Hexamoll Dinch - A Non Phthalate Plasticizer: For
Medical Devices And Food Contact Application
Hexamoll® DINCH® - a Non Phthalate Plasticizer is an
alternate to Phthalate Plasticizers specially
developed for use in sensitive applications like
Medical Devices & Food Contact Application items.
The
safe Plasticizer is the most sustainable non-phthalate
plasticizer. As a matter of fact, DINCH was ranked
first in the recently updated eco-efficiency analysis
comparing different plasticizers. Since 2002 Hexamoll®
DINCH® is an established plasticizer in the market and
offers maximum safety. Several leading brands in toy
and medical industry now put their trust in this
alternative plasticizer.
Chemically, it belongs to the family of aliphatic
esters:
It
offers excellent formulation performance when compared
with common ortho & non ortho phthalates. It has
processing characteristics similar to DEHP, however,
because of its higher molecular weight, it needs
slightly higher processing temperature on
Mixer/extruder.
Various
studies on DINCH have shown that it is not a
carcinogen or a mutagen, it shows no reproductive
toxicity. With DINCH based compounds, it is possible
to produce medical devices that comply with:
EU
Council Directive 93/42/EEC (as amended by Directive
2007/47)
DIN EN
ISO 10993 for cyco-toxicity, haemolysis, absence of
pyrogens, irritation & sensitization, systemic
injection, intracutaneous and implant tests to fulfill
the requirements of United States Pharmacopeia (USP),
monograph 88, Class VI
Main
applications for DINCH based compounds are:
-
Dialysis Tubing
-
Intravenous therapy
-
Blood Bags
-
Masks
-
Enteral Feeding
-
Catheters
-
Gloves

Comparing Polycarbonate and Copolyester Resins For
Injection Moulded Medical Components
Both
physical properties and processability play key roles
when injection-molded parts are mass-produced. When
producing medical parts, a consistent, high degree of
accuracy is also vital. It is relatively simple to
adjust a process to account for differences in
molecular weight once that process is optimized for a
specific polymer. It is much more complex to adjust
the process for changes in polymers.
The
three transparent resins - a standard medical grade
polycarbonate, a high heat polycarbonate, and a
medical copolyester resin are compared here.
The
medical copolyester stands for the greater weight
variability. It is at least partially due to the
greater viscosity fluctuations that copolymers undergo
as well as the greater viscosity fluctuations with
temperature change.
While
using for a medical device, the energy consumption of
each of the three resins can be found out. Energy
consumption for the copolyester resin is greater than
the two polycarbonate resins. Going against
conventional wisdom, increasing the polycarbonate
resins’ melt temperatures actually reduces the energy
consumed per part.

PET Has
Advantages For Medical Packaging
PET
might not be ideal for many medical applications,
including devices, but it can serve as the perfect
plastic for packaging for devices.
Because
of the routine nature of hospitals and the health care
industry, it is set up nicely for a recycling system
where device packaging made out of PET can be easily
recycled and returned to the market at a very clean
and high grade. Because of the wealth of products PET
can be made into, the market for PET is so much better
compared to polystyrene and PVC.
PET has
great attributes like clarity and toughness. And it’s
easy to process. PET has a long history without any
regulatory issues. And while it is widely available
and easily recycled, the recycling rate for the
material is only at approximately 30%. That contrasts
with more than a 60% recycling rate for aluminum.
While
using PET for packaging for medical devices, purity is
very essential as that will make it as recyclable as
possible. PET and PVC together should not be used as
PET degrades the PVC.
In
addition to traditional PET, there’s the emerging
bio-derived PET market too which also can be used for
packaging as well.
