Advantages of Shatterproof Lamps and FEP Lamp Coatings

Advantages of Shatterproof Lamps and FEP Lamp Coatings

At Adtech, we specialise in applying fluoroplastics as a protective barrier, which means that more volatile and delicate materials such as glass can be safely used in a wide variety of settings without fear of contamination or shattering. No better example is our use of FEP in coating glass lamps to make them more durable, resilient and shatterproof.

Adtech is a pioneer in shatterproof lamp technology, and in fact, we were the very first company in Europe to apply FEP lamp coatings to glass in this way and to carry out testing on the UV transmission of FEP.

Being a fluoroplastic, FEP is an excellent material, being non-stick, strong and sturdy, able to withstand high temperatures, and completely unaffected by UV light. When FEP is applied as a barrier layer to glass lamps to make them shatterproof, this means that they can then be safely used in many different environments. FEP protects the integrity of the lamps and the environment that they are situated in, and literally lets nothing through, making the glass truly shatterproof.

Bonding Fluoroplastics to Other Surfaces Using Chemical Etching

Bonding Fluoroplastics to Other Surfaces Using Chemical Etching

Fluoropolymers, invaluable for their versatility and consistency, are celebrated for their non-stick qualities. However, this creates a problem if you need to bond a fluoroplastic component to another surface.

Fortunately, Adtech have devised a solution to this problem using a process called chemical etching.

How does Chemical Etching work?

Chemical etching is very useful in that it allows the intrinsic qualities of fluoroplastic products (such as heat resistance and a non-stick texture) to be maintained.

Very cleverly, fluoroplastic etching works by stripping the fluorine molecules from the carbon backbone of the fluoropolymer, leaving a deficiency of electrons around the carbon atom. Exposure to air, hydrogen, oxygen molecules and water vapour then allows the electrons surrounding the carbon atom to be restored, resulting in a group of new organic molecules which allow successful adhesion to take place. Once bonded, the etched material will then be brown in colour (although the shade varies depending on the exact material used).

Formed PTFE Sheets

Formed PTFE Sheets

As the leading stockists and manufacturers of high-performance fluoroplastics, here at Adtech we are constantly striving to develop new and exciting products for our customers. PTFE sheets are one of our most recent developments, and, like our specialist fluoroplastic tubes and rods, they are highly effective in a variety of business scenarios.

Originally developed for use in aerospace applications, PTFE is suitable for use in a number of industrial applications. Withstanding temperatures of -200ºC up to +260ºC whilst retaining most of its properties, PTFE is the most thermally-stable plastic. Its high melting temperature makes it the ideal substitute for other weaker plastics that have a lower melting point and are typically used for low-cost applications.

PTFE is also the lowest friction fluoroplastic, with fantastic anti-adhesive and sliding properties – so much so that it is the only known material that a gecko cannot stick to!

Alongside this, PTFE is chemical, UV and acid resistant, making our PTFE sheets an excellent purchase, able to endure even the harshest of environments.

The benefits of vacuum forming for your business

The benefits of vacuum forming for your business

At Adtech, we look to deliver the best solutions to suit each clients’ specific needs. When it comes to the manufacturing of plastic products, we recommend vacuum forming as a go-to manufacturing process for the majority of plastic production.

What Does Vacuum Forming Involve?

Vacuum forming is a type of thermoforming process by which fluoroplastics are moulded into specific shapes. Vacuum-formed products are used in our daily lives, and often in places we don’t even realise, from yogurt pots to bath tubs, fridge liners to sandwich boxes, the process can be used to make fluoropolymers into all kinds of complex shapes and designs.

With vacuum forming, in order to produce a certain shape, plastic is heated until soft, draped over an already-formed mould, and then ejected and left to become solid –whereupon the new form is maintained.

As the pressures which are applied to the plastic during production are very low, vacuum-formed products can be made from several fluoroplastic materials including FEP, Tedlar PVF and PVDF. Also, because the fabrication process itself is very quick, this makes vacuum-forming ideal for repeat and high quantity orders, while the moulds themselves also have extended lifetimes when compared to other moulding processes.

