Importance of RoHS Compliance

March 17th, 2015

rohs-compliant-01During the past decade, the government has been keen on promoting the use of environment friendly materials. However the use of plastic over the past decade or so has also been highly industrialized and commercialized due to its affordability as well as accessibility. Due to this, the European Union or EU made a law that oversees the careful formulation in the production of plastic and other materials. This law is called Restriction of Hazardous Substances Directive or RoHS. This was made into law in 2003 and fully implemented in 2006.

RoHS simply obliges all members of the European Union to responsibly produce and manufacture materials such as plastic. Furthermore, it assures the consumers that the plastics sold in EU member states are free from any toxic and hazardous materials like lead or mercury.


Why do consumers need to make sure that they buy products that are RoHS compliant?

Consumers need to do their part in saving the environment and in making sure that what they use are not hazardous to other people. When they buy plastic enclosures that do not have a seal that indicates RoHS compliance, they run the risk of exposure to toxic materials. This also means that the plastic product contains materials that can damage the environment.


What are the hazardous ingredients that consumers need to watch out for?

Non-RoHS compliant plastic enclosures may have one of the six most toxic materials in it. These are polybrominated biphenyl, mercury, hexavalent chromium, polybrominated diphenyl, cadmium, and lead. Prior to the enforcement of RoHS, one these six materials were used to produce plastic enclosures for electronics. So you need to make sure that when you select your plastic enclosures, there is a seal that states RoHS compliant.


Do all RoHS compliant plastic enclosures have RoHS seals?

Even though RoHS is being implement by the the European Union, the law doesn’t require all RoHS compliant plastic enclosures to have a seal or stamp of safety. If you are a consumer that wishes to purchase a plastic enclosure that is RoHS compliant, you just need to check if it is approved by any EU member or if the product has the WEEE seal. WEEE stands for Waste Electrical and Electronic Equipment which is a directive that promotes waste recycling.


If I buy a plastic enclosure, does it really have to be RoHS compliant?

If you really care for your health and the health of other people, then the answer must be yes. RoHS protects all consumers from exposure to toxic materials especially lead.


What plastic products are covered by RoHS?

Plastic products that are not exempted from RoHS are large and small household appliances like stoves, coffee makers, refrigerators, air conditioners, and even hair dryers. Computer hardware like printers, keyboards also need to be RoHS compliant. Consumer electronics like video game consoles, controllers, radios, televisions are also not exempted from RoHS.

This just shows the broad coverage of RoHS to ensure the safety of all consumers.


Are there plastic products that are exempted from complying?

Yes, there are still products that do not need to be RoHS compliant. Most of these are medical equipment and apparatus or large industrial tools.


What brands sell plastic enclosures with RoHS safety seal?

There are many brands that carry RoHS compliant products. One of these is SIMCO.


SIMCO has a variety of plastic enclosures that are RoHS compliant. You can even have a custom made plastic enclosure for your own device and you can be assured that it is free from toxic materials.


Are RoHS compliant products more expensive?

Safety is not always expensive. In fact, there are many affordable plastic enclosures that are RoHS compliant. SIMCO’s utility boxes or plastic enclosures can be as cheap as $4.00 each so you don’t need to worry about your budget. Safe plastic enclosures are cheap and durable too.



For the regular consumers who want to make their own electronic devices and choose their preferred plastic enclosures to go with it, you need to be aware of the importance of RoHS. It is not to restrict your choice or to limit your freedom in buying. It is to give you the peace of mind that what you are buying and installing is safe for you, your loved ones, and even the environment.

Aside from the RoHS seal, you might want to purchase plastic enclosures that are also WEEE approved. This means that if you decide to discard your plastic enclosure, the plastic will be recycled and be reused. This will ensure less garbage in the environment and promote recycling in the community.

So the next time you think of buying plastic enclosures, make sure that it is RoHS compliant. Double check the package if it has the WEEE seal or if it is EU approved to ensure your safety.

Choosing The Right Plastic Enclosure

March 15th, 2015

Our lives are heavily influenced by electrical gadgets.  Every single activity we do almost always involves technology and electrical power.  This is all the more true at every household all over the world.  The use of technology is not limited to adults; electronic gadgets are now made accessible to even the youngest member of the family.  Since this is the current trend, electronic devices must be placed in proper housings to ensure safety and prevention of any fire, leak, or static.

The most affordable yet durable and safe electronic housing for these gadgets are plastic enclosures.  There are various kinds of plastic enclosures; each designed for a specific purpose and use.  Should you need to use such enclosures, you need to know its kinds so that you will make the best and correct decision.  This will ensure safety of the device as well as the users.

The first thing to do when selecting the correct plastic enclosure is knowing where you will install it.  If you will install it indoors, away from elements of weather, then it is best to use ABS plastic enclosures.  ABS or Acrylonitrile butadiene styrene is a kind of plastic that non-hazardous, lightweight, and highly durable.  It is best used to protect household appliances or electronic gadgets.


SIMCO plastic enclosures are made of ABS Plastic Material.


If you will install the plastic enclosure outdoors, then you need to choose from several kinds that can best protect your device.  The best outdoor plastic enclosure that can withstand direct sunlight is the poly-carbonate type. Poly-carbonate plastic or PC is actually used as covering for greenhouses or transparent domes.  This is because PC plastics are heat and scratch resistant, which makes it the best option for outdoor use.

Another kind of plastic enclosure that is best suited for outdoor use is polyamide. Polyamide or PA can withstand extreme heat which makes it the best plastic enclosure for mechanical engines like car engines.  So if you think you will need to protect a device that will be operating for hours, then this kind of plastic enclosure will be your best option.  Polyamide will not melt nor deform under extreme temperatures.  The only weakness of polyamide plastics is humid weather.  If your live in the tropics, better not use polyamide.

If you need plastic enclosures that will be used in medical industries, then you may opt for the antimicrobial ABS.  It is similar to the ABS plastic mentioned previously, but the antimicrobial type is less durable.  The upside though is its ability to release ions that kill bacteria and viruses, which makes it the best option in the medical industry. It is widely used to enclose syringes, medical samples, blood works, and the like.

Another sturdy type of plastic enclosure is made from Poly (methyl methacrylate).  Poly(methyl methacrylate) or PMMA is a kind of transparent plastic that can, not only transmit light, but can also redirect it.  PMMA is best used when constructing large aquariums, skylight domes, and submarines.  PMMA can also be used in encasing musical instruments such as electric guitars and pianos.

If you are looking for plastic enclosures that can be protect your cellular phones, ebook readers, or tablets, then it is best to purchase thermoplastic elastomer.  Thermoplastic elastomer or TPE is made from the mixture of plastic and rubber.  This creates a flexible and sturdy material. Aside from protecting small gadgets like mobile phones and tablets, TPE can also be used to make nylon tubes that can protect wires and cables.  The advantage of using TPE is that it is recyclable.  This appeals to environmentalists all over the world.

Another kind of plastic enclosure that can appeal to environmentalists is biograde plastic. What is unique with biograde is it is made from cellulose which is an organic ingredient.  It is heat resistant and easy to mold.  It can be used to protect your electronic device but it can also be used for food storage.  That is how safe biograde is.

Now that we have listed all the different kinds of plastic enclosures, you can now be assured to pick the most suitable ones for your needs.  Whether it is for indoor or outdoor use or for electronic or manual devices, all these plastic enclosures are available online and at your nearest hardware stores.
