Your Guide To Polycarbonate

Polycarbonate can be thought of as somewhat similar to glass. It’s a transparent material that can be extruded to create a number of commercial products. Some of the most popular include bulletproof glass, eyeglass lenses, PPE, and exterior lighting fixtures.  This material is used in situations where strength and impact-resistance are required. Polycarbonate is a strong material that is resistant to both high temperatures and impact. Many prefer to use polycarbonate instead of traditional glass because it doesn’t shatter.  A Thermoplastic Material Polycarbonate is well-known for being a thermoplastic material. Any thermoplastic material is capable of being heated up and formed into a product. Once a melting point is reached and the polycarbonate material turns into a liquid, it can be shaped into almost any product.  Thermoplastic materials can be melted, cooled, and reheated all over again without causing any major degradation to the material. This property makes thermoplastics like polycarbonate great for manufacturing as they can be recycled over and over again- a very important feature in today’s environment. What Is Polycarbonate Used For? Keller Plastics produces many different polycarbonate extrusions that companies use throughout the country. Since polycarbonate is very transparent, light-weight, and sustains its integrity in high-impact situations, it’s used in a variety of applications in almost all industries. Some of the most common products made with extruded polycarbonate include: Windows Eyeglass Lenses Machine Guards LED Light Pipes Wall Protectors Display Cabinets Polycarbonate extrusions are very popular as a convenient alternative to glass. While most polycarbonate is left in its natural state of transparency, it can be tinted. One of the most desired applications is tinting the polycarbonate to naturally reduce the sun’s glare on outdoor signs and light covers.  Polycarbonate Grades And Additives Extruding polycarbonate is not always easy but Keller Plastics extrudes it every day. The material must be dried thoroughly before extruding and Keller Plastics has special dryers to do this. Keller Plastics also runs a special UV stable material for solar panels that are expected to last over 20 years. Many other additives can be utilized in polycarbonate production to achieve various results for different applications. Some common polycarbonate grades that you’ll find on the market today include: Glass-Filled General Purpose Light Diffusing Flame Inhibiting Low Flammability Antimicrobial Bullet Resistant UV Blocking Are There Any Disadvantages Of Polycarbonate? While polycarbonate has many strengths, like high impact resistance, it does have one major disadvantage. The material is susceptible to scratching. More recently, Keller Plastics, alongside other manufacturers, have started coating the polycarbonate products with a scratch-resistant layer to ensure optimal protection.

The Process of Plastic Extrusion

The process of plastic extrusion at Keller Plastics involves the heating of polymeric compounds to the point of melting, at which point they are pressed through a die that is attached to the front of the extruder. Plastic extrusions can be made into many shapes. A conveyance system at the end of the line allows the profile to be boxed. The specifications of an individual job request will determine the precise sort of compound added to a hopper that sits over the screw opening, which itself is at the back of the extruder system. The components such as the screw and the barrel in which it is contained are heated so that the polymer is melted gradually, while the materials are sent toward the head of the extruder via the screw. Upon reaching the front portion of the extruder, the polymer material is pushed through a custom opening made to suit the product’s specifications. It may be in the form of a tube, rod, or an alternative profile. After the material leaves the front of the extrusion machine, the heated material is sent to a tool engineered to prepare it for shaping into the desired extruded plastic profiles. Tooling equipment then ensures that the material is the correct shape and size required by the customer’s specifications and meets their print. Because extrusion of this sort involves the melting of polymers, the ultimate shape and size of the part being made will be influenced by the tooling being used, but also by the person operating the extruder. This person is responsible for regulating the melt conditions and also for the cooling process that occurs at later stages of the process. Every extrusion line is equipped with a takeoff unit at the end so that tension is exerted on the material as it leaves the extruder. This plays a significant role in the speed of the extrusion line as well as the final plastic extrusion shape. At the very end of the extrusion machinery, the parts will be cut to the designated length or put on spools. Once the parts are finished by the professionals at Keller Plastics, they are placed in containers uniquely suited to the product type, where these can take the form of bundles, boxes, or bulk packaging. The final step in the process is when the completed extruded plastic profiles are shipped directly to the location designated by the customer. Keller Plastics can handle all aspects of shipping to the final site. Call us Today – (603)...

Products Produced With Plastic Extrusion

When melted plastic is forced into a die to create plastic profiles, the resulting products are known as plastic extrusions. The type of plastic preferred by manufacturers is known as thermoplastics. These are ideal for plastic extrusion as this type of material can be easily melted and cooled down into a new form without compromising its strength. The most common types of thermoplastics used by plastic extrusion manufacturers are PVC, polypropylene, ABS, Polycarbonate, and Nylon. Depending on the end application, one material will be preferred over the other. Keller Plastics uses many different materials to create fully customized products for any application. Tubing Keller Plastics produces various tubes and pipes. These products can be as small as a drinking straw to as large as city sewer pipes. This tubing may be responsible for transporting everything from gasses to liquids. Apart from crafting custom lengths and sizes, Keller Plastics can also produce tubes with different wall thicknesses. Profiles Plastic Extrusions can produce cross-sectional shapes to a variety of specs. These shapes can be produced in many different sizes, depending on the end product. Some examples of profiles include railing, trim, and rain gutters. Solid Extrusions Not all plastic extrusion products are hollow. Rather, there are solid extrusions that can be used to create products that are maintenance-free and weatherproof. Some examples of these products include outdoor furniture, benches, deck planks, and fence posts. Film And Sheets Plastic extrusion manufacturers can produce thin film and sheeting products for consumers. Some of the thinnest products include window glazing, protective screens, and blister packs. These can be used for tinting car windows, protecting smartphone screens, and packaging medication. Insulation When it comes to protecting electrical products, plastic extrusion is the most popular process used. The plastic insulation that you’ll find around wires is crafted via the plastic extrusion process. This works by having a wire put into a die. Then, the plastic product is melted down and forced into the die. Once cooled, this creates a plastic insulation layer around the wire to ensure it’s waterproof and abrasion-resistant. If you need help with plastic extrusions, give Keller Plastics a call. We’ll bring our experience to the table to provide you with a variety of plastic extrusion products that meet your needs. We’ll even provide you with free tooling so that you can be assured that you’ll get the products that you desire. Call us Today – (603)...
