Blades to Cut Latex, Silicone, TPE, ETFE, PTFE [Customer Case]

latex tubing for medical use - sollexIn this article we will look at a case study of a manufacturer who had a problem with cutting latex tubes for medical application and asked Sollex for a blade that would give a clean cut.


Latex Elastic Material in Medical and Healthcare

Latex material is known for its exceptional elasticity, which allows it to be stretched and then return to its original shape without permanent deformation. In the medical field, latex is used in various applications such as surgical tubings, elastic bandages, surgical drains, and in some types of catheters. It also has good resistance to acids, alkalis, and other chemicals.

There are several other soft elastic materials that have properties similar to latex and can be used to make medical tubing: silicone tubing, thermoplastic tubing, ETFE tubing, PTFE tubing, polyamide, polycarbonate, polyethylene, polyimide, polyolefin, polypropylene, polyvinyl chloride, thermoplastic elastomer tubing, nylon tubing, non-latex tubing.

Latex tubing, made from natural rubber latex, is a highly stretchable and elastic material widely used in various medical and non-medical applications.

Cut Latex and Other Elastic Materials like TPE, EFTE, PTFE, Silicone, Nylon

Cutting latex, particularly in the form of thin sheets or tubing, can be challenging. Latex is highly elastic and tends to stretch rather than cut cleanly. When you apply a cutting force, the elastic material stretches away from the blade or cutting tool instead of being sliced through. The material bends and twists which makes exiting the material trickier and a clean cut almost impossible.

Latex Tubing Cutting Test [Customer Case]

On behalf of our client, we conducted experiments to cut thin latex surgical tubes and to find the best blade for cutting elastic tubing with a clean cut. And these are the conclusions we reached as a result of the experiment and the challenges we faced.smooth cut and uneven cut when cutting latex tube 0.5mm - sollex

4 Challenges When Cutting Stretchy Materials such as Latex

  1. Normal blades are either too thick and blunt or too thin and flexible. The thick blunt blade presses through leaving a not so clean cut and a material tail. Too thin blades slides on the stretchy material.
  2. The sharpness and type of the cutting tool play a significant role. Dull blades will struggle to cut through latex cleanly and are more likely to pull or tear the material. A very sharp, thin blade is typically required for a clean cut.
  3. The thickness of the latex and its uniformity can also impact how easily it can be cut. Thinner latex may be more prone to tearing or stretching, while thicker latex requires more force to cut through, which can be difficult to control precisely.
  4. The technique used to cut latex is also important. It often requires a steady, controlled motion with consistent pressure. Any variation in the cutting motion can lead to jagged edges or tearing.

3 Cutting Techniques for Cutting Thin Latex or Elastic Polymer Materials

When cutting thin latex or very resilient soft polymer materials, there are 3 things we have found to work well.

Latex tubing when cut - example - sollex

  1. Use reinforced single edge razor blade, double sided, triple bevel blades, 62G
  2. Use single sided double bevel blades
  3. Cutting material through a column with a thin razor blade

First thing first, fixing the material is imperative for any type of soft material cutting. Leading the material in a drilled hole or die is strongly recommended.

Three other things are extra important when cutting elastic materials like latex. The blade needs to be kept straight. It needs to be pretty thin. Finally and most important, the edge needs to be extra sharp. Keeping the blade straight can be done by reinforcing its back-side or letting the slitting blade cut through a column that keeps the blade straight at all times.

Industrial Blades to Cut Elastic Materials

As a result of the tests, Sollex was able to find a blade that met the specified requirements. The customer from the medical industry, a manufacturer of latex tubing and products, also adapted the recommendations on cutting techniques and easily put them into practice. The company was very satisfied with the result and the clean cut they now get on their latex products.

If you are also looking for an industrial blade for cutting latex or other elastic materials for the production of catheters, tubes and other medical products - contact Sollex, we will help you.
