Why Silicone Rubber Is the Perfect Material for Medical Applications

The disadvantages of utilizing latex rubber to be used with people is effectively documented. Certainly, we have now seen quite a few materials substitutions from latex to silicone throughout many industries. This text will give attention to the growing use of silicone rubber within the medical business.

Silicone rubber is inherently a non poisonous, bio-compatible materials. Opposite to the lawsuits relating to silicone implants within the 1990s (and the destructive publicity which adopted), silicone rubber is a secure materials. I am not going to say you may feed it to your canine because the animal may choke on it, however it would not poison it!

So, silicone rubber has the next benefits over different supplies relating to medical functions:

* It’s biocompatible and non poisonous

* It withstands frequent sterilization strategies e.g. autoclave

* It has an working temperature vary of -50Âșc to +250

* It may be provided in a hardness starting from 10 to 90 Shore A

* It may be pigmented to nearly any color

* It’s inherently flame retardant

* It’s climate and ozone resistant

* It’s electrically conductive or insulating

The next varieties of silicone rubber are sometimes used for his or her medical functions:

* Excessive Consistency Silicone Rubber (HCR) – both platinum or peroxide cured;

* Liquid Silicone Rubber (LSR) which is platinum cured.

The present development is for merchandise to be manufactured in liquid silicone rubber, however there may be nonetheless a major place for the extra conventional HCR.

The recognition of liquid silicone rubber has elevated as it’s a excessive purity platinum-cure silicone, and medical machine producers are eager on its wonderful half high quality. Furthermore, the decreased human contact throughout processing reduces the chance of contamination, particularly when manufactured in a clear room atmosphere. LSR is often provided in two components with one of many components containing the platinum catalyst. These are then robotically blended with any colors and components which can be required. The blending produces a really homogeneous materials that results in merchandise that aren’t solely very constant all through the half, but in addition from half to half.

Okay, so the platinum cured liquid silicone is clearly an important materials. Nonetheless, there are drawbacks relating to liquid silicone. Initially is the price of the tooling. The clue is within the identify – ‘liquid’. The tooling requires excessive precision and workmanship to forestall the fabric going the place is should not! Additionally, as this materials lends itself to producing small elements the tooling is usually automated. This ends in a really costly instrument. In fact, with very excessive quantity components the payback time will not be too lengthy even with very costly instruments, however what if you do not have a excessive quantity requirement? The second downside is that there’s much less scope to change the fabric. It is because it it provided in sealed drums from a suppliers mixing giant portions of a restricted variety of normal grades. That is nice if that grade of LSR meets your wants, however not so nice for those who want a customized Custom Silicone Craft Mat silicone rubber.

Each the excessive consistency and liquid silicone supplies meets or exceed the next globally recognised high quality requirements:

* ISO 10993

* US Pharmacopoeia Class VI

* European Pharmacopoeia three.1.9

* FDA CFR177.2600

* BfR and FDA Meals Contact Rules

So, silicone rubber is the right materials for medical functions. We already knew this. The pondering is required as as to if you utilize an LSR or extra taditional HCR materials.
