Properties and Usage:
Dibenzoylmethane, as an efficient β-diketone structural heat stabilizer, has become an indispensable additive in PVC and ABS resins. It is mainly used to improve the thermal stability and transparency of PVC products, especially suitable for food packaging and medical supplies, such as mineral water bottles, transparent sheets and films, etc.
Main features:
1. High transmittance: Optimize the transparency of PVC products, especially suitable for applications requiring high transparency.
2. Non-toxic and odorless: complies with strict standards for food safety and medical supplies, and is suitable for use on sensitive items.
3. Synergistic effect: When combined with main stabilizers such as Ca/Zn and Ba/Zn, it can significantly improve the initial and long-term thermal stability of the product.
4. Resistance to "zinc burn": Effectively prevent "zinc burn" phenomenon during processing, effectively prevent the product from being colored in the early stage of use, suitable for hard, non-toxic, tasteless plastic processing fields.
Application scope:
1. Food and medical packaging: widely used to make non-toxic and transparent PVC bottles, sheets, films, etc.
2. Daily cosmetics: Due to its excellent ultraviolet absorption properties, it is also used to make sunscreen and skin cream to protect the skin from ultraviolet damage.
Packaging specifications:
25kgs Carton inner with PE bag;Various specifications of packaging are available
