Suitable Applications

ADM-PSZ can be used for anti-mold and antibacterial protection in silicone rubber products such as:

  • Medical devices
  • Daily necessities
  • Children's toys
  • Sports products
  • Kitchen and bathroom products
  • Automotive parts
  • Electrical and electronic components
  • Waterproof seals and gaskets

Key Performance Benefits

  • Low addition level, high efficiency, stable, and long-lasting.
  • Water-insoluble; no water-soluble leaching; excellent wash-out resistance.
  • Free of arsenic, tin, and other heavy metals; complies with EU regulations.
  • Resistant to acid, alkali, UV, and high temperatures up to 280°C.
  • Does not yellow or affect color.
  • Non-leaching treatment — does not migrate, leach, or get consumed by microorganisms.
  • Provides durable surface protection.
  • Compatible with silicone vulcanizing agents, catalysts, and other additives.
  • Physical mode of action — does not lead to microbial resistance.

Recommended Addition Level

The recommended addition level is 1.5–2.5% based on the total weight of the final product. The optimal concentration depends on several factors, including the sensitivity of the system to microbial degradation, the extent of microbial invasion, the type of microorganisms, pH, temperature, humidity, and the required protection period.

Processing & Safety Considerations

  • Store at room temperature, protected from light, sealed, and moisture-proof.
  • Wear protective clothing, rubber gloves, goggles, and a mask during handling.
  • Avoid contact with skin, eyes, and mucous membranes.
  • In case of contact, rinse immediately with plenty of water and seek medical attention if necessary.
  • Acute oral toxicity (rat): LD50 3700 mg/kg — low toxicity.
  • Acute dermal toxicity (rabbit): LD50 3600–3500 mg/kg — low toxicity.
  • Undiluted product is a severe skin irritant; diluted concentration is non-irritating.
  • Undiluted product may cause skin sensitization; diluted concentration shows no sensitization.
  • Rapidly and completely degrades into harmless substances; environmentally harmless.
