RAYDA PLASTICS - MAKING HIGH QUALITY EXTRUSION PRODUCTS SINCE 1976.
There are plastic innovations left, right and centre, but this one has caught a lot of people’s eye. Maybe because Tesco is such a large, influential company and this step is the first of its kind for Supermarkets.
What Did Tesco Do?
A Tesco Extra store in Scotland has recently used a slightly different approach to resurfacing their car park: in the form of recycled plastics.

TPV is the new material which has bridged the gap between plastics and rubber. Increasingly designers are turning to TPV as their material of choice, but why is this hybrid becoming so popular?
What is TPV?
TPV, also known by its full name of Thermoplastic Vulcanisate, is a form of rubber which has been vulcanised during the compounding process. This means that the polymers are converted into more durable materials through the introduction of crosslinks.

A prime polymer is the natural source of the polymer; this means it will be the pure form of the polymer. Whereas when a prime polymer contains recycled content, it is using polymers that have been previously used.
Historically, recycled content meant the polymer would be traded at a lower value compared to the same prime pure polymers. This decrease in value is associated with a few key points:

PVC and PVCu are two common plastic polymers for use in everyday life, but some people are unaware they these polymers have many similarities but are also very different in the properties that they hold.
PVC
PVC is the most commonly used thermoplastic in everyday life; most people will have heard of this polymer. It is also known by its full name: Polyvinyl Chloride.

There are always plenty of innovations happening in the world of plastics, but one that recently caught our eye was this protective “goo”. It may seem a little odd, but the science behind this new product is incredibly clever.
What Is It?
This protective substance has been designed and manufactured by the company D30. They have called this substance the Impact Additive and it combines advanced polymer chemistry to achieve the protective features when mixed with TPR (Thermoplastics Rubber).
It allows traditional TRP products to have added impact protection without impacting the comfort or flexibility of the product. This plastic is even sustainable in extremely hot or cold conditions.

Plastics can take many different forms and have a variety of properties, but all end products start off as the raw material: resin. The process can be complicated and take many forms, but there are a few basic steps which all plastic extrusion processes follow.
Step One
The raw materials are fed into a hopper which goes to the extruder; this is located at the top of the machine. This means that gravity will feed the pellets into the barrel of the extruder. At this moment in the process, any additives or colourants are added into the mix when appropriate for the outcome.

In May 2018, the UK launched a plastic innovation hub along with other Commonwealth countries. The UK will play a leading role in the designing and the implication of the framework that this hub will use.
The Issue with Single-Use Plastics
You have probably seen the issue that the world is facing in the News or read about it in an article because the story is everywhere at the moment and for a good reason. The issue is the plastic waste that is polluting the world’s oceans and the marine life within these waters.

Plastics have been used in the automotive industry for many years, affording many benefits and in fact the frequent innovations in plastics have been a large factor for the advances in the automotive industry.
Plastics have so many useful properties that can be modified and altered to become the perfect material for vehicles and the different requirements that each area needs. This is why plastics have always been a popular choice for the automotive industry.

There are innovations in the plastics industry all the time, this allows the material to be constantly improving and become more and more useful for industries. One of the largest impacts plastic has made is actually in safety and the safety of workers in a lot of industries.
The properties that plastics have are extremely useful for a lot of sectors. Plastics are durable, sustainable, long lasting and even flexible. This allows them to change and shift depending on their intended use. Safety has improved a lot over the years and a majority of this development is down to the innovations of plastics for safety purposes.

Plastics have had a revolutionary impact on the medical industry, making procedures simpler and safer. They have been a contributing factor in reduced medical costs, a reduction in infectious diseases and have improved forms of pain management.
Sterility
Plastics completely revolutionised this aspect of medicine allowing practitioners to have sterilised equipment quickly and easily. Plastics allow for “one-time use” products, they are completely sterile and can be thrown away once used. These include: surgical gloves, syringes, insulin pens and IV tubes.
