High flexibility even in crisis situations

Ahlhorn | 26.05.2020

With the production of visors and respiratory masks, Dr Dietrich Müller GmbH shows a high degree of flexibility in the pandemic.

In addition to visors, sufficient respiratory protection mask production is necessary to ensure protective measures for the own population, medical staff, nursing staff, emergency services and etc. Countries such as South Korea and Taiwan have a significantly low number of confirmed COVID-19 cases. Adequate mask availability and compulsory masking at an early stage are suitable measures to prevent the rapid spread of pathogens such as COVID-19.

The mucous membranes of the eyes, nose and mouth are potential entry points for pathogens into a body that are transmitted by droplet infection. The use of respirators can reduce the likelihood of droplet infection in close contact by preventing liquid particles from reaching the mucous membranes and airways of other people when breathing, talking, sneezing or coughing. In addition, respiratory masks protect staff from splashes of body secretions, contaminated liquids and touching the mouth and nose with contaminated hands.

Filtering half masks consist of several layers of nonwovens, elastic bands and a malleable nosepiece. The basic material for the masks are plastic granulates, which are melted using so-called meltblow systems. By varying process parameters such as material, temperature, pressure, binding agent, water and mechanical disruptive bodies, different types of nonwovens can be produced and optimized for the given application. Various types of nonwovens are used to manufacture FFP2 masks and mouth-nose protective masks for operations (MNS OP). The mask structure for MNS OP is primarily made up of three layers. The two outer layers are made from spunbond and are identical. The inner layer consists of meltblown fleece. Additional layers of meltblown fleece are incorporated into FFP2 masks to increase safety.

The Dr. Dietrich Müller GmbH has a lot of experience in the processing of nonwovens, so that production could be expanded to include the manufacture of respiratory masks in a short time.

The Dr. Dietrich Müller from. This is also reflected in the manufacture of electrical insulation materials, heat-conducting products, seals and technical foils. The company’s product portfolio includes flexible electrical insulation materials, prepregs, 3D printing, coated fabrics, adhesive tapes, laminates and profiles, heat-conducting products, technical films, sealing materials, mica products and other product groups.
