BREAKING NEWS

Iplex Pipes Class Action Update
Homeowners may be entitled to compensation — even without visible damage

Iplex Files Cross-Claim in Case of Tracey Ellen Watters v Iplex Pipelines Australia Pty Ltd
The case concerns a particular type of plumbing pipe: the “Pro-Fit” polybutylene pipes manufactured with “Typlex-1050 resin.”
The claim alleges these pipes are defective: they have a high propensity for “crazing, cracking, rupture and leaks” rather than being fit for their intended use.
The defects are said to breach consumer-protection laws — specifically failing the statutory guarantee of “acceptable quality” under the Australian Consumer Law.
Additional claims include that the defendant engaged in “misleading and deceptive conduct” in how the pipes were supplied/marketed.

Forsyth Barr Investment Services Reduces Governance Score on FBU
The Governance score continued to fall and is now rated “C” as we upweighted the controversies metric, which includes the Iplex polybutylene pipes issue in Western Australia (WA)

PP PIPES

Recycled polypropylene enters pipe systems under rising mandates, yet impurity control ultimately governs crack kinetics and service life
A recent industry-report warns that using recycled polypropylene (PP) for pipes — increasingly required under circular-economy / sustainability push — can compromise lifetime performance. Specifically, impurities in recyclate can accelerate “crack kinetics,” reducing service life of pipes.
For critical applications (e.g. water supply, sewage), the trade-off between sustainability and durability of plastic pipes must be carefully managed.

ExcelPlas Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason.  The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.

Update on US Antitrust Class Action Against PVC Pipe Manufacturers
In re: PVC Pipe Antitrust Litigation, Case No. 1:24-cv-07639 (N.D. Ill.).
On Nov. 6, 2025, the defendants—polyvinyl chloride pipe manufacturers—in a class-action antitrust lawsuit filed a motion to dismiss the remaining claims after having entered into settlements with each class. The remaining purchaser plaintiffs allege that the defendants used an industry publication—PVC & Pipe Weekly—to conspire to increase prices starting in 2020. The defendants argued in the motion to dismiss that these allegations do not plausibly show any per se price-fixing conspiracy because the U.S. Supreme Court has held that this kind of information sharing does not violate the Sherman Act, but instead constitutes a procompetitive exchange of information. See United States v. U.S. Gypsum Co., 438 U.S. 422, 441 n. 16 (1978). Defendants also argued the plaintiffs have not alleged any direct or circumstantial evidence sufficient to show that the defendants had a “conscious commitment” to a “common scheme” to fix PVC pipe prices, despite having had access to “thousands of emails, notes, and text messages.” For instance, the defendants point out that the plaintiffs’ 520+ page complaints alleged “zero communications with or between Defendants reflecting an agreement on PVC pipe prices.”

ExcelPlas Labs Pipe Failure Investigations
ExcelPlas Labs have created a new benchmark in failure analysis of HDPE, PP-R, PB and PEX pipes in addition to PVC &  CPVC pipes as well as composite GRP and GRE pipes.  When a plastic pipeline fails to perform as intended, our team can determine the root cause of failure (e.g.  oxidative failure, chemical failure, creep failure, over-stress failure, fatigue failure, design failure, etc).  ExcelPlas are experienced with all plastic piping failure modes and mechanisms including Slow Crack Growth (SCG) Rapid Crack Propagation (RCP), Environmental Stress Crack Resistance (ESCR), Oxidative Stress Cracking (OSC), cyclic fatigue, manufacturing defects, and polymer material problems.

ExcelPlas Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason.  The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.

ExcelPlas Strain Hardening Test (SHT) for HDPE Pipes
The SHT in accordance with ISO 18488 is a relatively new, but excellent way to obtain a rapid indication of the Stress Crack Growth (SCG) resistance of your piping material. This tensile test performed at 80°C has become in just a few years the new standard for Batch Release Testing (BRT). And not without reason.  The test requires only a very small amount of material, the results are very reliable with a very low inter-laboratory scatter and the results are available within a few days, regardless of the PE grade. The SHT is usually performed on resin material but it can also be performed on samples taken directly from pipes or sheets. As accredited lab, EXCELPLAS is happy to discuss the possibilities with you, whether it is for BRT, benchmarking, quality control of your (high performing) PE grade or for polymer compliance/ validation.
