Fire Retardant Plastic Materials

Fire Retardant Plastic Materials Machined @ Sentinel

What are Fire Retardant Plastic Materials

Importantly, some engineering plastics, but more so Industrial insulation plastics, can be classified as ‘FR’. Or, fire retardant plastic materials and, flame resistant plastic. Certainly, no plastic exists that is completely a ‘fireproof plastic material’. Moreover, some plastics are inherently fire resistant, or, self-extinguishing. Essentially, do not need additives to meet their requirement. Others plastics though, need additives to meet the requirement of being ‘FR’ or ‘self-extinguishing’.

Instrumentally, additives/compounds are added for a plastic material to have an improvement to its a flame-retardance. Furthermore, inhibit, vanquish and delay the combustion process. Also, these compounds are useful in the initial burning ignition stage of fire. So, the term flame retardant, refers to a material being, non flammable or inherently self extinguishing. Thus, making them suitable for use where fire protection is of great importance.

The typical attributes for fire retardant plastic materials behaviour are:

Firstly, Ignition.
Secondly, Spread of flame.
Thirdly, Heat release (or temperature rise).
Next, Smoke development.
And Finally, Smoke toxicity.

Undoubtedly, these attributes are critical. Moreover, in area’s where the spread of toxic fumes or flame. Such as, Aerospace, Marine and Rail. The term ‘UL’ is a plastics flammability standard released by the Underwriters Laboratories . Essentially, the standard classifies plastics according to how they burn in various orientations and part thicknesses from the lowest flame-retardant to most flame-retardant in six different classifications.

UL 94 Rating Definition of Rating Standards

So, broadly speaking, the most accepted industry standard for fire rating is UL. The USA Underwriters Laboratories (UL). Essentially, classifies plastics according to how they burn in various orientations per part thicknesses. Hence, UL 94 is a plastics flammability standard released by them . Crucially, a standard from the lowest flame-retardant to most flame-retardant. Thus, in six different classifications. Also, It’s worth noting, thicknesses can drastically change your part’s UL rating. Thus, UL ratings are measured at various ranges of sheet thickness. So, if you were looking for a UL 94 V-0 plastic material, for a component part, pay close attention to wall thickness and material selection.

HB Slow burning on a horizontal part.
V-2 Burning stops within 30 seconds on a part allowing for drops of vertical flammable plastic.
V-1 Burning stops within 30 seconds on a vertical part allowing for drops of plastic that are not inflame.
V-0 Burning stops within 10 seconds…………..

Further Standards

In addition to UL, the European Flame Retardants Association, EFRA, are the association representing major EU companies. Inherently, those that manufacture or market flame retardants in Europe. Also, closer to home, the relevant British and international standards are BS 2782 Part 1 Method 140A:1992 and its ISO equivalent, ISO 1210:1992.

Similarly, a standard specifically designed for the design of systems used in clean rooms is, FM 4910 certification is introduced. Crucially, to comply with the high fire behaviour requirements that FM Global places on approval in clean rooms.

Please note, for a machined fabricated plastic material that meets a particular countries or industries standard, please do get in touch. And, if our team can not advise, we can certainly put you in touch with the manufacturer or supplier of the specific fire retardant plastic materials.

Experienced Plastic Machining Turned Parts

Certainly, with most Engineering Plastics, while turning on a lathe, you can go extremely quickly with your feeds and speeds. Examples of some the materials are, Acetal, Nylon, PTFE, ABS, PVC and so on. Most noteworthy, in most but not all cases, the chips stay together, forming a ribbon and are easily removed from the Machine. Also, your tools will not dull or wear (practically not at all). Standard high-speed steel will be ample for turning every day Engineering Plastic. Whereas Insulation industrial Plastic require far more specialist care and techniques.

Next, it is worth noting, you do not need Machining fluid. That is to say, the surface finishes obtained, feel and look great. Also, high standards of tolerance and finish are achieved. Also, tools that cut steel or aluminium will generally work very well with most Plastic. So much so, in many cases, there are no special tooling requirements. Hence no added tool costs to pass on.

Experienced Plastic Machining Milled Parts

Similarly, for milling most Plastic, the above can be applied. Hence, the Engineering Plastic milled, are again, fast speeds and feeds, with some exceptions and individual preferences. Moreover, when milling Plastic, it can be less problematic than turning. Mainly due, to the lack of a ribbon, continuous swarf, being generated. Importantly, Sentinel has a large capacity milling capability. Also, with many Machines dedicated to specific materials to prevent cross contamination.

Certainly, because it has very low moisture absorption, it is also found in some high demand areas of marine applications. It is sometimes used in some cryogenic Components due to its low operating temperature abilities. Because of its resistance to wear and impact, UHMWPE continues to find increasing Industrial applications, including the automotive and bottling sectors. Since the 1960s, it has also been the most used Material for total joint arthroplasty in orthopaedic and spine implants.

Some Advantages of CNC Machined UHMW

UHMWPE is odourless, tasteless, and nontoxic
Has extremely low moisture absorption
Very low coefficient of friction
Self-lubricating and is highly resistant to abrasion
Very resistant to water, moisture, most chemicals
Resistant to UV radiation, and micro-organisms
UHMWPE only becomes brittle at temperatures below −150 °C.

Some Disadvantages of UHMW

Its melting point is around 130 to 136 °C
Not advisable to use UHMWPE at temperatures exceeding 80 to 100 °C for extended periods of time
UHMWPE will deform continually if the stress is present, an effect known as creep
Maybe not suitable for high load applications.

UHMWPE performance

UHMWPE has an incredible resistance to abrasion and can outperform almost any Engineering Plastic in this regard
It has a very low friction co-efficient and provides a bearing medium that is very free running and exceptionally long lasting
Also, it is resistant to many dilute acids, solvents and cleaning agents
It has a max operating temperature of plus 90°C and a short-term operating temperature of plus 120°C
A very tough Material, with the highest impact strength of any thermoplastic presently made.

UHMWPE also used for

Also, because UHMWPE has excellent abrasion resistance it is often used for sand, gravel or aggregate process applications. These environments are incredibly harsh on any bearing Material, but UHMWPE is one of the few Engineering Plastics capable of withstanding such punishing abuse.

UHMWPE can also be used for low friction pulleys because of its very low co-efficient provides a bearing medium that is very free running and exceptionally long lasting. It is often found in food production environments where high volumes of containers need to be guided along conveyors or production lines.

More characteristics of UHMWPE

High speed steel tooling is recommended. With, lots of back rake. Also, a generous nose radius. Finally, use caution when Turning UHMWPE . In the main, as the chips will be continuous and tend to wrap around the tooling.

Gluing and bonding

UHMWPE does not absorb water readily, nor wet easily, which makes bonding it to other polymers difficult.

Does UHMWPE have good Wear resistance?
UHMWPE is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel.

Chemical resistance

It is highly resistant to corrosive chemicals except oxidizing acids.

Unique characteristics UHMW

Its coefficient of friction is significantly lower than that of Nylon and Acetal, and is comparable to that of PTFE, or Teflon. Skin does not interact with it strongly, making the surface feel slippery, almost waxy.

Our UHMW Machined capacity includes but is not limited to the following: 8 No CNC Machines which includes Mazak VCN 530C + 5 No XYZ 1020 VMC + 2 Bridgeport’s VMC + 2 ProTurn Lathes + 1 Mazak Mill/Turn.
