On the recycling of ethylene vinyl acetate (EVA)
Thread Content
Does any expert know the specific temperature for recycling and mixing EVA waste?
1# hntbbmn Polyvinyl acetate Molecular formula: (C4H6O2)n Description: Colorless viscous liquid or colorless to slightly yellowish transparent glassy particles. Odorless, with toughness and plasticity. Does not stain or age due to sunlight and heat. It softens at around 30°C. Soluble in ethanol, propanol, and benzene; insoluble in water and fats. Relative density (d4) is 1.191, the melting point is 100–250°C, the average molecular weight is 22,000, and the water absorption is 2%–3% (at 25°C for 24 hours). Given that the recycled materials vary in degree of aging, an appropriate amount of antioxidants and cross-linking agents should be added. The processing temperature should not be too high; 100–130°C is a suitable range
Thank you to the two friends above: loveliness:
I would be very grateful if any other friend could provide more details!
Does the original poster have any specific information on EVA, such as the production process and equipment? Could they share it?
I also need some knowledge about EVA; I was wondering if you could share it with me
Urgently need an answer: An acidic odor is produced during EVA regeneration. Is this due to a low pH value? Should it be neutralized with an alkali? And what kind of alkali should be used since it is a solid?
