Wastewater Solutions

If you stop for a moment and think about wastewater treatment what comes to mind? Chances are you are you think first of a putrid smell. Perhaps an endless labyrinth of pumps and pipes surrounded by rust. Maybe algae clinging on to walls or walkways. No matter what you imagine, the words “grime” or “dirty” probably enter your mind.

While our imagination tends to exaggerate, employees of wastewater treatment know it is a very tough environment and issues with corrosion and rust are prevalent. Fortunately, plastics are well-suited to provide solutions for wastewater treatment. In the past, our polyurethane has been especially useful. Redco™ urethane has successfully replaced rubber in multiple applications and our bearing grade urethanes, Redco™ 750 and 750 SXL, outperform traditional materials like brass.

Our new FRP lineup provides a wide variety of structural solutions for wastewater treatment. Our Redco™ DURAGRID® and DURAGRATE® provide a corrosion resistant and non-conductive surface. Redco™ SAFRAIL™ provides corrosion resistant industrial handrails, ladder and cage systems that are virtually maintenance free. A few examples of our wastewater solutions are here.

Why Choose Phenolics?

Some plastics are easier to discuss than others. For example, although we recently wrote an article on the properties of polyurethane, most (if not all) people have at least heard of polyurethane and likely encountered it in certain consumer products like skate wheels. Industrial laminates, commonly called “phenolics”, are a different matter.

What are industrial laminates? You likely use them everyday, you just don’t know it. Have you ever seen the circuit board within your computer? The brown board the chips and wires are attached to is an industrial laminate. Phenolics have a use within many industries; however, they have a niche within the electronics industry due to their electrical insulating properties. Phenolics are made of alternating layers of resin and material: usually cloth, paper, or glass-based fabric. The resins used are epoxies, melamines, silicones and polyesters. These materials are sandwiched under extreme heat and pressure forming a solid thermoset plastic with many useful properties.

Key characteristics across all phenolic types include corrosion resistance, good electrical insulating characteristics and good machinability. Not only do phenolics come in sheet form, as one would expect from a laminate, but they can be filament wound into strong tube shapes useful as bearing material.

PAPER BASED laminates are used when electrical insulation values are the most important feature. They also have the benefit of being the least expensive industrial laminate.

CLOTH BASED m are selected when greater mechanical strength than paper laminates are required. Two primary cloth types are used: canvas and linen. Canvas has better mechanical strength; however, linen has a finer texture and is easier to machine.

GLASS BASED fabrics have the best overall properties. They do not absorb much moisture, have excellent electrical and mechanical properties.

Each resin has its own strengths and weaknesses as well.

Phenolic resin – Extremely hard, high load capabilities.

Epoxy resin – Virtually no water absorption, great electrical insulation, good temperature and chemical resistance.

Melamine resin – good solvent and chemical resistance, available in almost unlimited colors.

Silicon resins – Retain properties over a wide temperature range, bio-compatible.

Polyester resins – Low cost and good arc resistance.

We hope this has shed some light on the remarkable properties of industrial laminates. If you have any questions about Phenolics or our other plastic products please contact us.

Redco Introduces New FRP Product Lines

Recently Redwood Plastics Corporation and Strongwell, the world’s largest producer of pultruded materials, signed a distributorship agreement. This has greatly expanded Redwood’s Fiberglass Reinforced Plastic (FRP) product lineup. The pultrusion process allows for materials to be produced in almost unlimited lengths, limited only by the application and freight restrictions. With the number of new products available we wanted to draw attention to a few highlights.

Redco™ SAFRAIL™  fiberglass handrails is a pultruded product suitable for a wide variety of industrial applications. SAFRAIL™ meets OSHA strength requirements and provides a 2:1 safety ratio. Redco™ SAFRAIL™ is particularly well suited to corrosive environments where liquid or airborne corrosive agents, such as salt, may be present.

The product outlasts other metals including aluminum and is non-conductive and maintenance free.  SAFRAIL™ is easy to install with its internally bonded fiberglass connectors meaning no visible rivets or metal parts.

