Your Challenge... |
|
Finding a plasticizer for your PVC applications that mimics DEHP (DOP) in terms of its processing capability and yet at the same time fulfilling both technical and toxicological requirements is a challenge.
On top of that, for medical applications, specific regulations and safe product or chemistry need to be taken into consideration.
|
|
The Solution...
|
GRINDSTED® SOFT-N-SAFE, a bio-based plasticizer containing 0% of phthalates and offering:
- Equivalent processing capability to DEHP,
- No need for major adjustments to the standard formulation in terms of plasticizing efficiency or gel-fusion temperatures unlike many products on the market.
- Good Low Temperature properties
- Clarity and Colour Hold in clear formulations
- Good Elongation at Break after Accelerated Ageing at 135°C for 7 days

In addition, using GRINDSTED® SOFT-N-SAFE means that no compromise has to be made on performance as illustrated in the following table:

(Provided by Danisco's compounder partner in the US)
GRINDSTED® SOFT-N-SAFE is based on Danisco's Food Ingredient chemistry and demonstrates a safe toxicological profile aligned with the needs of the medical industry. GRINDSTED® SOFT-N-SAFE passes stringent tests such as the ISO 10993 and various OECD tests on developmental and reproductive toxicity to back the overall image of safe chemistry.

Why it is unique?
|
Testimony from the spokesperson of Danisco's partner in the US who implemented this solution:
"Finding a non-phthalate plasticizer that makes no compromises has been quite a task and whilst there are options on the market that purport to be 'drop-in' replacements we found only one to be almost identical to the DEHP in terms of its ease of use"
