Hello Future 4200! This is my first post here. I would like to bring your attention to SolventlessSelect.com. We inherited PurePressure’s products and vendors after Agrify closed down. Original PurePressure and Precision Extraction technical experts remain on our team as well.

The same parchment paper and press filtration bags (PurePacks) everyone trusted and loved are still available through Solventless Select. Our products do not come from China. The parchment and filter bags are manufactured here in the USA under strict cleanliness in order to ensure your extracts remain contamination free. The fabric used in PurePacks comes from our trusted friends in Italy and is guaranteed to have medical-grade micron consistency. The filter bags are doubled (25μm inner bag and a 120μm outer bag) and without sewing stitches, they are connected using ultrasound. Bags from China have horrible micron consistency and are more prone to blowouts due to their inferior stitching and materials. I know this with certainty because I was the one who evaluated this sort of thing at Agrify/PurePressure. I’ll try to upload some microscopic pictures of China’s filtration bags vs PurePacks so that you can all see the difference.

Subscriptions for parchment paper and PurePacks are available at a discounted price as well. Don’t forget to use the coupon code above for 10% off parchment orders until January 31!

Thank you and let me know if you have questions! More information is available on our website. I appreciate your interest in us!

Hello @BigM, thank you!!

How much pdms/silicone oil is leached into the rosin from your paper?

Great question.

There shouldn’t be anything leaching from the parchment during our cannabis centric processes. If there was a known problem with silicone coated parchment, the FDA would not have approved it as food safe. For more information on how this sort of parchment paper is created, visit Behind the Scenes: The Chemistry Behind Silicone-Coated Baking Paper - Baking Paper& Parchment Paper Manufacturer . “At the molecular level, the silicone used in baking paper is typically made from polydimethylsiloxane (PDMS)—a highly stable, food-safe polymer. During the manufacturing process, PDMS is cross-linked using heat and a catalyst (such as platinum or peroxide) to form a durable, flexible, and inert layer bonded to the paper.” That process is what prevents the coating from coming off the paper and into your product.

If you are referring to silicone exposed to heat, your concerns are legit. We are aware of some published research showing the dangers of exposing silicone based products to prolonged, intense heat. https://www.researchgate.net/publication/281392502_Heat_stability_and_migration_from_silicone_baking_moulds

That link should pull up the research paper showing the problems that occur when heating silicone at high temps for an extended amount of time. They conclude that everything remains inert (safe to use, no leaching, no contamination) up to temps of 100C (212F). Above 150C (302F) is when the problems start to occur.

During a bubble hash press, temps are normally around 160 to 180F (71 to 82C). I think it would be unusual to be pressing anything at temps over 200F but according to that paper, we have nothing to worry about until about 300F. There is also a huge difference in heat exposure time. Those researchers are heating the silicone products for hours and our pressing takes about 2 minutes.

Would you happen to know of any other research into this subject? I’d be interested in reading it. We definitely want to be ahead of problems such as this, but I believe we are currently safe. I hope I have eased your concern!
