Clarifying Agent BT-9803
1. Introduction
Clarifying agent BT-9803 is a high performance sorbitol based clarifying agent that reduces
haze and enhances the clarity of polypropylene through nucleation of the polymer. This also
leads to enhanced stiffness of the molded part and to shorter cycle time during the molding
process. BT-9803 is the 2 nd Generation with improved quality which is ideal for food
contact and medical applications. The structural formula of this product has been
approved by FDA allowable using in food contacts in the world market.
2. Features/Benefits
Clarifying agent BT-9803 is used for producing high clarity polypropylene. The product acts
as a clarifying agent, by creating a large number of small size spherulites (<1μm) during the
cooling of the polypropylene melt. These small spherulites lead to a polypropylene that has
greatly improved clarity and reduces haze compared to polypropylene which is not clarified.
3. Physical Properties
Appearance: White powder Moisture content ≤%: 0.01
Melting Point: 248--255 °C Bulk Density: 120--290kg/m 3 at 20°C
4. Industrial Use
Clarifying agent BT-9803 is high effective clarifying agent for polypropylene homopolymer,
random copolymer. Clarifying agent BT-9803 could be blended with polypropylene powder
though the dry mixing or the master batch and it gives high transparency and improves
mechanical properties, heat resistance. The notified chemical will be applied in thin wall
injection moulding, film sheet extrusion, blow moulding and rotational moulding.
Clarifying agent BT-9803 helped make polypropylene more appealing to consumers and
increased its usefulness through improved transparency. Leading injection molding markets,
the following products can be produced, including housewares, storage cases, living hinge
cases, thin-wall containers and disposable syringes and clarified polypropylene blow molded
bottles for pharmaceuticals, spices, juices, sauces, vitamins, and baby bottles.
The dosage for Homo PP, Random copolymer PP is recommended between 0.2%--0.3%.
5. Packing and Storage
Every 10 kg are packed in one kraft paper bag with PE liner, and single PE bag inside.
