or against a particular insulation, it is important to understand this somewhat complex phenomenon.   It is even more important to understand that aged polyisocyanurate still has better thermal conductivity than other insulants that may not age.   CLICK HERE TO READ THE FULL TECHNICAL BULLETIN 0414

Dyplast responds to receiving NIA's Theodore H. Brodie Safey Award

 

 

 

Dyplast CEO Ted Berglund responds to receiving NIA’s

Theodore H. Brodie Distinguished Safety Award.

"Our safety team was very excited to be part of NIA's safety award program and to get the detailed analysis of our safety program. This feedback helped our team improve Dyplast's program and resulted in a platinum award in our second year. The feedback helped Dyplast improve our employee participation and reduced our insurance costs. Our insurance broker informed us that the carrier considered this award during the underwriting process. But the most important benefit was the pride in recognition of the team's efforts. Everyone at Dyplast believes that this award program, including the process of reviewing our program and receiving feedback, is a true benefit to our company."

-Ted Berglund, President & CEO, Dyp/ast Products, LLC

 

The award is named in honor of NIA Past President Ted Brodie, who worked tirelessly for many decades before his death in 2010 to create a greater awareness of the need for safe working conditions. M r. Brodie first chaired the association's Health and Safety Committee in 1967, and he received N IA's President's Award in 1988. M r. Brodie was the President and CEO of New England Insulation Co., Inc. in Canton, Massachusetts, for 50 years.

 

Dyplast awarded the 2013 Theodore H. Brodie Distinguished Platinum Safety Award

 

The National Insulation Association (NIA) announced the 2013 Theodore H. Brodie Distinguished Safety Award winners at NIA's 59th Annual Convention in Indian Wells, California. The Theodore H. Brodie Distinguished Safety Award is NIA's highest industry honor for outstanding safety performance. Michele Jones, NIA's Executive Vice President/CEO, affirmed, "NIA strongly feels that safety is absolutely crucial for our industry, and we applaud companies who take steps to make safety a top priority." The winners of this safety award have prioritized safety by establishing structured safety programs to create safe working environments and ensure the well-being of their employees. NIA received a record number of applications this year, and is pleased to report that the program is recognizing more companies for their safety programs than ever before.

Technical Bulletin 0314 - Phenolic vs. Cellular Glass Insulation in Cold Piping Applications

10 March 2014   Technical Bulletin 0314

Phenolic vs. Cellular Glass Insulation in Cold Piping Applications   A short summary is included below. Click here for the complete Technical Bulletin   Phenolic and cellular glass mechanical insulation have each been demonstrated as viable choices for cold applications when 25/50 (per ASTM E84) is required, particularly in chilled water applications. This Technical Bulletin offers an objective comparison - - with the conclusion that when comparing both side by side, the overall advantages clearly belong to phenolic. The new phenolic is not the old phenolic New catalysts with minimum detectable halogens Low water absorption (the difference between 0.9% for phenolic vs. 0.2 for cellular glass is not material) Phenolic with 60% better insulating value 0.18 versus 0.30 at 50°F 2.5 inches versus 4.5 inches thickness in a typical 50°F scenario Phenolic is roughly 67% lower cost per board foot Plus lower fabrication/installation costs #2 and 3 above when taken together puts phenolic capital costs possibly at one-third that cellular glass - - and that's ignoring fabrication and installation Phenolic is one-third the weight of cellular glass 6 times more weight per linear foot in the 2.5 vs 4.5 inch scenario   In summary, both phenolic and cellular glass have been demonstrated as viable choices as insulation for cold applications when 25/50 is required. However, when comparing both side by side, the overall advantages clearly belong to phenolic.   Below is a link to the full Technical Bulletin   TECHNICAL BULLETIN 0314
