Stabilizers are essential for PVC processing and provide the finished product with the required properties and durability. Baerlocher stabilizers are sold under the trade name Baerostab and comprise single components as well as complex formulations of these basic components.

The Baerostab range also includes liquid and solid mixed metal stabilizers for plastisol processing, calendering and flexible extrusion, as well as a range of kickers used in applications such as cushion vinyl flooring.

Stabilizer one-packs

Stabilizer one-packs, sold under the trade name Baeropan, are used for the extrusion and injection moulding of both rigid and plasticised PVC. Stabilizer one-packs combine stabilizers (Baerostab) with lubricants (Baerolub) and other additives to provide customised solutions. Baeropan one-packs are designed to match specific requirements in terms of long term stability and durability along with specific processing requirements.  Stabilizer one-packs are available based on lead salts and soaps, but also as calcium-based stabilizers to meet regulatory demands in Europe and other areas of the world. Baerlocher has also developed zinc-free calcium-organic stabilizer one-packs.
