Our Prem-o-clave® material is made of polyvinyl chloride, which is waterproof, non-allergenic, and bacteria and stain resistant. Our Soft-o-clave® material is made of a soft, fabric-like polypropylene, flame resistant, water resistant, non-allergenic, and bacteria and stain resistant. All our materials can be machine washed and dried at cool settings.
*Please note: Our Prem‑o‑clave® material no longer contains fire‑retardant additives.
Fire retardants commonly rely on antimony compounds, a critical mineral used widely in flame‑resistant plastics and textiles. Antimony supply is heavily concentrated in China, which controls roughly 80–90% of global refining capacity and a dominant share of production. [goldinvest.de] [markets.bu...nsider.com]
Beginning in late 2024 and continuing through 2025, China implemented export controls and restrictions on antimony, including limits affecting U.S. supply, contributing to significant global shortages, in retaliation of the U.S. tariffs. These constraints disrupted supply chains and drove sharp price increases across industries that rely on flame‑retardant materials. [habtoorresources.com], [pricepedia.it] [complordfl...ardant.com]
As a result, the cost of antimony‑based materials increased substantially, with downstream products experiencing significant price pressure. Postcraft is not able to absorb these increases, and our customers have not been willing to accept the higher pricing.
Therefore, Postcraft has made the decision to remove antimony‑based fire retardants from our vinyl products for the foreseeable future.
