SAP(Superabsorbent polymer)
A material designed to take up liquid and hold it in a gel-like network. Many hygiene SAPs are based on crosslinked sodium polyacrylate.
Absorbent polymer network
THE NAME, EXPLAINED
What is SAP?
SAP means Superabsorbent polymer.
A material designed to take up liquid and hold it in a gel-like network. Many hygiene SAPs are based on crosslinked sodium polyacrylate.
Worth knowing
SAP is a functional family, not a standard melt-recycling resin. Unused production material is a different enquiry from used hygiene products.
WHY MANUFACTURERS CHOOSE IT01 02 03
Properties with a practical purpose.
Gel formation
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.
Crosslinked structure
This is a typical reason for selecting suitable grades. Check the manufacturer’s data sheet for the actual formulation and service conditions.
Properties vary with formulation, reinforcement, moisture, processing and service conditions. Use the exact grade data sheet for engineering decisions.
THE NEXT-CYCLE QUESTION
What matters when considering recovery?
Crosslinked absorbent polymers do not behave like ordinary melt-recyclable packaging.
SAP is a functional family, not a standard melt-recycling resin. Unused production material is a different enquiry from used hygiene products.
Poly-Cycle can discuss your material information and collection requirements. Inclusion in this guide does not confirm acceptance, a particular recycling method or that every operation takes place at a Poly-Cycle facility.
How assessment and collection workMake the enquiry easier
- Confirm the identity. Keep the manufacturer, trade grade and polymer marking. For an additive or chemical, include the safety data sheet.
- Describe the batch. Give the weight, colour and form: pellets, parts, sheet, film, fibre or another format.
- Explain what else is present. Declare fillers, coatings, metal inserts, other polymers and previous contact with chemicals or other contaminants.
- Agree the route. Share photographs and your collection postcode before arranging a movement.
FROM THE GUIDE TO YOUR MATERIAL
