Applications of Cyclic Olefin Copolymer

Cyclic Olefin Copolymer or usually called COC for short is an amorphous polymer. Compared to polyethylene or polypropylene, it is relatively a newer class of polymer. It is a thermoplastic with high performance that is formed by combining norbornene which is a cyclic olefin monomer with ethylene which is a standard plastic building block. Compared to other polymers, COC is a remarkably pure polymer that is rigid and clear as glass in its natural state. The applications of COC are countless because of its spectacular properties.

Strengths and limitations

There are a few limitations of COC plastics. They are quite sensitive towards stress cracking, and their glass transition temperature is between 75°C and 170°C. Although they have their limitations, they have their strengths and advantages. They have great resistance to steam sterilization, polar solvents, and gamma radiation. Their clarity is very high in transparency which makes them clear as glass. Compared with other transparent polymers, they have satisfying biocompatibility and their dimensional stability is excellent. A great strength to point out is their capability as exceptional moisture barriers. Unlike other polymers that are sensitive to moisture, COC is unaffected by it.

Properties

The electric properties of COC plastics are present since it is made up of low dielectric constant materials that are good materials for creating electronic components in low permittivity or high-frequency applications and it is an excellent insulator. The optical properties of COC are astounding since it is very similar compared to glass. They are exceptionally high in transparency with high heat resistance, high Abbe number, and low birefringence. The chemical properties of COC show that it has good chemical resistance to attacks from bases and acids. They are also great barriers to solvents like alcohols.

Applications

COC can be applied to many things in various industries. With its many features and properties, their application in producing products are of high quality.

Medical

kjfwep984There is a number of medical applications of COC since it is transparent, sterilizable, it has biocompatibility, and is a barrier to moisture. It can be used to produce test tubes, glass vials, needle injectors, inhalers, syringes, specialized labware and even mycobacteria growth tubes.

Optics

Since COC has high transparency, low birefringence, consistent refractive index, good metallization, and high dimensional stability, they are ideal for optics applications. They are used to manufacture optical data discs, high precision lenses for printers, copiers, cameras, and reflectors.

Packaging

kbpeb239COC can be used for consumer applications such as healthcare, food, and general packaging. With their enhanced stiffness, thermoformability, dead-fold, shrink, easy tear, high moisture barrier, and heat resistance, they are perfect for packaging applications. They can be applied in creating transparent food barrier films, pharmaceutical jars and bottles, protective or bubble wrap, and various films including shrink films, twist films and forming films.…

How to lose weight safely

Being overweight is one of the most common health conditions all over the world. It comes with increased risks of diabetes, heart conditions, stroke, and many others. You should thus try as much as you can to lose the extra body weight. The weight loss method that you choose to use should be safe and effective. Below are a few ideas to help you achieve your weight loss goal.

Safe weight loss measures

Improve your diet

hgvcgdfxfgfg4545677456

You may need to start dieting for you to lose weight effectively. Dieting, contrary to what many people think, does not refer to starving yourself. It is simply consuming the right types and amount of food, at predetermined times. Your meals should contain lots of vegetables and fruits. Such will give you the feeling of satisfaction and keep hunger pangs away, without packing you up with calories. Remember to consume small portions only at a time. The idea is to take in fewer calories in comparison to the number of calories that you use.

Drink more water

Keeping your body well hydrated is also very important when it comes to weight loss. When you get dehydrated, your metabolism slows down and counters the weight loss efforts. Drinking water before a meal will also reduce the quantity of food that you will consume. This means you consume fewer calories than you would without drinking water. The amount of water to consume is a minimum of eight glasses per day.

Work out

ythcfrtfygkuybmj5ee324356Engaging in physical activities is another great way to lose the extra body weight. The type of physical activities that you choose to engage in may vary depending on your current body weight and physical fitness. The more you work out, the more calories you lose and hence, the more weight you lose. However, keep in mind that over-exercising may result in other health problems. A great idea would be to enroll in a gym and get a coach to help you with your workouts.

Get adequate sleep

You should ensure that you get an average of eight hours of peaceful sleep every night. It will help with weight loss in two different ways. For starters, you will find yourself snacking on different types of food when you are awake. You get to avoid taking in all the calories from the snacks when you are asleep. You also give your body ample rest, which allows you to be more active during the day. Being physically active contributes to weight loss.

Online shopping tips

Shopping online offers a wide variety of benefits and conveniences. It is currently the most preferred way of shopping. However, not all shoppers enjoy the experience that they get shopping online. Some of the bad experiences you can get include poor services, delays, or even falling victim of fraud. Below are some tips, which will help to ensure you enjoy a smooth online shopping experience.

Tips to use when shopping online

Choose the right site

The site that you choose to shop from will largely determine the kind of shopping experience that you will have. Start by considering the safety features. This will help you avoid being a victim of fraud, which can result in great financial losses. Make sure that the site is well known and trusted by many online shoppers. Avoid using search engines to land at the shopping site. If it is your first time shopping online, ask your friends or colleagues to refer you to the best sites based on what you wish to buy.

Work with a budget

Shopping online is usually a lot of fun. You are exposed to a wide variety of products, which you can buy. It is very easy to be carried away by that and end up buying many items that you had not planned for. The advertisements, offers, and promotions will not make it even difficult to avoid the temptation of impulse shopping. To help you out, you should create a budget for everything that you need and focus on buying only the items that will be on the budget. There are many online tools which can help you create a detailed budget.

Look for offers

gjgjfdthg65265A majority of online shops usually attract customers by giving offers. You should ensure you take full advantage of the offers to help you make some savings. Start by shopping around to find the trusted online shop that has the best offers. Some of the offers may not be presented in an obvious way, in a bid to discourage you from taking the offer. A discount voucher, for example, may require you to source it from a different page and find out how to apply it. Remember to check the shipping charges as not all sellers offer free shipping. Avoid offers that are too good in an unrealistic way as they indicate a possibility of fraud.
