The Difference Between Liquid Silicone and Gumstock
Throughout history, scientists and inventors have created new solutions to everyday problems. Often times, the original method is only used until a superior solution comes along. At first we used a mechanical printing press, now your local print shop can process an order of 1,000 copies in a matter of minutes. The vehicles that we drive every day have seen vast improvements in safety and durability compared to previous models. In the same way, the silicone molding process has also undergone changes. Gumstock molding is a more traditional method, but Liquid Silicone has surpassed it in several ways, here are a few of the differences between the two types of silicone:
Liquid Silicone vs. Gum Stock
Gum Stock Silicone, or High Consistency Rubber (HCR) is a type of silicone that has the consistency of a thick putty or dough. It is often used in compression molding by placing the silicone into an open air molding press to form products. This process is fairly labor intensive compared to Liquid Injection Molding, especially when you are creating a product that requires specific customization.
On the other hand, Liquid Silicone has a consistency similar to petroleum jelly and it is made using a two-part system that is mixed as it is used. Liquid Injection Molding makes it much easier and less expensive to create custom features. At Si-Tech, we use silicone injection molding for all of our customers because it offers many distinct advantages.
Advantages of Liquid Silicone
Liquid Silicone Injection has made the process of customization much easier compared to Gum-Stock Silicone. Because liquid silicone is injected into two part molding system, customization is simple. Insert molding is achieved by having two molds, one mold to make the inserts such as colored keys, clear windows, or light pipes. Once the inserts are molded, they are placed into the keypad mold.
Liquid silicone uses a cross-link bond, making keypads more durable than gum-stock. As keypads undergo significant use, liquid silicone keypads have held up much better over time.
Time & Cost
Overall, Liquid silicone is a far less labor-intensive process, which means it is also less expensive. The main difference is that the cure time for liquid silicone is about 1/3 less than gum stock. Due to the way the different materials are processed, it can be much more time efficient to use liquid silicone molding – saving you time and money.
At SiTECH, we only use liquid silicone for all of our products, allowing us to be more dependable in duplicating our processes. We have made silicone products for many industries, and we would love to help you with your next product, contact us today!
When to Use Silicone Lubricant
Silicone lubricant has many forms, and even more uses to its name! As such, understanding when to use a silicone lubricant vs. when you should be using a dry lubricant for example is important in the effectiveness of the overall lubrication task.
Silicone lubricant can be used in the forms of an oil, which is non-reactive to most substances, maintains it's greasiness in extreme temperature conditions and does not oxidize, or a silicone spray which is not only water resistant, but also allows you to lubricate those hard to reach places like mechanisms or bearings.
This article will explore when to use Silicone lubricants specifically, the main uses of a silicone lubricant, knowing what materials to use a silicone lubricant on as well as how to waterproof using a silicone lubricant.
The main uses for silicone spray lubricant
As we mentioned earlier, silicone lubricant spray uses are plentiful. Whether you're a professional tradesman, handy man, or someone who uses tools in your day-to-day life, you understand how important it is to keep your tools and equipment working in top condition. Part of that means keeping your tools well lubricated and clean.
A silicone lubricant spray is an excellent product to use on tools because it of course lubricates, but also reduces friction and helps to drive out moisture. In fact, silicone lubricants are especially handy for wooden tools by preventing the wood from drying out and splintering.
On the other hand, silicone lubricant sprays can also be used on a wide range of home applications that you may not have thought of! Try lubricating the sliding door track with silicone spray to keep it moving, or extent the life of zippers on clothing, backpacks, sleeping bags, etc. and keep everything moving smoothly.
When to use silicone spray on rubber parts
The many uses of silicone spray don't stop there! In fact, the question isn't “what is silicone grease used for?” but rather “what isn't silicone grease used for?”. Silicone grease is especially effective at sealing rubber parts, but what's the best silicone spray for rubber? We'll get to that later.
Have you ever considered how many rubber parts are in your car? Or perhaps your dishwasher? Many day-to-day items that we've all come to rely on are comprised of thousands of rubber parts in varying shapes and sizes.
Rubber is everywhere!
Due to rubbers naturally slip resistant nature making it difficult to install, it's not unusual for rubber parts to slip during assembly where an o-ring may get twisted, a heater hose may not be fully inserted, or a gap appears in a waterproof seam. Coating rubber parts prior to assembly helps to avoid some of the aforementioned problems.
One of the most common uses of silicone spray on rubber parts is that of replacing car window rubber seals. To do so, simply remove the rubber with a flathead screwdriver, scrub the glue with a solvent and sand the metal.
