Whether or not to use a plastic screen cover on your phone is a subjective choice. While some people prefer to use a screen protector to keep their phone's surface pristine and avoid scratches, others argue that it hinders the user experience by altering the screen's appearance and creating an additional gap between the user's finger and the screen. It's worth noting that modern smartphone screens are made of laminated glass, which is designed to shatter upon impact to protect the rest of the device. Additionally, plastic screen protectors may not offer the same level of scratch resistance as the original screen, and they can be tricky to apply without bubbles or cracks. Ultimately, the decision comes down to personal preference and how concerned the user is about minor scratches or resale value.

What You'll Learn
Scratch resistance of plastic screen protectors
Scratch resistance is an important feature of screen protectors, as it helps to maintain the pristine condition of a device's screen. A scratch-resistant screen protector acts as a physical barrier, safeguarding the device from scratches, scrapes, and abrasions caused by everyday objects like keys, coins, or rough surfaces.
Plastic screen protectors, such as those made from TPU (thermoplastic polyurethane), are flexible and can absorb the shock from bumps and non-extreme drops or impacts. They offer better screen clarity than PET (polyethylene terephthalate) plastic protectors and can protect against and hide light scratches. TPU protectors are also more flexible and less prone to chipping or cracking than glass. However, they may not offer the same level of scratch resistance as other materials, such as tempered glass or sapphire.
Tempered glass is created through a process of heating and rapid cooling, resulting in a durable and scratch-resistant surface. It offers enhanced impact protection and scratch resistance compared to traditional glass. Some tempered glass screen protectors also feature additional technologies, such as impact protection and blue light filtration.
Sapphire screen protectors, such as Shellrus, offer excellent scratch resistance but are more brittle and prone to cracking. They tend to be more expensive than other options.
Liquid screen protectors, made from silicon dioxide, are another alternative. They can help hide scratches and are scratch-resistant, but they don't offer much protection against high-impact drops or deep scratches.
While plastic screen protectors may not offer the highest level of scratch resistance compared to other materials, they can still provide adequate protection for those seeking a more affordable and flexible option.

Shatter protection of plastic screen protectors
Plastic screen protectors are a common and inexpensive way to protect your phone screen from scratches and cracks. While they may not offer the same level of clarity and smoothness as glass screen protectors, they can provide adequate protection for your device.
One of the main benefits of plastic screen protectors is their scratch resistance. They act as a sacrificial layer, taking any scratches that would otherwise damage your phone screen. Plastic screen protectors can also help to absorb the impact of falls and drops, reducing the likelihood of cracks or shatters on your screen. Additionally, plastic screen protectors are easy to install, with some models featuring alignment trays that ensure a flawless fit.
However, it's important to note that plastic screen protectors may not offer the same level of protection as glass or tempered glass options. While they can help prevent scratches, they may not provide the same level of shatter protection as stronger materials. Additionally, plastic screen protectors can sometimes be more prone to dust buildup around the edges and may not offer the same clarity and touch sensitivity as glass alternatives.
When choosing a plastic screen protector, look for options made from durable materials such as polycarbonate or thermoplastic polyurethane. These materials offer impact resistance and can help protect your screen from cracks and scratches. It's also important to ensure proper installation, as air bubbles or misalignment can reduce the effectiveness of the protector and impact the overall aesthetics and functionality of your device.
In conclusion, plastic screen protectors can be a cost-effective way to safeguard your phone screen from scratches and minor impacts. While they may not offer the same level of shatter protection as glass alternatives, they can still provide a good level of defence, especially when combined with a sturdy phone case. By choosing a high-quality plastic protector and installing it correctly, you can enhance the durability and longevity of your device's screen.

Durability of plastic screen protectors
Plastic screen protectors are a popular option for those seeking a budget-friendly solution, with prices typically ranging from $5 to $15. They are constructed from flexible polymer layers, usually made from PET (polyethylene terephthalate) or TPU (thermoplastic polyurethane), that conform to the screen's surface. This flexibility makes them highly adaptable, especially for phones with curved or non-standard screens. With a thickness of 0.1 to 0.3 mm, they are thinner and lighter than tempered glass alternatives.
However, one of the drawbacks of plastic screen protectors is their lack of durability. They have a much shorter lifespan than tempered glass protectors and are more susceptible to scratches and scuffs due to the softer material. While TPU protectors may have self-healing properties for minor scratches, they cannot match the long-term durability of glass. Additionally, low-quality plastic screen protectors may be less environmentally friendly, as they are typically made from non-biodegradable materials.
On the other hand, tempered glass screen protectors undergo a unique manufacturing process that enhances their strength and durability. The glass is heated to extremely high temperatures and then rapidly cooled, creating tension and resulting in a stronger and more durable material. This process gives tempered glass a higher hardness rating, typically labelled as "9H" on the Mohs scale, making it resistant to scratches and everyday wear and tear.
While tempered glass offers superior durability, it tends to be more expensive and may not be as adaptable to curved or non-standard screens due to its rigidity. Ultimately, the choice between a plastic or tempered glass screen protector depends on factors such as budget, the shape of the phone screen, and the desired level of protection and durability.

Plastic screen protectors' effect on screen performance
The debate between tempered glass and plastic screen protectors has intensified with the influx of new smartphone accessory brands on the market. Consumers are torn between choosing the option that offers the best protection and value. While some prefer plastic screen protectors for their affordability and scratch resistance, others opt for tempered glass protectors for their superior durability, clarity, and user experience.
Plastic screen protectors, such as PET and TPU, are popular choices for safeguarding smartphone screens from scratches, smudges, and minor impacts. They are known for their thinness, affordability, and moderate scratch resistance, with a hardness rating of 3H on the pencil hardness scale. Plastic protectors, especially those made with PC (polycarbonate), offer enhanced durability due to their strength and impact resistance. They also provide customizable designs, a clear and transparent appearance, and cost-effectiveness.
On the other hand, tempered glass screen protectors offer superior protection, clarity, and user experience. While they are more expensive initially, their durability and performance often provide better value in the long run. Glass is always going to be more scratch-resistant, and while it may not protect your device from cracking if dropped, it can add a small amount of "drop protection" due to its thickness.
Some users have expressed concerns about the environmental impact of screen protectors. Both plastic and tempered glass protectors have their merits in this regard, as they are recyclable and have lower carbon footprints compared to glass production. However, improper disposal of plastic waste can harm wildlife and pollute ecosystems. Therefore, choosing reusable or recyclable options and properly disposing of used screen protectors are important considerations when evaluating their environmental impact.
Ultimately, the decision between a plastic or tempered glass screen protector depends on individual preferences, budget constraints, and specific needs. While plastic protectors offer affordability and scratch resistance, tempered glass protectors provide enhanced durability, clarity, and user experience.
