Key Properties of Borouge BD950MO PP for Bottle Caps Production

Excellent stiffness and impact balance

Borouge BD950MO is a heterophasic PP copolymer. This structure delivers an optimal balance of stiffness and impact resistance, which is essential for bottle caps. With a tensile modulus of 1500 MPa, the material provides superior rigidity, ensuring that caps maintain their shape during stacking, transportation, and screw-on/screw-off cycles. At the same time, its excellent impact resistance prevents cracking or breakage, even in cold storage or rough handling conditions.

Low stress whitening tendency

Borouge BD950MO features an extremely low tendency for stress whitening, ensuring that closures and caps retain their clean, professional appearance even after repeated use.

Superior processability for high-Speed production

Borouge BD950MO is optimized for high-speed injection molding to meet large-scale caps and closures production demands. With a MFR of 7.0 g/10min, the material offers excellent flowability, allowing for fast filling of thin-walled cap molds while maintaining high melt strength to prevent collapsing or warping.

Optimized additives for enhanced performance

Borouge BD950MO PP is formulated with slip and anti-static additives to ensure good demoulding properties, which further enhance its suitability for bottle caps production. Meanwhile, it has excellent dimensional consistency with different colour additives.

What Are Main Applications of Borouge BD950MO PP Granular?

Water and beverage bottle caps

The material is widely used for caps on mineral water bottles, CSD bottles, beveragesn bottles. For CSD bottle caps, its excellent creep resistance ensures that the threaded structure remains intact, preventing carbon dioxide leakage and maintaining a tight seal. For water and beverage bottle caps, its low
hydrophilicity and food-grade safety make it ideal for preserving the purity and taste of the beverage.

Food packaging caps

Borouge PP BD950MO is suitable for caps on edible oil bottles, seasoning jars, and microwaveable food containers. Its resistance to oils and weak acids ensures that the cap maintains its integrity, even when in long-term contact with these substances.

Industrial and personal care bottle caps

Its chemical resistance and durability make it suitable for use with a wide range of industrial and personal care bottle caps. In addition, its processability allows for the production of custom cap designs, including flip-top and child-resistant caps.

FAQs About Borouge BD950MO PP

1. Does Borouge BD950MO PP comply with food contact regulations?

Absolutely. Borouge BD950MO is fully compliant with global food contact standards, including FDA and EU 10/2011 regulations. It is odorless, non-toxic, and does not impart any taste or odor to food or beverages, making it safe for use in all food-contact bottle cap applications.

2. Can Borouge BD950MO PP be colored for custom bottle cap designs?

Yes. One of the key advantages of Borouge BD950MO is its excellent dimensional consistency even when using different colorants. The Borstar® Nucleation Technology ensures that the material maintains its properties and appearance regardless of the color additive, allowing manufacturers to create custom-colored caps that align with their brand identity.

3. Is Borouge BD950MO PP granule recyclable?

Yes, it is fully recyclable. It can be reground, reprocessed and reused in appropriate PP applications without significant property loss if kept clean. Its low dust attraction and good thermal stability support easy recycling in typical PP waste streams.

4. Does BD950MO PP resist chemicals and oils?

Yes, BD950MO has good resistance to oils, fats, weak acids and common household chemicals. This makes it suitable for caps on edible oils, sauces, vinegar, lotions and detergents. It does not degrade or swell easily under normal food and cosmetic contact conditions, supporting long-term package integrity.

5. How does BD950MO perform at low temperatures?

BD950MO PP is a heterophasic copolymer with good low-temperature toughness. It typically provides 4.0 kJ/m² impact resistance at -20℃, so caps resist cracking in cold storage, winter transport or freezer conditions.
