I am trying to adhere EPDM to nylon fabric and due to the application it must be food grade (21 cfr) and meet NSF requirements. Due to this I cannot use RFL or isocyanates. This product would be EPDM cured (drum wrap in hot air oven) to both sides of fabric. So far I have tried various ways...
I am trying to increase the tack of an NBR compound and so far am not have much success. Base polymer must be 32ACN or higher content and has a high duro (low oil content). The compound is dissolved in Toluol and MEK and then spread onto fabric. I have tried adding liquid NBR, hydrogenated...
Yes I can change the polymer and I have thought about EPDM. SO far the issue I have found with the EPDM is adhesion to the fabric. Not sure if there is a RFL treatment specifically for EPDM. I have found some EPDMs will adhere to a neoprene RFL but it does not work in this case, I already...
Our initial formulation is using the 3:1 ratio (12 pph:3pph) of ATH to antimony oxide. Although the compound extinguishes it fails the callout and has a Specific Gravity higher than what I would like. Even taking out the antimony altogether I am still high on gravity and failing retardancy...
I am new to this forum and look forward to learning and sharing knowledge with everyone.
I am currently working on a project where the lower specific gravity of the compound the better. This job is a rubber coated fabric (both sides) and has a fire retardancy callout. The fabric is a...
