Tin stabilizer works for most pipe applications

Maintain quality while cutting purchasing and inventory costs; those are some of the advantages said to be offered by Thermolite 130 and 135 tin stabilizers, two improved grades now available as part of Arkema Inc.’s established Thermolite product range. Both new grades are claimed to be versatile enough for use as a single stabilizer for most extrusions of rigid PVC pipe.

’s established Thermolite product range. Both new grades are claimed to be versatile enough for use as a single stabilizer for most extrusions of rigid PVC pipe. The advantages in doing so include the potential to lower overall tin content while maintaining quality, and to simplify material purchasing and inventory costs, as well as limit the opportunity for blending errors.

Tin stabilizers are used in rigid PVC applications in North America; much of the rest of the world used lead but has transitioned to calcium zinc or even some organic alternatives.

Arkema Inc. reckons processors of PVC applications such as thin-wall agricultural pipe, high-shear pipe, large diameter pipe, electrical conduit and sewer pipe could benefit from switching to the new grades. Both the 130 and 135 grades can be substituted for others without altering process conditions.

Both new grades have NSF and PPI provisional approval for potable water applications. [email protected]
