Investigation Reveals Georg Fischer Exported Military-linked Goods to Israel During Gaza War

Swiss Company Suppled Products to Companies Linked to the Israeli Defence Ministry
Georg Fischer AG, based in Schaffhausen and specialising in piping systems for transporting water, chemicals and gas, exported valves – costing between CHF100 and CHF500 each – used to regulate fluid flow. These were supplied in particular to the Israeli refinery in Ashdod, whose customers include companies linked to the Israeli defence ministry, according to a report by the Dutch NGO SOMO.
Another Israeli client of Georg Fischer is Israel Chemical, which several NGOs accuse of producing white phosphorus for military purposes, particularly in incendiary weapons. Although its use is legal in some contexts, the chemical agent is highly controversial.

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.

BREAKING NEWS

New Lawsuit: Harmon et al v. Uponor Inc.
New Class action Lawsuit Filed Against Uponor Corporation Alleging that Plastic Plumbing Pipes Manufactured by the Company Caused Property Damage Due to Premature Failures
The case, Harmon et al v. Uponor Inc., Case No. 0:26-cv-01140, was filed on 6 February 2026 in the U.S. District Court for the District of Minnesota. The complaint was brought by plaintiffs Lindsey Harmon, Maribeth Borroughs, and Seunghun Kim, who claim that defective plumbing components produced by Uponor led to leaks and damage to residential properties.
The lawsuit is categorized as a property damage product liability action and has been filed as a putative class action, meaning the plaintiffs seek to represent a broader group of homeowners or property owners who may have experienced similar problems with the company’s plumbing pipe systems.
According to the complaint, the plaintiffs allege that Uponor manufactured and marketed plumbing pipe systems that can fail prematurely under normal operating conditions, potentially resulting in water leaks and significant property damage.
The plaintiffs are represented by attorneys from the law firm Berger Montague

Belgian Pipe Manufacturer Aliaxis Slips into the Red / Sale of German Business Unit
2025 and 2026 are proving difficult years for pipe manufacturer Aliaxis. Demand from end markets was significantly weaker, particularly in the construction sector, leading to falling volumes and profitability.
The group reported revenue of around EUR 3.5 bn, representing a decline of roughly 6.8% year-on-year. Operating earnings also dropped sharply, with recurring EBITDA falling to EUR 364 mn, around 31% below the previous year.
Due to exceptional items and restructuring effects, the company ultimately slipped into the red, posting a net loss of about EUR 68 mill for 2025. Recurring net profit, excluding these items, still amounted to roughly EUR 50 mn, but this was down sharply compared with the prior year.
Management attributed the downturn mainly to softer demand across global construction markets, with the US market proving particularly weak, putting pressure on the group’s North American operations.
As part of a broader programme to streamline the portfolio and strengthen the balance sheet, Aliaxis divested several assets, including the sale of its Marley Germany business. Additional measures included the sale of real estate and idle assets in the UK and Mexico, the exit from the Chilean market, and the closure of an exploratory research facility in France.  The company said it will continue focusing on cost reductions, asset optimisation and cash generation as part of its Horizon 2030 strategy, aimed at improving resilience and preparing the group for an eventual recovery in construction activity.

WTF ! – ABCB Rules Plumbing Products Containing Lead Will Remain Legal to Install in Australia Until 2028
Plumbing products containing lead will remain legal to install in Australia until 2028, after the national building authority extended a phase-out deadline by two years.
The Australian Building Codes Board (ABCB), which sets national construction standards, said the delay was necessary due to “insufficient” availability of lead-free certified products.
According to the Plumbing Industry Climate Action Centre (PICAC), this means the vast majority of plumbing products, which contain between 4.5 per cent and 6 per cent lead content, can continue to be installed into Australian buildings until May 1, 2028.
It comes three years after the board declared only certified copper alloy products with less than 0.25 per cent lead content could be used to convey drinking water as a way to address the health effects caused by lead.

Borouge and SABIC Expected to Announce to Hike PE100 HDPE Resin Prices Due to Iran Conflict
Heightened security risks across Middle East sea lanes because of the US-Iran conflict is disrupting polyethylene (PE) and polypropylene (PP) supply and delivery.  Heightened security risks across Middle East sea lanes because of the US-Iran are disrupting polyethylene (PE) and polypropylene (PP) flows as carriers suspend sailings and impose emergency surcharges.  Despite the cost surge, vessel space remains constrained as shipowners cut departures on high-exposure routes and roll bookings.  A large share of HDPE using Borealis technology is produced in the UAE through Borouge, a joint venture between Borealis AG and Abu Dhabi National Oil Company. Borouge operates a major petrochemical complex in Ruwais.  The facility produces polyethylene (including HDPE and bimodal pipe grades) using Borealis Borstar® technology.  US-Israeli strikes on Iran closed the Strait of Hormuz, threatening 1.125 million tons of PE supply to China.  Exacerbating the situation SABIC swung to a massive net loss in 2025 ‌due mainly to impairments and losses related to the divestment of assets in Europe and the Americas while separately announcing a new CEO last week.

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.
