TPEs find a niche in medical PPEs


KRAIBURG TPE, a recognized global leader in superior thermoplastic elastomer (TPE) compounds, offers a range of THERMOLAST® M compounds for personal protective equipment (PPE) applications in the medical sector.

Given the rise of diseases like Covid-19, the role of Personal Protective Equipment (PPE) in protecting the healthcare workforce has never been more important.

PPEs provide protection against cross-infections and pathogenic transmissions and have the potential to block infections originating in blood, body fluids or respiratory secretions.

Due to the levels of exposure risks in hospitals, it is required that PPEs, including disposable surgical masks and gowns, face shields, goggles, glasses, and shoe covers, are safely designed and manufactured. PPEs also have to be durable, comfortable to wear, and to provide adequate barrier against contact with body fluids and respiratory secretions; plus able to withstand the rigors of patient care for healthcare workers and medical front liners.

Innovative materials such as thermoplastic elastomers (TPEs) respond to the functional issues related to PPE designs, owing to their versatility and durability. The advantages of mechanical properties coupled with biocompatibility, make TPEs well-suited for medical applications in parts sealing, strips, handles, and more.

KRAIBURG TPE, a global TPE manufacturer of a wide range of thermoplastic elastomer products and custom solutions for multiple industries, offers custom-made TPE compounds, such as the high-quality custom-engineered THERMOLAST® M materials for medical PPE applications.
 

Medically fit compounds
Due to the use in of the compounds in a critical sector, KRAIBURG TPE’s THERMOLAST® M compounds are produced exclusively on a special medical unit.

The compounds also meet the requirements of the VDI 2017 guideline for medical-grade plastics (MGPs), issued by the Association of German Engineers (VDI), as well as the Reach and RoHS standards and Regulation (EU) No 10/2011, for use in medical applications.

The US DMF-listed compounds also conform to US CFR 21 FDA (raw material conformity), and are certified to ISO 10993-10 (Intracutaneous irritation), ISO 10993-4 (Hemolysis), USP <88> (Biological Reactivity, Class VI), ISO10993-11 (Acute systemic toxicity) and ISO 10993-5 (Cytotoxicity).

Furthermore, most KRAIBURG TPE’s THERMOLAST® M compounds are sterilizable with superheated steam of 121°C or 134°C, γ-gamma ray treatment (2 x 35 kGy), β-ray (electron beam) treatment (2 x 35 kGy) and EtO gas, making them applicable in the medical sector.

In addition to the easy sterilization properties, important features of the THERMOLAST® M compounds are their excellent elasticity and soft, flexible surface.

Targeted at the medical sector, the THERMOLAST® M compounds are free of allergens such as latex, as well as avoid potential environmental pollutants such as polyvinylchloride (PVC), phthalates, and BPA (bisphenol A).

Durability factor of compounds
The THERMOLAST® M series includes the MC/LF compounds that can be applied in breathing masks, goggles, sealing for face shields and handles of glasses to protect users against viral and bacterial contaminants.

Benefits of this series are the hardness level of 30-90 Shore A, low surface friction, abrasion and scratch resistance and the translucent color. Furthermore, the MC/LF series of compounds can be easily processed through injection molding and extrusion, with properties of adhesion to PP.

Meanwhile, the MC/AD/PA compounds in the THERMOLAST® M series are suitable for applications such as face shield head comfort pads and face mask seals that are used to protect users against infectious diseases.

Properties of the injection moldable compound are the hardness level of 60-70 Shore A, and its adhesion with nylons, such as PA6 and PA12. Available in a natural color, it is also easily colorable in effect colors, to allow for customization in medical PPE applications.