Redco™ DURADEK® is a standard pultruded grating system that offers numerous advantages over traditional metal materials. Like other FRP materials, Redco™ DURADEK® is corrosion-resistant, non-conductive, and maintenance free. The product is flame-retardant and securely bonded with a proprietary method utilizing a 3-piece cross-rod system.

Redco™ DURADEK® has been successfully used in various industrial applications, notably in marine and waste treatment. The grating is available in both polyester and vinyl ester resins and includes a synthetic surfacing veil for increased UV and corrosion resistance.

Redco™ EXTREN® is a series of fiberglass reinforced building shapes and structures available in over 100 standard dimensions. Its properties include high strength, lightweight, corrosion resistance, low thermal and electrical conductivity and electromagnetic transparency.

That electromagnetic transparency property of Redco™ EXTREN® makes the material especially suited for applications such as cell phone towers or buildings involved in the scientific testing of systems like radar.

Redco™ EXTREN® is available in three grades: Series 500 (polyester resin with UV resistance), Series 525 (polyester resin with increased flame-retardant properties) and the Series 625 (Vinyl Ester resin with premium fire retardant and corrosion resistance properties).

Lubx Creates Energy Savings

Energy costs are a major threat to modern business. As the world’s emerging economies continue to grow the pressure on energy sources (and the price of energy) will only increase.

FDA compliant Redco™ LubX® is a new High-Performance plastic designed specifically for material handling applications. Redco™ LubX® has remarkable “dry-run” properties providing a very low coefficient of friction without the addition of liquid lubricants. This reduces the energy required to transport materials along the conveyor chain, resulting in energy savings. In fact, the coefficient of friction is up to 75% less than standard UHMW-PE, already itself valued for low-friction properties.

Another unique feature of the polymer is that it was designed to have as low a friction coeffecient as possible with sliding partners, in order to reduce, if not eliminate, the slip-stick effect. For example, compared to UHMW, Redco™ LubX® slides 75% better against Acetal and 60% better against steel.

Redco™ LubX® is available currently in rod and sheet form from 1/4th” to 4″ thick in a blue-grey color.

Customized PTFE Parts for Bottling Plant

Recently Redwood Plastic contacted a client who was restarting a bottling plant. The original equipment manufacturer was located in Europe and a variety of parts would need to be sourced via expensive and time-consuming shipping. After consultations with the Plant Operations Manager, 500 examples (100 each of five different parts) were produced with design modifications which ended up improving production. These new parts not only saved our customer costly shipping fees, but saved them time, and increased their production.

All parts were fabricated with Redco PTFE,  which has the lowest coefficient of friction in our current product line, is non-reactive, self-lubricating, and has excellent temperature tolerance (up to +500F). Redco PTFE makes an excellent choice for a variety of parts, especially when sliding between parts or on surfaces.

BUSHINGS & BEARINGS – Why Plastics are Better…

Plastics are among the most obtainable and cost-effective materials used in a variety of applications. They are easy to fabricate, durable and efficient, resulting in an ideal material for bearings and bushings.

SN InsertsBecause of plastics sheer usefulness and malleability, some plastic bushing grades can be designed for extreme environments and can withstand extremely high or low temperatures. Others are even suitable for hazardous environments with high levels of shock and vibration.

• Self lubricating

• Outstanding load bearing properties

• Excellent for impact and shock application

• Exceptional wear life and resistance to corrosion

• Low temperature resistance to -80°F

BearingsDifferent plastic grades can also be bonded together. For example, feed rollers would have a softer outer diameter with a harder inside diameter. Bringing these two materials together creates the perfect balance of shock absorption and grip with high load bearing capabilities. Metals (steel, bronze, etc) can also be bonded to plastics.

Please Consider:

Plastic Clearance/Tolerance is subject to many variables (i.e. Moisture, Cold Heat) when being machined for specific applications. If lubrication is supplied to a plastic bearing, the load and life are greatly increased dependent on the type and volume of lubricant. Consult our Machining Chart available on our website.
