Laboratory Tubing

Laboratory Grade Rubber Tubing

Laboratory tubing can be manufactured in many different materials, Silicone Rubber being one of the most popular. The specific grade and hardness selected will be driven by what the tube is doing, and what it is transporting.

Common applications are waste disposal of product, in which case a general purpose silicone with Medical/food and drink certification would do. Anything else largely depends on what the tube needs to transport, and advice from compatibility tables should be sought to ensure the most suitable material is selected.

Viton or Fluorosilicone would be required where chemical resistance is needed, where steam is present a steam resistant grade of silicone should be sought, and if temperatures fall outside of -40 to + 160 degrees C specialist grades should be used.

Tubing can be used in fluid transfer or Peristaltic Pump activity. Whatever the need Adpol has the capability and expertise to help you find a solution, often manufactured in house.

Anti Viral Rubber?

Given the current virus pandemic and need to try and carry on as safely as possible in a multitude of different circumstances the need for Virus inhibiting or destroying surfaces or coatings is probably higher than ever. But does such a product exist?

Good quality Silicone Rubber has natural resistance to microbiological growth such as mold, mildew and fungi. With specialist additives this can be enhanced to offer proven resistance to EColi and MRSA.

In terms of Virus resistance for rubbers a promising area of development has been with the addition of Silver particles into rubber, but as you can imagine this is very expensive, and results not that dynamic yet.

Probably the best protection you can offer through any Virus resistance of rubber products is regular clean downs with alcohol based products, or high temperature deep cleans. We know Silicone Rubber copes well with alcohol based cleaners and high temperature washes, so will be one of the obvious choices for rubber products with this in mind.

So for maximum anti viral protection from rubber products our advice is regular and thorough wash downs.

Platinum Vs Peroxide Cured Silicone

Silicone Rubber, regardless of colour, hardness or type can be cured in one of two ways. Platinum (addition) Cure system or the more traditional Peroxide Cure system, both have pros and cons and both suit certain applications.

Both our Peroxide and Platinum cured silicone compounds meet food, drink, medical and flammability standards.

The curing process is basically the cross linking of the molecular “mesh” structure of the Silicone as heat activates the catalyst and the gum turns into rubber as we know it. The better and tighter the cross linking of the “mesh” the better the technical performance of the Silicone.

Peroxide catalysts are the mainstream in our industry, they offer the overall best value and good performance, but residue from the cross linking can remain in the Silicone and relies on a good post cure process to drive this off. Translucent rubber will not be quite as clear and can yellow over time.

Platinum Curing systems tend to be more expensive, and the processing more involved. But it is effectively a cleaner cure system leaving little or no residue. This means that you have far less risk of any trace residue getting into product coming into contact with the rubber, and the clarity/surface finish will also be better.

Platinum Cured Silicones are more suited to critical food/drink and medical applications, or where the highest cosmetic appearance is required. Peroxide Cured Silicones are absolutely fine for the majority of applications.

We are very happy to discuss your individual needs, advise on what we think is the most suitable material and extrusion and send samples if required. Always happy to help, please just get in touch

Product and Supply Update Regarding COVID-19

With more companies suspending operations due to the ongoing Covid 19 situation we just wanted to reassure our customers that Adpol remains open for business and here to assist.

Extrusion, moulding and gasket fabrication continues, at a slightly reduced capacity rate which means that we are closing at 4pm Monday – Thursday and 1pm Friday, but please email if you need to contact us outside these hours.

Adpol manufactures for many sectors, including medical, pharma research, food, drink and dairy with compounds fully certified in medical, food and drink sectors. This means we are required to remain open by many key UK manufacturers in these sectors. We are already involved in a number of new medical projects directly linked to the Covid 19 situation, and are still able to prioritise these into days lead time (product allowing) where needed.

So if you are asked to get involved in a medical project we are able and have the materials and expertise to help you, please give us a call or send us details and we will get back to you ASAP.

It is great to hear so many positive stories around UK manufacturers working together to combat this virus, and all of us at Adpol are keen to play our part and help you do likewise in any way we can.

Brexit Preparations- Lead Times and New Products

Brexit Preparations… How we can help you prepare

You are probably getting regular questionnaires from your customers

about your preparations and risk analysis for Brexit. An area to consider

and reduce risk for those based in the UK is sourcing within the UK to

avoid any border issues. We can reverse engineer most silicone rubber

extrusions within 3 weeks and remove the risk, or at least give you a back

up option for your plan. So if you have any overseas suppliers for sponge

or rubber parts it might be worth talking to us, sooner rather than later.

2019 Pricing Notifications

Thank you for your support in 2018, and patience with the price rises that

you have seen. Regrettably the large price rises on raw material trends are

continuing into 2019 as the chemical shortages and growing global

demand for Silicone continue.

This is affecting all Silicone compounders, and manufacturers like us, we

are all faced with price rises on raw material of up to 40% in 2019 so far. We

use the best value quality European compounded Silicone available which

is purchased in high volumes for the best rates. Like for like comparisons

are more expensive.
