PEI resin blend with enhanced hydrolytic stability


Evolving global regulations and growing numbers of patients seeking high quality care are driving the healthcare industry to continuously look for new ways to enhance safety throughout the industry value chain. Sabic offers a portfolio of engineered thermoplastics and polymer technologies that claim to help enhance the safety for care-givers and patients.

To help enhance patient and clinician safety in healthcare environments, Sabic is committed to helping reduce Healthcare Associated Infections (HCAIs). According to the World Health Organisation, of every 100 hospitalised patients at any given time, seven in developed countries and 10 in developing countries will acquire at least one HCAI. Sabic has responded to this challenge with a range of LNP antimicrobial thermoplastic compounds, using silver-based antimicrobial technology, as silver is well-suited to diverse applications and accepted as a broad-spectrum antimicrobial, with activity against multiple pathogens. With four different base resins and two different levels of antimicrobial effect, the company offers a broad portfolio of antimicrobial materials, which are said to meet the strict requirements of the healthcare industry, while helping to enable the prevention of HCAIs. Sabic’s customisation capabilities have resulted in a myriad of potential antimicrobial solutions which include fluid and drug delivery applications, surgical instruments, monitoring and imaging devices and durable medical equipment such as hospital beds and operating tables.

A recent collaboration with Indusbello resulted in a differentiated solution for sterilisation trays using Sabic’s Ultem HU1004 resin, a polyetherimide (PEI) resin blend with enhanced hydrolytic stability. This technology is designed to withstand a number of harsh sterilisation processes, including hydrogen peroxide, required in cleaning medical devices to help reduce infections, while providing flexibility in design, transparency, good aesthetics and enhanced productivity through injection moulding.


Healthcare packaging solutions

The healthcare packaging industry has an increasing demand for safe and high performing flexible material for packaging pharmaceuticals and medical products. The pouches and sachets – made out of this material – should not only preserve the packaged medicine but should also ensure safe use by the patient.

Sabic’s latest film range responds to this rising market need. This new range includes Sabic HDPE PCG5009, Sabic LLDPE PCG0863F and Sabic LLDPE PCG6118NE. They are said to help optimise the seal and package integrity which then results in an optimised preservation of medicines and an improved safety of medicine usage. These grades are fully tested in accordance with the relevant European Pharmacopoeia (EP) and United States Pharmacopoeia (USP) requirements to meet the needs in the pharmaceutical industry for high quality and safety for their packaged drug products during shelf-life.

Drug transfer applications

Within the healthcare profession, there is an increased demand for techniques to improve the accuracy, efficiency and precision in drug transfer. Sabic PP PCGR40 and Sabic PP PCGR40L are the company’s latest solutions within its polymer portfolio. This clarified polypropylene (PP) material has, by the company’s own account, an exceptional glass-like clarity that supports improvements in dosing accuracy and better detection of contaminants in medical applications such as conventional or pre-filled plastic syringes and dosing systems. The grade is produced with a peroxide-free technology which results in a cleaner resin as no peroxide residues will migrate into the medicine from the syringe barrel. Ultimately, this is said to result in a better preservation of drug contents during shelf-life in primary packaging for pharmaceutical products or medicines. These grades can be gamma sterilisable to respond to an increasing need for advanced packaging such as preservative-free packaging and dispensing devices which reduce the patient’s adverse reaction to preserved formulations while preventing contamination and degradation of the medicine.
