Innovation: Waterproof boards
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Scientists in Wales have developed a cheap way of making waterproof chipboard.
Standard chipboard has a big drawback - when it gets wet it swells and falls apart. Waterproof glues are available for making weather-resistant boards, but cost several times as much as soluble glues.
Now the Biocomposites Centre in Bangor has found that a chemical called phthalic anhydride (PA), produced in large quantities for the plastics industry, can be substituted in part for waterproof glue.
BP Chemicals, which is the largest producer of PA in the UK, has financed the research.
