Materials used for pharmaceutical packaging and personal protective equipment (PPE) must possess qualities such as strength, clarity, and breakage resistance. Transparent polyvinyl chloride (PVC) resin is highly regarded in various applications due to its exceptional clarity, chemical resistance, and ease of processing. Nevertheless, the brittleness of this resin at room temperature and low temperatures may restrict its use in demanding pharmaceutical settings. DOW PARALOID™ MBS impact modifiers have become a crucial solution in improving the performance and dependability of transparent PVC.
The Role Of Impact Modifiers
Impact modifiers are essential in modifying the mechanical properties of PVC resin, particularly in enhancing its toughness and impact resistance without compromising transparency. These additives create a more energy-dissipative matrix within the PVC structure, allowing it to absorb and dissipate impact forces more effectively.
Why DOW Paraloid™ MBS Impact Modifiers?
1. Contributes To Toughness and Durability
DOW PARALOID™ MBS impact modifiers significantly improve the impact strength of PVC resin. This is crucial for pharmaceutical packaging, which often undergoes mechanical stresses during production, transportation, and end use.
2. Maintained Optical Clarity
One of the standout features of DOW PARALOID™ MBS additives is their ability to enhance toughness without compromising the optical clarity of PVC. This is particularly important for pharmaceutical applications where product visibility and aesthetics are critical.
3. Chemical Resistance
Pharmaceutical packaging materials must resist various chemicals and solvents. PARALOID™ additives maintain the inherent chemical resistance of PVC, ensuring the integrity and safety of the packaged products.
4. Low Temperature Performance
Packaging materials often need to withstand low temperatures during storage and transportation. Impact additives enhance the low-temperature impact performance of PVC, ensuring that the packaging remains robust and intact, even in cold environments.
5. Processing Efficiency
These impact modifiers are designed to integrate seamlessly into standard PVC processing methods. They offer excellent compatibility with PVC and other additives, resulting in efficient manufacturing processes and consistent product quality.
Applications in Pharmaceutical
DOW PARALOID™ MBS impact modifiers can be used in several critical applications for transparent PVC in pharmaceutical packaging:
Blister Packaging
Blister packs require high clarity for product visibility and tamper evidence. PARALOID™ provides enhanced toughness that ensures blister packs are durable and protective.
PPE
Medical PPE, such as partitions, face shields, and technical films, are often made of transparent PVC, which benefits from the enhanced impact resistance and protects sensitive equipment during shipping and handling.

In conclusion, DOW PARALOID™ impact modifiers represent a significant advancement in the field of transparent PVC materials for pharmaceutical packaging. Their ability to enhance impact resistance, maintain optical clarity, and ensure chemical resistance underpins their essential role in developing robust, safe, and reliable packaging solutions. As the pharmaceutical industry continues to demand high-performance materials, integrating PARALOID™ will remain crucial in meeting these evolving needs.
