Why Choose Silicone Rubber?

Silicone is a remarkable variety of rubber that offers some outstanding properties that can make it the clear choice among competing solutions. Firstly, silicone can handle very high temperatures in operation, up to 230°C (446°F). This allows it to maintain its properties at elevated temperatures that many other rubbers will not be able to handle! In addition, it has excellent resistance to UV and weathering, making it outstanding in outdoor applications. This includes heat, cold, freezing, direct sunlight, etc.

Silicone also has a low compression set – this means it can be compressed for a long period of time and will bounce back to close to its original profile when the weight has been removed. Think of this in a sealing application such as a door which is open and closed many times. The silicone will maintain the seal when compressed and will then return to its original form once the door is reopened. Also, the product is food safe and Redwood Plastics and Rubber can supply it in a new FDA blue variety.

There is a silicone rubber shortage currently in North America but not here! Redwood Plastics and Rubber carries significant levels of silicone stock in our central warehouse including FDA blue.

Rubber: It’s Not Just Tires!

When you think of “rubber” what is the first thing that comes to mind? It’s probably car tires, perhaps tires on your bike, but the point is “just tires” for many people. However, rubber is so much more than just tires. Rubber is used across a wide variety of industries performing in countless applications. Some are interesting, such as in prosthetics or medical devices. Others such as belt skirting on an ore conveyor are perhaps less interesting to the casual eye. Used in everything from mining, to sawmills, to even space – rubber should not be discounted as a simple material for tires! Gaskets, rollers, flanges, molded parts, wear parts, anti-vibration applications, electrical insulators – rubber has a place in all of those applications.

The short video below will display more applications that this versatile material can be used in. Maybe it will jump start your mind for a rubber application you might have?

Industry Spotlight: Aggregate

The aggregate industry is defined by the processing and movement of extremely abrasive wet or dry materials, usually by a network of conveyors. This process may also include equipment to pulverize, shape, clean, or otherwise sort the aggregates. Due to the abrasive nature of these materials, wear is a major concern on expensive equipment. Redco products have supplied viable, downtime-reducing, solutions for this industry over many decades. The primary workhorse is Redco polyurethane. This elastomer has extremely high wearing properties and can thrive in abrasive environments involving virtually any wet or dry aggregates.

The applications are too many to name but conveyor and hopper lining are two of the largest. When used as a liner, urethane protects the metal equipment and handles the wear of being in direct contact with the aggregate. However, polyurethane can essentially be used anywhere this wear occurs, including the area the aggregate first contacts the conveyor to any discharge chutes. Contact us with details of your application in order to get a recommendation of the optimal grade of urethane. Some polyurethane products actually exist specifically for aggregate including the innovative Redco Switchblade belt scraper with its replaceable and Redco Green Screens.

A few more notes. Rubber has significant applications in this industry as well, primarily as belt skirting and in areas where constant vibration is a concern. For slurry applications specifically, the Redco VYPUR series of pipe sections and elbows provide exceptional service life above and beyond metal in abrasive or corrosive applications. It’s best if customers reach out directly to us for a consultation, so if you’re involved in the aggregate industry and are looking for some solutions to maintenance costs and downtime, please contact us today.

Not Sure What Rubber You Need? Start Here

Ordering rubber products is easy enough when you know exactly what you need and a defined spec is available. However, what if that information has been lost? The answer is to start at “square one” and work your way up to an optimal solution. To that end you need to know five pieces of information:

  • Application – What are you doing with it?
  • Contact with – What aggregates or other materials will contact the rubber?
  • Exposed to – which chemicals?
  • Operating Temp – Lowest and highest?
  • Durometer – What is the hardness (example, 60A)?

The first four pieces of information on the list must be supplied by the customer and should be easy to put together. “Durometer” is a little trickier if not known as that requires a specialized piece of equipment. In that case, a sample of material can be mailed to us and we can test it here. Having this information will help us, help you maximize success in your application.

Plastic Plow Blades & Cutting Edges – Saving The Paving!

One of our employees recently took a couple photos after parking at an area we won’t disclose in Metro Vancouver a day after a recent snowfall. Upon pulling into his parking spot he noticed that every single stall had a large pothole where the snow had been pushed. Having been a weekly visitor to this lot he knew the holes were not there a few days before and therefore must have been caused by the snow removal contractor. The damage is extensive and will be a huge headache to fix! How much money will it cost to repair? What will happen to the reputation of this snow removal vendor?

And it was a completely avoidable disaster that never needed to happen.

Industrial plastic plow blades (or “cutting edges”) have been used for years to prevent this sort of issue. The cutting edges, made of polyurethane, rubber, or UHMW, are simple rectangular strips that are bolted to the bottom of a metal plow or bucket. Therefore it is this softer, non-damaging, plastic surface that actually touches the ground as the equipment scrapes and pushes the snow instead of the metal blade. There are multiple ways the metal-on-pavement contact can cause damage as besides creating potholes the blade can also destroy things like lights or reflectors embedded in the asphalt. Such as is common at airports for example.

The blades are an investment: even the least expensive blade will be at least a few hundred dollars. But how much is that few hundred dollar investment compared to losing contracts, a hit to your reputation as a contractor, and even potential lawsuits? The simple fact is you are “playing with fire” if you don’t have a high-quality plastic cutting blade – it’s an investment that must be made! Several plastics with different prices, properties, and suitability to applications are available so please contact us with the details of your application.

And save the paving!

Redco Anti-Slip Surfacing

Slippery areas at the workplace are a major hazard, that’s obvious but how do you prevent it? There are several options out there from painted coatings, to mats, to replacing the flooring with FRP (fiberglass reinforced plastic) grating. Sometimes grating and coatings don’t work and you need a customized solution and we’ll highlight three options available from us (we used a large picture to show the textures!)

1.) Redco Dura Grit

The large tile at center on the picture, Redco Dura Grit is a new product of ours. Dura Grit offers a cost-effective grit surface on rubber matting for aggressive applications and are customizable to any application. They lock together easily and can be installed for smaller application such as eye wash stations in just minutes! The holes in the matting allow liquids to pass through and under the matting. Each tile is 1 square foot, simply let us know how many square feet you need for your quotation. Ideal for washing stations, canneries, food processing, wash down areas, agricultural processing plants, showers, or anywhere a quick and easily installed anti-slip surface can be placed on another flooring substrate. These tiles last around three years in most applications*

2.) Redco Braxx

The blue and yellow tiles in the picture, Braxx offers a very strong UHMW substrate punctuated by raised “buttons” coated in either sand (blue) or clean coal slag (yellow). This material makes excellent stair treads or high-visibility safety flooring as it can be cut into the desired shapes, as long as those shapes can be made from 3′ x 9′ sheets. Braxx was originally designed to replace tapes and painted coatings for the U.S. Military.

3.) Redco LUNS

The small black tile in the picture, Redco LUNS is an extremely versatile and premium anti-slip option. Redco LUNS is a reprocessed UHMW that has an integrated clean coal slag surface (the slag is co-cast with the molten UHMW and cannot be separated). Redco LUNS should be used in the most aggressive applications and can be made of customized segments as long as they can be cut out of 3′ x 9′ sheet. LUNS was also originally designed to replace tapes and painted coatings for the U.S. Military.

For more information of a quotation on any of these products, please contact us today.
