It is a Better Alternative to Plastic
Borosilicate glass is a superior material for use in many applications. It has increased thermal shock resistance, which makes it less susceptible to breaking due to changes in temperature. It is also more durable than soda lime glass. Its benefits are numerous and are worth a closer look. Read on to learn why borosilicate glass is a better alternative to plastic. Here are three reasons.
When used as intended, borosilicate glass is completely safe for drinking and is completely dishwasher and microwave safe. Borosilicate glass is more durable than most plastic products, making it perfect for kitchenware and electronics. It can withstand extreme temperatures without cracking, which makes it the perfect material for chemistry labs. It is also heat and acid-resistant, which means it will not crack under pressure or damage other materials used in manufacturing them.
Some plastics can be recycled many times, but some of them lose their integrity over time. Plastic bottles often go to the landfill before they can be recovered. Glass bottles, on the other hand, can be recycled many times without losing their quality. While glass bottles are more expensive to produce, their carbon footprint may be similar to plastic ones. Some reports state that recycling plastic bottles is better for the environment and cheaper for the manufacturer than making new ones from glass.
One major benefit of using glass is its unlimited recycling life. Glass is 100% recyclable, which means that once you recycle glass, you can make new ones without any damage. Moreover, you can reuse recycled glass for producing consumer products. Glass can be used as a storm window or door insulation. It can even be used as thin layers of fiber for transportation vehicles to improve fuel efficiency. So if you're looking for a plastic alternative, consider borosilicate glass.
Glass is much heavier than plastic, so it is more fragile. In a laboratory, moving between lab equipment can be tricky. A broken glass container will release hazardous materials and make the space even more dangerous. Additionally, glass labware is prone to breakage, making it more expensive to replace. Broken glass will also result in the loss of valuable reagents and hazardous solutions. Therefore, plastic is the better choice.
It is a Higher-Grade Glass
