Feature

BX NA 11 is the second generation of aryl phosphate type stiffening and transparent nucleating agent that is applicable to the crystalline polymer. It is characterized by a high melting point, outstanding thermal stability, and strong nucleating ability, and its effects are very remarkable in improving the transparency, stiffness, tensile strength, and creep resistance of products. It applies to all kinds of modified polypropylene products. It’s free of aldehyde odor, precipitation and discoloration. The significant effect of BX NA 11 is that it can improve stiffness/rigidity.

Specification

Appearance: White powder.
Moisture (%): ≤ 1.0
Melting point (℃): ≥400 (DSC Test Method)

Application

BX NA 11 nucleating agent is mainly used in the homo polypropylene and polypropylene random copolymers, such as the production of modified polypropylene products with high crystallinity, high stiffness, and high heat resistance. The product mainly applies to the production of polypropylene products, for example, car bumper, internal trim panels of the car, instrument panels, and shells of small appliances (electric iron, hair drier, electric cookers, and electric saucepans).
As a clarifying agent, BX NA 11 is mainly used in the polypropylene random copolymer, such as the production of transparent modified polypropylene products. It can improve stiffness while improving transparency. The product mainly applies to the production of medical devices such as disposable infusion sets, disposable injectors, and disposable syringes as well as food containers.

Suggested dosage level of 0.2-0.3%, Dry blend for at least 10 minutes (the speed at 1000 RPM) to make sure even distribution. In order to improve the product’s dispersity in the resin, the methanol or ethanol solution is often mixed into the resin.

Handling and storage

BX NA 11 shall be stocked In a ventilated and dry environment, the shelf life is two years. 20 kg/ bag. Conditions of transport for non-hazardous products.