Vacuum Forming for Low Cost Manufacturing

Since vacuum forming is a particularly simple form of thermoforming, the cost of the manufacturing process is significantly lower than with injection moulding methods. The production process is straightforward, the machinery is less costly, and the fluoroplastic materials themselves are also available at low cost. This means that operational expenses can be kept low, while the products themselves can be produced at an extremely high structural standard, making it a process popular with many.

Using HF Welding for a Stronger Join

Using HF Welding for a Stronger Join

What is HF Welding?

High Frequency welding, or HF welding, is a method of joining plastic materials together using an electromagnetic field coupled with pressure to create a tight seal.

In the HF welding process, electrical energy causes the molecules within the material to move around, generating heat and softening the PVC and PU material so that it begins to fuse together – similarly to the regular lamination process. Once cooled, the HF-welded surfaces become completely fused together, creating an extremely strong join.

This secure bonding creates an airtight environment, providing low permeation of other gases into the bag, and enabling the sample to remain uncontaminated.

Sampling Bags

At Adtech, we use HF welding to produce PVC and Polyurethane (PU)  air sampling and liquid bags for clients on a regular basis, which are vital for protecting critical environments from contamination.

PVC and PU general-purpose sampling bags are quick and easy to produce, extremely durable, and widely used for non-critical testing as a cheaper alternative to more expensive materials, such as FEPTedlar and PVDF.

FEP Roll Covers for the Printing Industry

FEP Roll Covers for the Printing Industry

At Adtech, we specialise in producing FEP heat shrinkable roll covers for the printing industry, to eliminate problems with sticky build-up on the rollers.

Our roll covers are used by a wide variety of different printers, including a pioneering recycling company who are able to recycle disposable coffee cups.

The fluoroplastic qualities of FEP mean that the roll covers are naturally non-stick, resistant to chemicals and corrosion, and the longevity of our FEP roll covers is also excellent, being suitable for long-term use in both hot and cold environments with minimal long-term deterioration.

In contrast to a sprayed-on PTFE roller coating of 0.005mm in thickness, FEP roll covers are typically a much more sturdy and durable 0.5mm – so they work much more efficiently for the same price. For extremely high temperature applications, such as for laminating paper to polyethylene and extrusions, we also produce PFA roll covers, which have a flex life of ten times the FEP roll covers and can withstand temperatures of up to 250°C (as opposed to 200°C with FEP). Whatever your needs, we make PFA and FEP roll covers to order.

Why Fluoroplastics such as PTFE, FEP and PFA make ideal Heat Shrink Materials

Why Fluoroplastics such as PTFE, FEP and PFA make ideal Heat Shrink Materials

Fluoroplastics can be moulded into any shape or consistency that a project requires. While Adtech is known for producing specialist fluoroplastic tubing, we also produce many different fluoroplastic heat shrink materials for a wide array of industries.

Fluoroplastic heat shrink is a very effective way to cover and encapsulate devices to make them non-stick and electrically inert. As these materials can withstand high temperatures, chemicals, solvents and UV light, they are ideally suited for use in harsh environments, for example, as temperature sensors, probe covers, battery pack assemblies, for encapsulating medical devices, creating automotive components and shatterproof lamps

For the electronics industry, fluoroplastic heat shrinkable sleeves are ideal for insulating connections in hot environments such as toasters, kettles and soldering irons. Meanwhile in the medical industry, Adtech’s PTFE and FEP heat shrink sleeving is widely used by manufacturers of medical devices.

It can be produced from FDA and USP Class VI compliant raw polymers and we also offer full traceability for materials supplied for all medical applications. (A major advantage of using fluoroplastic heat shrink wrap or sleeving for medical devices is that the materials are inert, non-toxic and bio-compatible. Being non-stick, they also offer low co-efficient friction, meaning that coated parts can easily slide inside other parts – perfect for intricate medical assemblies.)
