Description
Product overview
D350 is the antimony-free grade within the published ATO-replacement series. Its specific application focus is PVC leather and cable materials, making it a candidate for compounders developing an alternative to an antimony trioxide-containing flame-retardant package.
Applications
- PVC leather and coated-material formulations.
- PVC cable compounds.
- Reformulation of PVC systems with an antimony-free additive requirement.

Formulation and qualification notes
Evaluate D350 with the actual PVC resin, plasticizer, stabilizer and other flame-retardant ingredients. Do not assume a fixed 1:1 substitution or a guaranteed fire rating. Confirm the current compositional declaration and the relevant analytical requirements when an antimony-free specification is part of the purchase criteria. Use in PVC does not make the finished PVC compound halogen-free.
Packaging and storage
Published packaging: 25 kg bags, with 500 kg or 1,000 kg pallet configurations. Store sealed in a cool, dry place away from direct sunlight and moisture.
