RAYDA PLASTICS - MAKING HIGH QUALITY EXTRUSION PRODUCTS SINCE 1976.
Plastic has many uses in our day to day lives, often going unnoticed and being considered a common convenience without any real thought about the vast properties of the material and how much we rely on it.
Depending on usage too, plastic can often be made with different properties to withstand the particular use intended. Here, we go through some of the main properties of plastic when designed and manufactured for domestic and industrial use.
To be classed as truly sustainable, a material must be environmentally, economically and socially sustainable. Many plastics are recyclable, and provide fantastic benefits to many industries. In fact, in recent times, many manufacturers are finding ways to make plastic use more sustainable without compromising these benefits

It’s not uncommon to see plastics revolutionising a number of different industries, but one sector where plastic innovation has made huge developments is within the medical industry.
Thanks to plastic, new equipment and medical storage solutions have been created, extraordinary treatments have evolved, and lives have been saved.
Here are some of the most notable plastic innovations in the medical industry.

In its very basic form, the extrusion process involves melting plastic granules, pulver or pellets, pushing them through a die to create a shape. This shape is then cooled and set to the correct dimensions and then cut to the right length.
Co-Extrusion requires multiple extrusion machines forcing two or more different materials through the same die, creating a single piece of layered or encapsulated part. The resulting part can yield properties distinct from that of a part produced using a single plastic, due to the combined materials.
Sometimes, five or more materials will be used in a single cycle, but each individual plastic will retain its original properties while being combined into a single part.

Taking place at the Huntington Convention Centre in Cleveland, USA, 8-9th May 2019, the Plastics Extrusion World Expo is a free-to-attend tradeshow where exhibitors and visitors alike can come together to celebrate the innovation, insight and education found within the plastics industry.
Running alongside the Compounding World Expo and the Plastics Recycling World Expo, the Plastics Extrusion World Expo will build on their shows from the past to provide a bigger and better networking event for industry colleagues and enthusiasts.
The event is shaping up to be one of the biggest plastics industry gathering in the USA, building on from the success of AMI’s previous shows around Europe.

Tri-Mack Plastics Manufacturing Corporation unveiled the results of a recently completed test demonstrating the bond strength of over-moulded thermoplastic composite hybrid parts.
Validating the performance of hybrid composites, the bond between the unidirectional thermoplastic composite and the injection-moulded thermoplastic was shown to be twice as strong as industry standard adhesive and 85% the strength of the base laminate.
This multilayer material is structurally stronger and simpler to process whilst using less energy to do so.

Acrylonitrile Butadiene Styrene (ABS) is a thermoplastic. This means that this type of plastic will respond to heat, so it can be moulded or extruded when heat is applied.
When ABS and other thermoplastics are heated they melt, allowing them to be extruded. This means that they are reusable and can be recycled.
How is it made?
ABS is commonly created through the process of emulsion. This process entails mixing materials which don’t typically combine, forming one product.
As we mentioned before, ABS can be reused and recycled, so a lot of ABS products are made from recycled material, or have a percentage of recycled material in them.

As a whole, the UK consumes over 3.3 million tonnes of plastic products every year, and for many industries plastic is a necessity. So, the prospect of three-quarters of this being replaced with recycled plastics is an appealing thought for many of us.
Currently, the UK is only recycling 9% of the total amount of plastic we use; the rest is exported to be recycled abroad.
Recently a report from Green Alliance stated putting taxes onto products made from ‘virgin’ plastics could encourage an additional 2 million tonnes of plastics to be recycled in the UK, and used within our industries.

High Impact Polystyrene is one of the many materials we can use in the plastic extrusion process, but what actually is this material and why is it useful?
What is it?
HIPS (High Impact Polystyrene) is a type of thermoplastic; this means that is it mouldable when heated and solidifies when it cools.
Most people are familiar with general polystyrene, the difference between this and HIPS is that HIPS has been modified with rubber to make it more impact resistant.
The popularity of this material is down to its versatility, high impact strength and rigidity.

This blog is something a little different from our usual posts, but we thought it was time to let you in on our family-run firm so that you can learn a little bit more about Rayda Plastics.
Our Premises
Rayda Plastics was founded in 1976 by Ray Vincent and has been continually growing ever since. Our first home was a 2,500 sq ft unit, from which we supplied the local Devon area with our products, mainly used in the agriculture and fishing industry.
