SAP

Super absorbent polymer (sodium polyacrylate)

SAP is a cross-linked polyacrylate powder that holds hundreds of times its weight in water as a gel. It is the absorbent core of hygiene products (diapers, incontinence pads) and the active material of cable water-blocking tape. In agriculture it retains soil moisture; in the cold chain it fills ice packs.

Overview

SAP is the standard grade of the SAP family in the general-purpose plastics group. It is used in applications such as diapers and hygiene products, cable water-blocking tape and yarn, soil moisture regulator in agriculture. The grade with the right flow for injection, extrusion or another process is specified in the quotation together with your quantity and colour; TDS and SDS are sent with the quotation.

Tensile strength is measured to ISO 527, melt flow rate to ISO 1133, heat deflection temperature to ISO 75 (1.8 MPa); flammability class per UL94. Depending on supplier and grade, values can fall outside this range.

Applications

  • Diapers and hygiene products
  • Cable water-blocking tape and yarn
  • Soil moisture regulator in agriculture
  • Ice packs and cold chain

Documents

The supplier's technical data sheet (TDS) and safety data sheet (SDS) for SAP are sent by e-mail with the quoted grade; because the same code has different sheets at different suppliers we do not publish a single file on the site. To see the sheet in advance, request it with the link below.
