Diaphragms and sealings are complex in structure and have to meet the most difficult applications. They not only have to be resistant to aggressive chemicals, oils and fats, but also have to have very good dynamical and mechanical properties. Good product longevity by a constant usage should be guaranteed. So, PTO offers polyester, polyamide and aramid fabrics (Kevlar or Nomex) coated on one or both sides either cured or uncured. For the production of elastomer coated diaphragm cloths many different kinds of rubber such as NBR, CR, CS, CSM or EPDM as well as high performance materials like HNBR, XNBR, ECO, FKM or silicone rubber are used. You can find diaphragms and sealings made of elastomer coated fabrics produced by PTO not only in fuel injection pumps and gasoline tanks of well-known car manufacturer, but also in the measurement and control technology that works with hydraulic liquids of great plants or chemical companies.

Nowadays the market offers many kinds of canvas fabrics. PTO has dealt for many years with this product and can offer a great variety of canvas fabrics. Therefore, high tensile polyester or polyamide fabrics are coated with all accessible elastomers. If you need a high chemical or oil resistance NBR, CR, HNBR, NBR, ECO or FKM are used. Do you wish to have a good weather resistance and brilliant colours? Then EPDM and CSM are applied. A good alternative solution for the low-temperature range would be NR. Very good burning characteristics of our canvas fabrics are also a matter of course as well as good product longevity. So, our canvas fabrics can be used for different industrial applications.

Folding bellow cloths produced by PTO are worldwide employed as flexible gangway systems for busses, trams, high speed trains, undergrounds and at airports. No matter what country Germany, France, China or India, folding bellow cloths have to meet the highest requirements everywhere. Vehicles are getting faster and faster and demand fabrics with very good dynamical and mechanical properties that fulfill these new requirements. A good fire resistance, a low smoke gas density, a high resistance to UV, climate and abrasion as well as brilliant colours and product longevity are needed, too. Also very important is a good workability at our customers´ what PTO is known for worldwide.

From the very first day, apron cloths count to the standard range of PTO. Our company has produced these products for 15 years now. In these years, our employees have constantly worked on improving apron cloths, which has always been appreciated by our long-standing customers.

As a result, we can now deliver snow white apron cloths which have an excellent resistance to animal oils and fats as it is demanded in the processing industry. Apron cloths are also available in cream white, orange, blue, reddish brown, black and in any other colour. Our elastomer coated apron cloths, which are rubberized on both sides and have a fabric or knitted fabric lining, are high tensile, permanent flexible, waterproof, very comfortable and feel nice to the touch even after having them washed many times. That is why PTO´s apron cloths have proven their worth Europe-wide in different kinds of application areas, e. g. in the processing and in the technical industry. Customized lengths, widths and thicknesses are a matter of course.

Your requirements profile for our product includes high resistance to aging, ozone, weather, and temperature. Do you require consistently good chemical resistance over the entire temperature range? Do you have a safety component that has to meet a wide range of fire requirements, or does your product need to be certified for the food industry? Silicone meets this requirement profile.

Thus bellows, turbocharger hoses, conveyor belts in the food industry, seals for medical technology, aircraft construction, and electronics are just a few examples of this diverse material's application. Its operating temperature range lies between -60 °C and 200 °C. Higher thermal stress limits are possible with the use of special silicones such as fluorosilicone.

We're independent and can act quickly due to our capabilities.We process liquid and solid silicone in a wide variety of colour matchings. Achieve compliance for FDA/BfR approval or in relation to a wide variety of fire requirements. We'll also gladly provide you a pilot plant sample with reinforcing materials.

Furthermore, we develop and produce individual silicone profiles to the most varied specifications drawn up by our customers, which we can also then print onto. We develop profiles for the most diverse demands, regardless of the size, shape or colour, complicated cross-section, large scale or fine detail. Difficult geometries, contactless vulcanisation and the achievement of a particularly high surface quality are standards for us. Small quantities or batches of a few metres are also not a hindrance.

Choose the high-performance material silicone. Choose PTO. We know what it takes. We stand for precision in silicone.
