Ever Wondered How Hazardous Chemicals Are Transported?

Rubber for road chemical transportation

When it comes to the transportation of chemical products, ensuring the safety of your products and the people working with them is a priority. In this industry, durable rubber sealing solutions are paramount.

The rubber products must be rigorously tested and proven to ensure complete safety. As such, experts have created the most chemically resistant rubber products possible. These include:

* Discharge valves seals

* Pump seals

* Man lid and access hatch seals

* O rings

* Bonded PTFE seals

Materials for chemical transportation seals

There are a multitude of materials proven to withstand the challenges of the road chemical transportation industry, including FFKM (Perfluoroelastomer), FKM (Fluoroelastomer) and PTFE. Rubber products used in this industry must be highly chemically resistant but also perform in extreme temperature ranges.

PTFE is known for its hygienic properties, but for chemical transportation, one of the essential aspects of this material is its ability to be easily cleaned. This is especially important for the transportation of chemicals, as it reduces the risk of contamination from one cargo to another and allows seals to be reused, providing a cost-effective solution. As a result, PTFE / rubber bonded seals are a popular choice for the road chemical transportation industry.

Another high performing polymer for this particular industry is Perfluoroelastomer (FFKM). A fundamental requirement of the road chemical transportation industry is chemically resistant rubber sealing. Most FFKM materials have been thoroughly tested and proven in service to offer resistance to a huge variety of chemicals. They can also work in low temperature (-40°c) and high temperature (316°c) materials to function at extreme temperatures.

More about FKKM

FFKM O-rings offer exceptional chemical and thermal resistance. They combine the sealing force, resistance and recovery characteristics of a regular elastomer O-ring with the added chemical resistance of PTFE. The Carbon-Fluorine bonds of FFKM, regarded as the strongest single bond in organic chemistry, guarantee the high chemical, thermal and oxidation resistance of our finished O-ring products.

An increase in fluorine content increases the chemical resistance of hydrocarbons. As such, FFKM contains 72.5% fluorine with a fully fluorinated backbone chain, which is the maximum fluorination possible whilst still retaining the elastomeric properties required for sealing systems. FFKM’s ether group (R-O-R) gives it its elastomeric properties and elasticity, without which FFKM would act much the same as PTFE.
