Hydrotalcites (ALCAMIZER ™) are used in PVC vinyl records to stabilize the polymer during high-heat pressing and long-term use. Hydrotalcites neutralize degradation by-products, keeping the grooves sharp and durable. ALCAMIZER™ (hydrotalcites) replace toxic heavy-metal stabilizers, and ensure the record stays playable and of high quality over decades.

PVC by itself is not stable when processed or when used long-term. The polymer tends to degrade under heat, pressure, or light, releasing HCl gas that causes discoloration, brittleness, and poor performance. Vinyl records need precise groove definition and long-lasting durability, so stabilizers are critical.

ALCAMIZER™ (hydrotalcites) products are used in vinyl records mainly because, the heat of pressing record pressing involves high temperature and pressures (150–180 °C). PVC would start decomposing, but ALCAMIZER™ products trap and neutralize HCl released during heating. This prevents chain scission and keeps the polymer strong and flexible.

Preservation of Sound Quality, Groove fidelity is everything in records. If PVC degrades or discolors during pressing, it can lead to surface noise, distortion, or weaker grooves. ALCAMIZER™ products keep the vinyl formulation stable, ensuring a clean, precise groove pattern.

Replacement for Toxic Stabilizers. Historically, lead- and cadmium-based stabilizers were used in PVC formulations, even in records. ALCAMIZER™ products offer an eco-friendly, non-toxic alternative, aligning with modern regulations (RoHS, REACH) and consumer safety.
