Product advantages:
1.The quality standard has been tested by SGS to meet international Environmental protection
standards.
2. High stability: The thermal stability of this product higher than that of lead-based.
3. High transparency: It has the same light transmission mechanism as PVC.
4. High insulation: By reacting with anion exchange, the absorbed chloride will not be released,
and the insulation is excellent.
5.High safety: After testing, hydrotalcite can be used in food packaging bags made of polymer
materials.
6. No vulcanization pollution, can be used in conjunction with various heat stabilizers.
Application areas:
1.The product is mainly used as a non-toxic and halogen-free flame retardant for
synthetic materials.
2.It can be used as slow-release moisturizing in agricultural film, which can produce
greenhouse film with high light transmittance, low haze and good moisturizing property.
3.It can be used as a multifunctional filling improver for flame retardant, stable,
insulating, coloring, anti-ultraviolet, etc. for polymer materials such as plastics, rubber, and
chemical fibers.
4.It can be used as daily chemical raw materials such as dyes, coatings, paints,
cosmetics, etc., as a flocculant for water purification of dye fabric wastewater treatment.
Packaging/Storage:
1. This product is packed in woven bags with inner plastic and outer, each bag is 20kg.
2. It should be stored in a ventilated, dry and cool place, protected from moisture, high
temperature, and not in contact with acids and alkalis.
