Technical Information

Here you will find all important information for the physical properties of the different tube materials. Furthermore, you will receive information on the attributes and possible certification. A detailed description of the standards and norms as well as the conversion table can be found in the right column of this page.

Standards & Norms

Food Suitable

The materials, which are summed up under the term food suitable, correspond to the regulations of the FDA and/or the European regulations EC 1935/2004.
A lot of our tubes are available with certificates, which comply with the food regulations under EC-law or the FDA (U.S. Food and Drug Administration).
The FDA is the regulatory agency of the United States of America for monitoring of food and approval of drugs. The FDA monitors the safety and effectiveness of human and animal medicines, biological products, medical products, food suitable and radiation-emitting devices. This applies to both products produced in the USA and to imported products.
The EC 1935/2004 defines uniform laws in reference to packaging materials and objects, which will come into contact directly or indirectly with food. The regulations are supposed to protect human health as well as consumer interests and guarantee that the products can be sold all over Europe.

USP Class VI

The marked tube materials are all available with certificates that meet the guidelines of the USP Class VI (pharmaceutical approval).
The U.S. Pharmacopeial Convention (USP) is a non-commercial organisation that develops the standards for the quality of medications and other medical products. These include tests for biological responsiveness of elastomers, plastics and polymers with direct or indirect patient contact. The standards are divided into six classes. Class VI includes the strictest tests and is widely used and accepted in the pharmaceutical and medical products industry.

ADI Free

Our ADI-free (Animal Derived Ingredients-free) marked tubes do not contain any raw materials of animal origin (e.g. tallow derivatives such as glycerin, fatty acids etc.). The consequence is that the particularly resistant BSE/TSE virus can be excluded 100% in the products and thus will not enter the production equipment of food producers. The use of these tubes thereby deliver maximum process security.

Without Phthalate

Phthalates are used as plasticizers for polymers. They help to improve softness, stretchability and better handling. They are chemically not firmly tied and evaporate slowly but permanently out of the products. Only an abandonment of phthalates can guarantee that these substances do not end up in the process. Marked products of emtechnik are 100% free of phthalates.

Electrically Conductive

To avoid a static charge of the tube, the high-performance material PTFE-EL is equipped with electrically conductive particles. The addition of 2,5% carbon gives it a very low surface resistance of <106Ω; This makes it suitable for use in hazardous areas. For all media that are sensitive to UV radiation PTFE-EL is dyed a solid black and therefore making it UV-resistant.


The tubes of emtechnik are resistance to aggressive media and in aggressive area.
